Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Lost Coast Aminos. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at Lost Coast Aminos
Read 10 October 2026 on the vendor's own pages
The cheapest TB-500 in our index, sold by a company with no name, no address, no named laboratory, and no card processor. The Trustpilot record is positive, but 37 reviews is not a safety net, and the payment methods mean that if a vial is wrong there is no one to dispute the charge with. Price is not the reason to buy here; it is the reason to be careful.

6 Sep 20265/10 — re-issued under rubric v2 (was 2/8); not awarded: lab-hosted, review-base, claims-consistent, identity, clean-record
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.
Lost Coast Aminos: the caveat
The lab (BTLabs, West Palm Beach) appears only on the certificate image, never in page text; the certificate (lot LCA0526BC20) reports 20.4mg vs 20mg label. Payment only by Zelle, Cash App or a manual card invoice — no chargeback protection. No legal entity, address or phone. Legal pages contradict each other (18+ vs 21+, 24h vs 48h damage window) and BPC-157 showed different price ranges on the shop page and its product page the same day. GLP products sold as LCA-SM / LCA-T2 / LCA-R3 with no stated identity. 37 reviews.
