Sixty seconds, and you do not need a seller picked to use them. Answer what you can. Anything you cannot answer is already telling you something, and the page then shows what a passing answer looks like on each one.

Janoshik / 73 peptide tests / 215 dollars
Have someone in mind? Answer for them. If you do not, answer for the last site you looked at, or just read the seven and see what a real one has to show you. Not sure counts as a no, and that is the point.
The same seven checks, with what a real answer looks like beside each one, so you can see where your own answers came up short. Every one of these is checkable before you create an account anywhere, and we sell nothing.

Four fields turn a report from a claim into evidence: the laboratory's name at the top, a client field, a batch, and a purity figure carrying decimals. Two sellers here publish exactly that, and both can be checked at the laboratory rather than at the shop.
Crystal Peptides, Retatrutide 20mg. Janoshik, task #163572,
client Crystal Peptides EU, batch RT6423CP, purity
99.744%, amount 22.43 mg. Key THC88ILYEN8S at
janoshik.com/verify/.
American Peptides, Retatrutide 20mg. Bioviridian Inc., code
COA7599, lot RETA20-0803, purity 99.79%, amount
20.22 mg, endotoxin <0.05 EU/mL, heavy metals
<0.01 ppm. Checkable at bioviridians.com/coa-search.html.
Neither document was written by us, and neither can be edited by the seller after the fact. That is the whole point of the check.
Contamination is a separate panel with its own report. Endotoxin, heavy metals and sterility look at what is around the molecule, not at what the molecule is, and they are not what the seven checks ask about. They are no longer exotic either: Crystal Peptides publishes 18 sterility, 18 endotoxin and 19 heavy metal reports. American Peptides carries endotoxin and heavy metals on the certificate itself and publishes no sterility result at all, while arguing for sterility testing in its own banner on every page. Ask any supplier which of the three they run, and whether the results sit on the certificate for your lot.
Pick a research area and we will open the right shelf instead of the whole catalogue.
One page, seven checks, run it against any supplier, with what a pass looks like written beside each one.
