The new peptide-testing brand sells provenance, traceability and “proof, not trust.” Its own corporate provenance is somehow the one thing nobody bothered to put on the website.

ILS let a client upload a vial photo after the order was placed. A dog sailed onto the finalized COA. Then the lab’s “Purity, Identity & Quantitation” report forgot to quantify the vial.

A Melbourne peptide vendor applied to Peptide Critic for a backlink, objected to being reviewed, demanded removal, called us fat, attempted copyright law, apologized, and then watched Victoria issue a serious warning about retatrutide sold online.

The peptide-testing platform wants a marketer to turn lab reports into shitposts while its scoring system turns messy evidence into convenient vendor verdicts.

Peptide Critic tested normal-looking and tiny residue-looking lyophilized pucks from the same Semax/Selank blend.

Peptide Critic partnered with Analytical Formulations Inc. to test how Tirzepatide, MOTS-c, and Mazdutide held up under refrigerated and room-temperature storage over time.

“Retatrutide” batch tested at zero RETA, sending two users to the hospital. Peptide Critic breaks down the factory raid, AFI test results, community warnings, and the dangers of gray-market peptides.

Grey market peptides are growing in popularity, but safe research practices are essential. Learn about transparency, vendor testing, and lab protocols that protect research integrity.

Learn why third-party peptide testing is essential for research reliability. Discover trusted labs like Janoshik, Freedom Labs, and Colmaric, and why vendor COAs alone aren’t enough.
