Purity Peptides retains 7.5/10. Its sampled MDX BPC-157 report supplies identity, purity, content and threshold endotoxin evidence; public coverage is selected rather than a complete historical archive.
Evidence summary
Purity Peptides COAs and evidence
The current legacy-domain Trustpilot record is 3.7/5 from 31 reviews, with delivery praise, fulfillment/support complaints and reported replacements. Check the exact lot and seven-day quality-claim terms.
01
Certificate samples and coverage
Purity Peptides publishes MDX BioAnalytical Laboratory PDFs on selected product pages, including BPC-157, GLOW and KLOW. The BPC-157 10mg sample, COA201129/search 201129, lot 260205BP103, was received February 10 and reported February 11, 2026. It confirms identity, 99.74% purity and 10.14mg content, 1.4% above nominal. Endotoxin is printed PASS at a ≤0.05 EU/mL specification, a threshold result rather than a separately quantified reading. No sterility or heavy-metals result appears.
02
Catalog and company
Public report access is partial: other sampled product pages offer COAs on request, and the general COA route explains testing rather than exposing a complete historical library. A current-stock exact-certificate numerator/denominator is unestablished. The retained July 16 snapshot has 79 products and 54 vial-strength rows across 34 canonical compounds. CAD prices and their dated conversion remain distinct from current USD comparison quotes. The store lists 32 Steeles Ave West, Thornhill, Ontario; puritypeptides.ca redirects to puritypeptides.is. PurityPep and HighPurity are separate vendors.
03
Independent buyer experiences
The legacy-domain Trustpilot profile showed 3.7/5 from 31 reviews on October 3. Buyers describe quick delivery and helpful selection; September 29 feedback reports an e-transfer-paid order during a site outage. An updated September 3 account describes receiving MOTS-c 10mg instead of 20mg, followed by a replacement and free item. Other complaints concern missing COAs or unanswered messages; the vendor disputes one account and says batch files were available. These are attributed customer experiences rather than chemical tests.
04
Shipping and quality claims
The stated Canadian shipping rates are 20 CAD regular and 32.99 CAD express, with five to ten and two to four business days of delivery after one to two days of processing. The refund policy, rechecked October 3, gives seven days to report manufacturing or purity concerns with documentation. Approved remedies are replacement or store credit; cash refunds and handling/storage issues are excluded. The owner’s 7.5/10 rating remains, with COA 8.5, reputation 5, transparency 8 and operations 8.
