What we found at Peptide Giants

Read 10 October 2026 on the vendor's own pages

Smaller review base than others in this batch, but the certificate chain is the real thing — named labs, lab-hosted reports, dated batch history per product — and the company discloses more corporate identity than any other vendor we researched this round.

Score history and the caveats

A score only moves when the evidence does
  1. 5 Sep 20267/8 — first assessment under rubric v1
  2. 6 Sep 202610/10 — re-issued under rubric v2 (was 7/8); not awarded: none
Purgo Labs: the caveat

Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.

Peptide Giants: the caveat

Small review base (65 on Trustpilot, 26 Sep 2026). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT.
