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.

Can it be used in humans?

Only after a physician has reviewed your intake, and only as the guidance issued with your order sets out. None of these compounds is approved by the FDA or ANMAT for that use — which is precisely why the review exists, and why no protocol is published here for anyone to apply on their own.

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.

Why does PeptoClinic publish no prices?

Because there is no single price. Cost turns on quantity, vial size, the documentation the programme needs and the dispatch route. Each compound is quoted in writing after a free, no-obligation technical consultation, normally within one business day.

Physician-reviewed supply

Compounds on this site are supplied after an intake that a physician reviews one by one. None of them has been evaluated or approved by the FDA, ANMAT or any equivalent authority for the use it is requested for, and nothing on this page is a recommendation to start one on your own judgement. Whether a compound suits a given person is the reviewing physician's decision.
