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 audit; we have placed no test order.
Lot-numbered certificates on its product pages, none in our lab mirrors; Finnrick passes 7 of 22 samples; an Ohio pharmacy-board case names it as a clinic's unlicensed DSIP source. Public-data audit, no first-hand order, 47/100.
