Check notes
A public COA page carries roughly 27 SARM and peptide certificates, all issued by MZ Biolabs (Tucson, AZ) and readable with no account. Newer certificates carry a 'PROOF OF AUTHENTICITY' QR; the decoded link resolves on the lab's own domain (mzbiolabs.com) and returns the matching two-page report, whose second page contains the mass spectrum. Method lines read HPLC-UV-MS or HPLC-MS; several older published images show only the HPLC-UV chromatogram. Published purity figures span 90.2% to 99.97%, with one KPV entry listed at 100.00%. COA lot fields are dates (e.g. 2025-06-16); the retail vial's printed lot format could not be confirmed from public pages. No net-peptide-content or salt-form figure was found on the product page or COA checked. Address 494 Bridgeport Avenue Suite 101-222, Shelton CT; domain registered 2019-08-21.
How to read this
Points are awarded only for a signal we confirmed as a yes. A no means we looked and the signal was not published on the check date. "Not checked" means the signal could not be resolved either way, for example because a storefront was account-gated or no vial label was viewable, and it earns nothing and implies nothing. Confidence is the share of the twelve signals we resolved with a source you can open, so a high score at low confidence is a thinner claim than the same score at full confidence.
