Testing and trust

Third-party COA

Yes - third party via Bioviridian

Testing lab

Bioviridian Inc.

Methods

HPLC + MS (LC-MS/MALDI-MS, plus ICP-MS for heavy metals) via Bioviridian Inc., College Station, TX (bioviridians.com). 48 batch COAs published across the catalog as of Aug 2026, all reading "Pass". Bioviridian is a real, named, independently-operated lab with its own public COA-search portal (a batch/COA number can be looked up directly at bioviridians.com) - the identity was confirmed on the lab's own site, not just the vendor's claim, matching this project's standard. Bioviridian states its own accreditation is "underway" - not yet ISO 17025 accredited as of Aug 2026. The COA search is a JS-driven form; an individual batch number could not be cross-verified through an automated fetch, so batch-level authenticity rests on the lab being real and named rather than on a document-by-document check.

Reputation

Community reputation

No reliable third-party review data found. An earlier automated search summary reported a 4.7/5 Trustpilot score with 36 reviews, but that could not be reproduced: direct fetches of the actual Trustpilot pages (uk., www., and ca. subdomains) for peaklabpeptides.com all show "This profile has been removed. The business you're trying to find goes against our guidelines and is no longer visible on Trustpilot." The earlier figure likely came from a search-result summary that conflated this vendor with a similarly-named but different store (peakpeptides.shop / peakpeptide.com both surfaced in the same search). No Reddit or independent-forum discussion found either way. Not yet reviewed on Peptul.
