What the research says

Semaglutide is an analogue of human glucagon-like peptide-1 (GLP-1) with two amino-acid changes and a fatty-acid side chain. The changes protect it from the enzyme that breaks GLP-1 down within minutes, and the side chain binds it to albumin, giving it a half-life of about a week. The STEP 1 trial followed adults with overweight or obesity for 68 weeks (Wilding et al., N Engl J Med 2021). Semaglutide is the active ingredient of Ozempic and Wegovy, which received FDA approval. PeptoClinic's vial is not either of those products and is not approved by the FDA. Supplied as lyophilized powder in a sealed vial.

Each report covers the batch submitted for it and no other. It is evidence about that material rather than a guarantee about every vial ever shipped, which is why these are dated, numbered and published one at a time instead of summarised into a badge.

Frequently asked questions

How do I know a lot is what it claims to be?

From that lot's certificate of analysis, not from what the supplier asserts. The certificate names the laboratory that took the measurement, the date, the task number, the method and the purity found. PeptoClinic publishes the full reports uncropped, exactly as the laboratory printed them.

What is a certificate of analysis and how do you read one?

It is the report an analytical laboratory issues on a specific sample. Four things are worth checking: which compound it claims to have measured, by what method (HPLC for purity, mass spectrometry for identity), what figure it found, and whether the task number can be verified against the laboratory. A certificate with no verifiable task number is a picture.
