VENDOR MATCHUP · AUDITED

Amino Club vs BioTech Peptides

Two audits, side by side. Composite, subscores, shipping, payment, coupons. BioTech Peptides takes the higher composite this cycle.

Composite score

67
OF 100
VENDOR AUDIT

Amino Club

A large, fast-growing US shop, selling since January 2026 from a New Jersey address, with the most complete certificate set we have read: 112 lot-level certificates cover all 51 products, and every one we checked against the lab's own records matched. Identity is tested by HPLC retention time only, no buyer has published an independent test, the GLP-1s are sold under code names, refunds are refused except for transit damage, and the site names no legal entity. Prices sit well below our index on most staples. Public-data audit, no first-hand order, 67/100.

VENDOR AUDIT

BioTech Peptides

Established US-domestic peptide synthesizer with a substantial catalog and same-day shipping. It does publish per-batch COAs - 84 of 89 product pages carry a downloadable certificate, most of them MZ Biolabs reports naming the client and lot, with a set of older SKUs on a lab-unnamed template. Public-data audit; we have placed no test order.
