ZZtai Peptide is a China-based vendor selling to both retail and bulk customers. The catalogue is small, and the site currently has no third-party COA coverage for any of its products. Community feedback is sparse—around ten mentions from a single source—and leans mixed on product quality and testing transparency, with one positive note on shipping experience. The limited sample makes it difficult to assess consistency or reliability.

Testing coverage
We hold lab certificates for this vendor, but none of them correspond to a product currently in their catalogue — so we cannot confirm what is in any vial you could actually buy. Testing scores zero until that mapping exists. This one is on us as much as them.
