hGH Fragment 176-191
Numerous studies have shown that this peptide may represent numerous opportunities for competent scientists to investigate, especially cartilage regeneration and fatty tissue mitigation.
What is Fragment 176-191 peptide?
This synthetic amino acid sequence mimics the hGH sequence, starting from position 177 to position 191.
AOD 9604, or “lipolytic extract,” is another name for Fragment 176-191. Many researchers argue that Fragment 177-191 may be an important research compound in the context of obesity. They believe it can potentially burn fat in animal models in laboratory settings.
Despite positive results, Fragment 176-191 hasn’t been used for human research purposes and doesn’t have official medical approvals.
Growth hormone
According to research, it appears that hGH Fragment 176-191 may not produce any side effects often related to hGH supplementation. Several adverse effects, such as, impaired glucose tolerance, insulin resistance, and increases in IGF-a levels, have cast doubt on hGH’s use as an obesity treatment. However, when it comes to hGH Fragment 176-191, it doesn’t seem to be impacting blood IGF-1 levels or negatively affecting carbohydrate metabolism.
A trial conducted on Zucker rats in 2000 showed no detrimental effects on insulin sensitivity. Also, an investigation on obese mice done in 2001 did not seem to affect insulin secretion.
Properties
Studies conducted on animals suggest that this peptide can exhibit significant theoretical properties, which will be outlined below:
- The main potential of this Fragment is its lipolytic properties or, in other words, fat-reducing potential. While growth hormones promote development in infancy, they have also been speculated to have an important purpose in maturity.
- Lipoprotein lipase inhibitors may be activated in fat cells,
- By stimulating lipolysis in adipocytes may lead to a decrease in fat cell bulk,
- It might lead to loss of fat from the host body,
Weight
A 14-day trial researching overweight mice came to a conclusion that Fragment 176-191 may have increased skeletal muscle thermogenesis and boosted fat burning.
The study results indicated that this peptide may have enhanced beta (3)-AR RNA (ADRB3) levels, which caused rapid weight reduction in overweight animals but didn’t have much effect on lean mice.
Cartilage
Based on other animal research, it appears that hGH Fragment 176-191 may boost the effects of hyaluronic acid (HA). When Fragment 176-191 was combined with hyaluronic acid, it might boost cartilage formation in white rabbits which have issues with osteoporosis.

Ipamorelin is a pentapeptide that showed a significant growth hormone secretion potential both in vitro and in vivo studies. In vivo studies, it showed a similar potency and effectiveness as GHRP-6 (a synthetic growth hormone-releasing hexapeptide) as it stimulates GH release via the GHRP receptors.
What’s interesting about ipamorelin is that it did not raise ACTH (Adrenocorticotropic hormone) nor cortisol level significantly; something we’ve seen happening with GHRP-6 and GHRP-2. So, we can conclude that ipamorelin is the first GHRP-receptor agonist with GH release selectivity similar to GHRH. This is why ipamorelin is an interesting candidate for further testing.
In addition to stimulating GH secretion, this peptide has seen some interesting use in the treatment of postoperative ileus (POI), a condition characterized by transient loss of gastrointestinal motility following abdominal surgery.
The exact mechanism behind POI is a complex one, involving many different bodily structures; in addition, condition is often worsen due to the opioid drugs used for patient pain management.
In rodent studies, ipamorelin was found to selectively stimulate ghrelin (hormone produced by our stomach, affecting food intake, deposition and growth hormone release) without raising cortisol or adrenocorticotropic hormone levels. These effects were shown in both lower GI tract as well as the upper, making this peptide a viable candidate for potential POI treatment.

CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH) and growth hormone secretagogue (GHS) developed by ConjuChem Biotechnologies.
GHRH is a 44-amino acid long peptide which our hypothalamus synthesizes and in the pituitary gland, it binds to the growth hormone (GH) receptors, resulting in the release, regulation and pulsatile secretion of GH.
We already talked about GH therapy as being FDA approved in conditions such as GH deficiency, Turner syndrome, Prader-Willi syndrome, idiopathic short stature etc. Recombinant human GH treatment is generally performed as one daily, subcutaneous injection which elevates the levels of GH serum in the blood.
One of the major problems with this approach to treatment is that the efficacy of GH therapy is hard to determine due to the lack of biological serum biomarkers. Currently, most facilities are using levels of IGF-1 and IGFBP-3 to monitor the efficacy of this therapy but these levels may vary wildly (due to growth velocity, glucose tolerance, insulin levels etc.).
Furthermore, GH abuse extended across multiple sports disciplines, making it even harder to suppress and put this problem under control.
Researchers hope to solve this problem by employing new biomarkers of GH action and secretion. One such way is to employ newly developed molecules, such as CJC-1295, shown to increase both GH and IGF-1 levels in the blood, without affecting the pulsatility of GH secretion. CJC-1295 also has a prolonged half-life of 8 to 10 days, due to its ability to bind to the endogenous serum albumin.
So, what scientists are hoping to achieve with CJC-1295 is both a safe way of promoting GH secretion as well as making it measurable in a laboratory setting. There were numerous studies tackling this issue, but we still need further testing to confirm these preliminary findings.

Growth hormone replacement therapy has long been accepted as one of the most effective ways of treating GH deficiency and related conditions. This therapy uses recombinant human growth hormone (rhGH) and, despite its longstanding usage record, it has been surrounded by controversy. Even though, in the short term, this therapy is very effective, when it comes to long term effects, issues start to arise:
- Long term improper dosage can lead to some severe side effects
- This therapy may affect normal physiology after prolonged application
- Some federal regulations might interfere with the therapy
- There’s even some concerns that this therapy may awaken latent cancers and cause metabolic disorders
There is one more major problem with dosage because the body can’t properly modulate tissue exposure to rhGH. Meaning, the practitioner uses their “best guess” to access the appropriate dosage.
This is why researchers are looking for alternative ways to stimulate GH production by targeting GH secretagogues and promoting pituitary gland health. One such molecule is sermorelin, a GHRH analog that impacts the hypothalamic-pituitary-pituitary-somatotropic axis.
It’s used for both treatment and diagnosis of GH deficiency as research studies showed sermorelin promoted change in GH levels similar to those observed with endogenous GHRH. It also stimulates FSH (follicle-stimulating hormone) and LH (luteinizing hormone), which implies a potential role in the treatment of hypogonadism.
Though we need larger, longitudinal studies, sermorelin proved as a promising GH and IGF-1 stimulator and diagnostic agent.

Obesity’s become a global pandemic, currently affecting one third of the entire population, and this is why we can look at it as a chronic disease that requires appropriate treatment.
When talking about obesity, amylin hormone is of great importance as it gets secreted along with insulin and acts as food intake inhibitor, delaying gastric emptying and suppresses post-prandial glucagon responses to meals.
For this reason, there is a tendency to include amylin management in newly developed medication.
And one such compound is cagrilintide – lipidated long-acting amylin analogue.
Though it still hadn’t been thoroughly tested on humans, numerous rat studies showed incredible potential. One such in vitro study involving rats set out to compare cagrilintide’s effectiveness against pramlintide (an FDA-approved diabetes 1/2 medication).
The study showed that pramlintide reduced food intake by 25% in the period of 0-24 hours (it did not cause reduced food intake after 24 hours). But the dosage was substantial – 1000 nmol/kg.
On the other hand, cagrilintide was able to reduce food intake by approximately 50% with a minimal dosage of only 3 nmol/kg. More importantly, this food intake reduction spanned across 60 hours from the moment it was injected.
These results clearly show the potency of cagrilintide in weight loss and diabetes management medication, especially because it acts over such a long time period (allowing subcutaneous injections to be applied once a week).

Also called Bremelanotide, PT-141 is a synthetic melanocortin receptor agonist that promotes dopamine release. Since it has such a high affinity for MC4R (Melanocortin 4 Receptor), in the presynaptic neurons of the hypothalamus, it has been approved as a treatment for HSDD (hypoactive sexual desire disorder) in premenopausal women. Under the brand name Vyleesi, Bremelanotide is the first and only FDA-approved way of HSDD treatment.
Sexual Dysfunctions
As we already said, PT-141 is an effective treatment for HSDD in premenopausal women but it’s important to note it should not be used as a treatment in women who already went through menopause or as a way of boosting sexual performance in men. These have not yet been fully tested.
We’ve seen the effectiveness of PT-141 (Bremelanotide) demonstrated in numerous studies. One such study followed female test subjects over the course of 52 weeks where the treated group received a 1.75mg dose right before anticipated sexual intercourse. All participants showed higher scores on general arousal, desire and orgasm, as compared to the placebo group. Also, no major side effects were linked to PT-141 application – the “most severe” ones were nausea, flushing and headache, which only occurred in around 10% of the participants.
Interestingly enough, scientists are still unsure about the Bremelanotide’s exact mechanism of action and how it leads to increased sexual desire in female patients. All we know is that it’s a potent alpha melanocyte-stimulating hormone, binding predominantly to the receptors MC4R and MC1R, and, to a certain extent, to MC1R-MC5R.
PT-141 And Erectile Dysfunction
At the beginning of the article we said that PT-141 (bremelanotide) should not be used to increase sexual desire in men… but this is not entirely true as there is some emerging evidence that this peptide does affect male sexual performance.
Currently, there are a number of effective ED treatment options available. One of the most fail-proof and common ones, incidentally the most invasive one, is an intracavernosal injection – where an injection is applied directly to corpus cavernosum (spongy tissue that runs through the shaft of the penis).
Naturally, researchers are on the lookout for a new, less invasive treatment option and are testing PT-141 as such. Though research is still in its early stages, results showed significant increases in both duration and the erection quality in both “regular” men, as well as those known to be taking viagra.
We still need more research to confirm all these findings and determine the safety and efficacy of using PT-14 as a reliable ED treatment option, but clinical studies suggest we are heading in this direction.

Tesamorelin is a 44 amino acid long, synthetic growth hormone releasing hormone (GHRH) analogue. It was primarily developed and used to treat visceral fat buildup in HIV positive patients suffering from lipodystrophy (a condition characterized by abnormal fat distribution).
Tesamorelin peptide activates GHRH receptors in the pituitary gland, resulting in growth hormone synthesis and release. This GH release further stimulates the production of Ilike growth factor-1 (IGF-1), which is naturally low in obese and diabetic patients.
The good thing about tesamorelin is that it was approved in the US back in 2010 for the treatment of abdominal fat in HIV positive patients as a part of the antiviral therapy-related lipodystrophy. It has also been evaluated as a potential therapy of insulin resistance, nonalcoholic fatty liver and, of course, obesity. These clinical studies are still ongoing and we’ll need more information to confirm its effectiveness.
The usual tesamorelin dosage for patients is 2mg given in the form of a subcutaneous injection, once a week. As for the side effects, patients did not report that many, but from the ones we have documented, most common are:
- Application site irritation
- Itching
- Peripheral edema
- Mild nausea
- Redness
More importantly, tirzepatide therapy was not associated with hepatotoxicity and is very unlikely to cause any clinically apparent liver injuries.

If you’re a peptide researcher (or plan on becoming one), you should know the difference between CJC-1295 and CJC-1295 DAC. CJC-1295 DAC features an additional component at the end of the peptide chain, also known as a drug affinity complex or DAC.
This small fragment changes the peptide’s functionality and extends its half-life to six to eight days. It might have a prolonged effect of up to two weeks.
Below, we will showcase the main similarities and differences between these two peptides, including their properties, characteristics, and mechanism of action.
What is CJC-1295 DAC peptide?
This peptide resembles the regular CJC-1925 since it is a modified form of natural GHGR (1-29). However, this one differs from CJC-1925. It has an additional molecule known as a “drug affinity complex.”
DAC features a couple of oxygen and nitrogen atoms connected by chemical bonds. According to some findings, this small number of atoms could significantly impact peptide breakdown rate and its use in the body.
What is CJC-1295 Peptide?
This peptide is also known as “modified growth hormone releasing factor (1-29)”, “ModGRF 1-29”, or “Modified GRF (1-29).” You may also encounter the name “CJC-1295, without DAC.”
All these names imply a specific peptide molecule containing a short amino acid chain. As many studies have indicated, this peptide may boost growth hormones in the bloodstream.
Growth hormone may have a significant role in several vital internal activities. It could facilitate cellular reproduction, repair, and growth, help with tissue repair, improve muscle cell development, support skin cells, and other functions.
While the body naturally produces growth hormone, this production tends to naturally decrease. According to some research done in laboratory settings, CJC-1295 may encourage the natural production of growth hormone, increasing its levels, which could lead to quicker repair, fat cell burn, and muscle cell growth.
Differences between CJC-1295 DAC and CJC-1295
As research studies have outlined, here are some fundamental differences between these two peptides.
Half-life
The main distinction lies in their half-lives. CJC-1295 is thought to mimic the body’s natural peptide. The endogenous GHRH has a short half-life of just a couple of minutes. Similarly, CJC-1295 has a brief half-life of around half an hour.
Regarding the second peptide, the additional DAC could significantly alter the organism’s peptide use. Researchers believe that DAC offers a peptide, a lysine linker, which could protect and prevent it from degrading.
Moreover, the DAC component could extend the half-life of this peptide to about six to eight days.
Properties of CJC-1295 DAC peptide
It is believed that CJC-1295 DAC boosts growth hormone levels in the bloodstream. Additionally, several studies suggest the following:
- Scientists and researchers need to focus their attention to studying the potential of growth hormones on growth and muscle recovery.
- Growth hormone may help convert fatty tissue into energy.
- Growth hormones are linked with collagen production in the skin, which means this peptide may also help with skin regeneration and skin cell development.
- CJC-1295 DAC may positively impact sleep patterns.
- Growth hormone is essential for tissue regeneration and helps the organism recover from damage.

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist.It is one of the two primary hormones that may enhance incretin activity in rodent models, along with GIP.
GLP-1 is one of the major incretin (gut peptide secreted after nutrient intake) hormones in humans. It plays a pivotal role in many different mechanisms within the body:
- Insulin secretion
- Inhibits glucagon release (glucagon is secreted as a response in blood sugar drop)
- Suppresses hepatic gluconeogenesis (glycogen is the primary carbohydrate stored in the liver)
- Delays gastric emptying
- Reduces appetite and energy intake
When talking about obese diabetic 2 type patients, GLP-1 assumes a special status in their treatment as it lowers HbA1c levels along with body weight, but without the risk of hypoglycemia.
However, the biggest problem with GLP-1 is its short half-live (of only 1 to 2 minutes) and this is why researchers turner to various other GLP-1 receptor agonists, such as liraglutide, dulaglutide and, of course, semaglutide. Another thing researchers hope to achieve by turning to GLP-1 agonists, such as semaglutide, is to develop an effective diabetes management drug which needs less frequent dosing.
Murine models suggested that semaglutide’s GLP-1 receptor activation affects insulin secretion, blood sugar homeostasis and beta cell protection. Further, in vitro studies showed its potential to also affect glucagon secretion. This insulin glucagon mechanics is what’s used to balance our pancreatic function and regulate metabolism.

Epitalon is a synthetic peptide, made up of 4 amino acids – alanine, glycine, glutamic and aspartic acid. It’s based on a natural peptide epithalamion, commonly extracted from the pineal gland. Some earlier studies showed epitalon’s antioxidant potential, so more recent ones started focusing on its anti-aging potential.
Recent studies also showed its potential in regulating DNA changes, treating infectious diseases… even addressing some types of cancer.
Anti Aging Properties
The fact that epitalon is epithalamin’s extract, means it has the ability to eliminate free radicals that cause tissue damage. A particular research study on flies and mice showed that, after epitalon’s administration, fruit flies mortality rate dropped by a whopping 52%, while the mortality rate in rats dropped by 27%, as compared to the control studies. What researchers learned from this study was that regular epitalon administration stimulated the synthesis and secretion of melatonin, which inhibits free radical production and its subsequent damage.
There was another in vitro study on human somatic non-reproductive cells suggesting that epitalon peptide affects telomerase activity. Telomerase is an enzyme present in cells, allowing them to live longer. So, essentially, this study showed the researchers that this therapy leads to the prolonged cell lifespan. Of course, we still need full scale human studies to see the full extent of prolonged cell lifespan.
DNA Effects
Epitalon also interacts with DNA gene expression, allowing it to have an indirect effect on a whole host of potential bodily functions – from immune system, to skin, tendon and connective tissue repair.
This essentially allows epitalon peptide therapy to have a dual potential effect – on the one hand, it strengthens the immune system and protects the body from outside factors, and on the other, it allows the body to repair and regenerate its structures on its own.
Skin Cell Regeneration
We already talked about epitalon’s effect on DNA and genes. This effect extends to the fibroblast producing and maintaining MMP2. Interestingly, this peptide also affects other skin components, such as collagen and elastin.
Of course, we still have yet to see definitive human studies, but animal ones showed promising results. Young and old rats exposed to epitalon showed skin fibroblast proliferation of 29 and up to 45%. Not only that, epitalon also activates enzymes that slow down programmed cell death.

Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme that’s present in every living cell and, as such, is involved in a number of metabolic and cellular processes. This is why NAD+ is so interesting for many different areas of research such as:
- Anti aging
- Metabolic disorders
- Neurodegenerative disorders
- And even cancer research
PeptideShop.com sells NAD+ peptide in vials of 100mg and is meant for laboratory use only. Researchers commonly use it to test its effectiveness on:
- DNA damage repair and gene expression
- Stress response regulation
- Slowing down the progression of degenerative disorders
- Metabolism pathway testing
But, as previously mentioned, we are still waiting on large scale human tests.
NAD+ Role In Cellular Maintenance
Cellular NAD exists in two forms:
- NAD+
- NADH
When there’s a shift in NAD+ and its level drops in favor of NADH, this is a hallmark of aging; though the exact mechanisms that lead to this drop still remain unknown.
Naturally, numerous clinical studies showed that increasing NAD+ levels leads to the reduction of age-related immune and metabolic changes. Meaning there is potential of using NAD+ in treating age related disorders.
NAD+ And Neurodegenerative Disorders
When speaking about aging, one of the most contributing factors is mitochondrial dysfunction in neurons. Aging also speeds up the progression of neurodegenerative disorders, triggering DNA damage and mitochondrial impairment.
Luckily, studies have shown that NAD+ treatment (and even supplementation) helped restore mitochondrial function, enhance neural function and even improve cognitive abilities.
NAD+ And Metabolic Disorders
We’ve seen a dramatic increase in metabolic disorders lately, making it one of the major global health problems. Of course, we use the term metabolic disorders to cluster a whole host of problems such as obesity, diabetes, hypertension, as well as some cardiovascular pathologies.
NAD+ levels directly influence nutrient status in cells, so regulating them stands as a clear guideline to future research in hope of making NAD+ an FDA-approved way of treating metabolic and age related disorders.

TB-500 is a 43 amino acid long synthetic peptide, analogue of thymosin beta-4. Thymosin beta-4 is a widely distributed peptide, and present in virtually all mammalian cells, which plays a pivotal role in many different processes in the body – it increases angiogenesis (formation of new blood vessels), proliferation, inhibits apoptosis (cell death) and inflammation.
Numerous animal clinical trials also showed that thymosin beta-4 can be used to indicate myocardial, liver and renal problems.
Angiogenesis:
Thymosin beta-4 promotes angiogenesis, triggers cell proliferation and migration, as well as the formation of capillary-like structures in cells. It also triggers blood perfusion (local fluid flow) by increasing capillary density.
Apoptosis:
Thymosin beta-4 inhibits apoptosis by inhibiting the transforming growth factor pathway. It also prevents nucleus pulposus (spinal disk providing shock absorption during movement) cell apoptosis and slows down cellular aging.
Inflammation:
In mouse models Tβ4 significantly dropped the number of inflammatory cells in the brains of the treated animals. It also prevented the production of proinflammatory cytokines and effectively blocked the increase of ethanol-induced inflammatory factors.
Heart Health:
Clinical data showed that thymosin beta-4 has a positive effect on both acute phase (immediately following the injury) where it preserves the ischemic myocardium, as well as in the chronic phase, in which it activates the growth of vascular cells.
After observing Tβ4’s benefits in animal models, it’s not surprising TB-500 gained so much popularity recently, since it acts as Tβ4’s synthetic analogue. Numerous clinical studies (in animal models) showed TB-500 as a potent way to improve blood vessel growth and fluid flow, accelerate wound healing, reduce oxidative stress and bind protein.
Of course, more research is needed to determine the full effects of this peptide, its safety and effectiveness in human test subjects.

BPC-157 is a native gastric pentadecapeptide (composed of 15 amino acids), derivative of body protection compound (BPC). Being a gastric peptide allows for good oral availability and remaining stable for more than 24 hours in human gastric juice. Furthermore, there is no need for a carrier which makes this peptide unique, as compared to others that depend on it.
Clinical studies showed that BPC-157 is highly effective in both treatment and prophylaxis of various gastrointestinal lesions. This effectiveness spans to cover both acute and chronic gastric conditions, intravenous, ingastric, and even as a topical agent for deep skin burns and lesions.
Surprisingly, BPC-157 has also shown a beneficial effect on:
- Brain lesions – in one of the most recent studies researchers concluded that BPC-157 expressed a direct therapeutic effect in rat test subjects following a stroke. This peptide not only delayed neural damage, but also promoted full functional recovery.
- Behavioral disorders – medical research showed that BPC-157 counteracted catalepsy (a state of a trance or a seizure) in rat models. This research indicated a connection between BPC-157 and dopamine as well as glutamate and nitric oxide system (vital in schizophrenia therapy).
- Spinal cord injuries – A particularly interesting study showed that BPC-157 administration to rats with spinal cord injuries resulted in improvements mere 10 minutes after the initial dosage. On the contrary, untreated rats did not fully recover days, weeks, months and, in some rare cases, years following the injury.
