Customers

What the research says

Melanotan II is a synthetic cyclic heptapeptide analogue of α-melanocyte-stimulating hormone (α-MSH). It activates several melanocortin receptors (MC1R, MC3R and MC4R), which is why it was studied for skin pigmentation and why its effects reach beyond the skin. It came out of research at the University of Arizona in the 1980s and 1990s; bremelanotide (PT-141) is a later compound from the same line of work. Melanotan II has not received FDA approval. 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.
