Disclosure: Purgo Labs is our affiliate partner; we earn nothing from FelixChem (Felix Chemical Supply). 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 FelixChem (Felix Chemical Supply)
Read 11 September 2026 on the vendor's own pages
A registration wall in front of the catalog and no public identity leave almost nothing to verify. The product feed shows ordinary prices; nothing shows what is in the vial or who is selling it.

Certificates we opened at FelixChem (Felix Chemical Supply)
Where FelixChem (Felix Chemical Supply) ranks by compound
FelixChem (Felix Chemical Supply) appears in 5 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-112/10 — first assessment (rubric v2); registration wall — testing and identity unverifiable
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
FelixChem (Felix Chemical Supply): the caveat
Product pages redirect to a registration landing page, so certificates, lab name and identity are invisible without an account. Trustpilot shows 3.5 across 2 reviews, unclaimed. No legal entity or address found; a third-party review names 'Chem-LLC' but we could not confirm it. GLP-class products are sold as Peptide-S, Peptide-T and Peptide-R with no stated identity, so they are excluded from our Price Index.
