Two audits, side by side. Composite, subscores, shipping, payment, coupons. BioTech Peptides takes the higher composite this cycle.
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 preview; first-hand audit pending.
New US shop on a WooCommerce storefront, domain registered April 2026, selling 22 research compounds with unusually complete certificates: full panels on 17 of 21 products, mostly from Optiq Health Labs, a real California lab. None of it is in our independent mirrors, two certificates come from an unverifiable lab, pricing runs well above our index on several staples, and payment is Venmo or Zelle only. Retatrutide is sold under its real name and we found no FDA action. Public-data audit, no first-hand order, 64/100.
