Testing laboratory

Horizon Analytical

Unverified lab

We could not confirm this is a real, independent laboratory. Its certificates are shown for transparency only and never counted as independent evidence.

Why: We could not confirm Horizon Analytical is a real, independent lab. Circumstantial public records tie it to a peptide-vendor group (a shared suite address with the DIRECT PEPTIDES trademark owner; a domain registered the day after that trademark filing). No registered lab entity or accreditation was found. We do not assert it is fake or vendor-owned — only that its independence is not established.

Reputation & incidents

A live COA-issuing operation with a verification portal, but its independence from the vendors it serves is unestablished, with documented circumstantial affiliation red flags.
