Lab tested and verified
Every batch is independently tested by accredited U.S. laboratories. We don't ask you to take our word for it - we hand you the proof, on the record, with every lot.
Verified potency
Every vial is assayed by HPLC to confirm it contains exactly what the label states, quantified against a reference standard - no approximations.
Why it matters: peptide content directly determines research outcomes. Underdosed vials waste time and confound the data.

We run six assays on every batch, and nothing is released until all six results are on file.
Sterility, USP <71>
We culture every batch for fourteen days before inspection, because slow-growing organisms won't appear in a two-day check.
Endotoxin, USP <85>
Endotoxins survive sterilization and stay biologically active, so we screen every batch by LAL against pyrogen limits.
Purity, HPLC-UV
We measure against a ≥99% target and publish your lot's actual number without rounding it up.
Identity, LC-MS
Mass spec weighs the molecule against the sequence on the label, so a near-miss compound reads as the wrong mass.
Heavy Metals, ICP-MS
Lead, arsenic, cadmium and mercury arrive with the raw materials and are invisible to HPLC, so we run a separate instrument.
Net Content
We weigh what's in the vial, so a 10 mg vial is confirmed to hold 10 mg.
