Vendor's own wordPublishes 2 of 6 disclosure signals — 1 document-backed, 1 vendor-stated · checked 17 Aug 2026

Vendor-supplied · Not verified by PeptideBase

What this vendor publishes about itself, repeated here. Disclosure is not verification; only independent lab results change that.

5 certificates on file, all self-published by the vendor. Median purity 99.81%, against 99.66% across all 1,295 certificates we score. Four of five compounds test at or above their market median. The exception is a Tesamorelin lot at 99.19% — 0.25 points below the 99.44% median for that compound.

COAs the vendor posted on their own site.

Recorded for completeness. A self-published document doesn't count as confirmed on its own — the document is real, the chain of custody isn't independent.
