Verdict: Purgo Labs, on the evidence: 10/10 rubric points against 7/10. Amino Science Labs is stronger on 2 points listed below.
Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Amino Science Labs. 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.
No compound-and-size pair with dated prices from both vendors yet. Each vendor's readings are on the price index.
Better certificates than most — actually hosted at the lab — from a six-month-old company whose Terms say you pay by Cash App or Zelle with no refunds. The documentation earns its points; the payment terms and seven reviews are why it stops at seven.
