Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Global 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 Global Aminos
Read 5 September 2026 on the vendor's own pages
Global Aminos competes on price and delivers on it — the BPC-157 and TB-500 figures are close to the floor of our index. Everything a cautious buyer would want next is absent: a named lab, a readable certificate, a company name. The 'two independent laboratories' line cannot be checked because neither laboratory is identified.

Could not verify · flags
?Which laboratory tests the products — the homepage says 'third party tested in USA labs' and 'two independent laboratories' but no lab is named on any page.
?Lot matching and net content — the certificate is a JPEG on the vendor's server (filename Glob2604060054); we could not read a lab name or a measured-mass line from it.
?Who runs it — no legal entity, address or phone on About, Contact or Terms.
?What GLP-S (1) / GLP-T (2) / GLP-R (3) contain — no CAS or identity is stated.
!One homepage banner says 'Third Party Tested in USA Labs'; another tile on the same page says 'two independent laboratories, including one USA-based facility'.
!The GLP-T (2) page describes the product as a 'GLP and GIP antagonist' — the tirzepatide class it is coded after is an agonist.
!NAD+ 500mg price moved from $37.19 to $52.69 between two reads on the same day — treat prices here as volatile.

Where Global Aminos ranks by compound
Global Aminos appears in 3 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-067/10 — re-issued under rubric v2 (was 2/8); not awarded: review-base, claims-consistent, identity
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.
Global Aminos: the caveat
The lab (Freedom Diagnostics) appears only on the certificate image, never in page text; the certificate carries a search code (Glob2604060054) and reports 10.31mg vs 10mg label. No legal entity, address or phone. GLP products sold as GLP-S (1) / GLP-T (2) / GLP-R (3) with no stated identity, and one page describes its GLP product as an 'antagonist'. 38 reviews.
