Peptide Pros transparency score
Computed at build time from the twelve signals in the published rubric, using only evidence recorded on July 21, 2026. Every row below links the page or document the value came from, so you can re-run the check yourself.

Check notes
Site loads (WordPress/WooCommerce, redirects to www). A public /coa-reports/ page links 17 COA PDFs plus COA images covering roughly 20 compounds. Seven PDFs were downloaded and read: all are on MZ Biolabs letterhead (1635 E 18th St, Tucson AZ 85719), client Peptide Pros, method 'Mass Spectrometry and UV' with 'Peak identity confirmed by mass spectrum evaluation'. Lots and purities read: BPC-157 lot AF98762213 100.0%, Sermorelin lot AF88932011 100.0%, BPC-157/TB-500 lot AF98799011 99.1%, CJC-1295 lot AF21220321 99.5%, Ipamorelin lot AF78890211 99.0%, Melanotan 2 99.0%, MK-677 99.77% - so most figures sit in the 99% band while two of seven read exactly 100.0%. The BPC-157 product page links its own COA PDF; the Tesamorelin 5mg page carries no COA, so library coverage is partial against a catalogue of 47 peptides and 36 SARMs/liquids. Reports carry lot numbers but no accession or QR to a lab portal; the only embedded link points back to the vendor's own product page. Analysis dates on the reports checked are 2021-2022. Secure Ordering lists e-check, Bitcoin, and check/money order. WHOIS creation date 2014-02-19; support line 1-888-391-1312 published; no street address published.
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.
