PT-141

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.

FAQs

1. Peptide Usage:
Products you see on the website are strictly for scientific research purposes, designed for in vitro testing and lab experimentation. These products are not intended/cannot be used as foods, drugs or cosmetics, any sort of bodily introduction of the products into humans or animals is strictly prohibited. We also do not condone misbranding, misuse, or mislabeling of our products in order to use them in any way other than in-vitro research studies.
2. Peptide Transport:
As previously mentioned, our products are in lyophilized form, stored in a glass container, to ensure maximum stability and safety during transport. As such, they do not require refrigeration in transport and can withstand short-term temperature fluctuation - even in extreme temperatures on the both spectrums (hot or cold).
3. Peptide Storage:
Since our products come in a lyophilized state, they are extremely stable and allow both short-term and long-term storage. For short-term storage, the most optimal temperature recommended is 39.2 degrees Fahrenheit (4 degrees Celsius). If you are opting for long-term storage, you need to use a freezer and a minimum temperature of -4 Fahrenheit (-20 Celsius), but preferably even lower. This will ensure peptide stability over the upcoming months, and even up to 1, 2 years. If you reconstitute the peptide, however, its longevity gets drastically reduced. Though it’s not recommended, you can also safely store reconstituted peptides at 39.2 degrees Fahrenheit, but not for more than 3 weeks. And if you drop the temperature to -4 Fahrenheit, you can store reconstituted peptides for up to 3, 4 months. Additional note: avoid repeated freeze thaw cycles as they degrade the peptide, reducing its stability and effectiveness.
