Aavant Chemistry is facing new reports of hair and cracked vials while China-sourced peptide COAs show mislabeled, failed, and mystery products across the gray market.

What started as a simple order test turned into a multi-week case study in delayed fulfillment, missing product, weird communication, surprise refunds, surprise shipping, and lab results that somehow made the bacteriostatic water the hero of the story.

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

Multi-lab retatrutide testing from AFI, Janoshik, TrustPointe, Freedom, and Vanguard shows why peptide purity and mass results can vary between labs.

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.
