How This File Was Assembled

What checked means here

Every claim in the file carries one of four verification levels, and only these four:

• read the live page;
• downloaded the file and confirmed its type;
• listed on the page, not opened by us;
• stated by the company, not tested by us.

The level is the honest ceiling of the check. A file confirmed by type is not the same as a file read line by line, and the level says which one happened.

What was opened, and what was only listed

Five files were downloaded and confirmed by type: three certificate PDFs, for Retatrutide, BPC-157 and GHK-Cu, and two Janoshik report images, for Retatrutide and BPC-157. Fourteen certificate PDFs and four second-laboratory reports are published and linked in total. The files beyond the five were not opened by this site.

The wording rules we hold ourselves to

• The testing laboratory is written in full every time: aligned to ISO/IEC 17025:2017, not itself accredited. We never write that the laboratory holds the standard, because the paperwork does not say that.
• Any block naming the partner's License to Operate or SEC registration carries, in that same block, that these are held by the partner and not by Peptara Labs, that neither is an approval of any product, that the License to Operate is a facility license for a cosmetic trader, and that it does not mean any peptide sold has been evaluated by the FDA for safety or effectiveness.
• The two rating figures are never merged. We publish them as two.
• We issue no rating of our own. This site earns a commission, so a score from us would be worth nothing.
• A named third party is reported only as a different domain string. We make no accusation and we link none of them.
• Amounts and prices stay off the page. We link the seller's page rather than restate an offer.

One example of a seller disclosing its own position

Peptara Labs publishes a comparison page that lists itself in its own table and states it wrote the rubric, a five-point rubric on what a seller publishes. We cite that as an example of a seller disclosing its own position. We did not adopt its rubric as our method. It sits on the comparison page Peptara Labs publishes.

Dates and corrections

Every page here was read on 2026-09-01, and the file carries that date. When a source moves, the affected line is re-read and the stamp is reset to the day the page was read again.
