What we found at Value Research Labs

Read 31 October 2026 on the vendor's own pages

The certificates hold up at the lab, the archive is open and lot-coded, and the prices are among the lowest we track (BPC-157 10 mg $27.99). What holds it at seven: no company name or address, an 'accredited lab' claim the lab itself does not make, and a checkout with no card option.

Contradiction — the vendor's claims disagree with each other or with the evidence
ContradictionThe homepage says products are 'third-party tested at ISO/IEC 17025 accredited U.S

labs' and the FAQ says 'an accredited U.S. laboratory'. Horizon Analytical, the lab on the certificate we checked, says in its own compliance policy that it does not hold accreditation (31 Oct 2026).

Score history and the caveats

A score only moves when the evidence does
  1. 31 Oct 20267/10 — first assessment (rubric v2): Horizon Analytical certificate confirmed on the lab's verify page (9.91mg on a 10mg label); 40-product lot archive; Trustpilot 4.6 / 451; not awarded: claims-consistent ('ISO/IEC 17025 accredited' vs an unaccredited lab), identity (no entity or address), clean-record (pay-by-bank only, no card processor at checkout)
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.

Value Research Labs: the caveat

No company name or street address anywhere on the site (the terms name 'Value Research Labs' and Georgia law only), so identity is not awarded. The site says testing is done at 'ISO/IEC 17025 accredited U.S. labs', while Horizon Analytical, the lab on the certificate we checked, states in its own policy that it is not accredited — claims-consistent withheld. The store's checkout lists two payment gateways, Link Money (pay-by-bank) and one named 'Argyle', and no card processor, so there is no card dispute route; that costs clean-record. The store domain was registered in June 2026 and the Trustpilot profile (claimed July 2026) is reached through a review site the vendor runs. Measured content 9.91 mg on a 10 mg label, one vial.
