Vendor Intelligence Report: PurePEPS
Published 13 Jun 2026. 21-page investigative report on who is behind PurePEPS: corporate records, ownership, affiliate networks, and the vendor's lab-testing record. The first 4 pages are free to read on this page.
Researched and published by Finnrick Analytics. Reports draw on corporate records, affiliate-network analysis, and Finnrick's own laboratory testing record; vendors can challenge findings through the formal objections process at finnrick.com/vendor-support/objections.
Executive summary
PurePEPS is an identifiable Indiana-linked peptide vendor, not a throwaway storefront, but its product-quality record is narrow and negative. Across 4 Finnrick lab tests, PurePEPS recorded 0 pass / 4 fail — an overall pass rate of 0%. All covered testing is BPC-157; its Finnrick rating sits at 39.11%, so the signal is poor for that peptide while the rest of the catalog remains untested.
The storefront provides more identity than many gray-market peptide sites: policy pages name Lycan, LLC, Indiana governing law, and a Bloomington PO Box. The unresolved part is registry depth. The report documents why formation date, registered agent, current status, and members/managers could not be confirmed during the run, separating that open lead from the vendor’s own site representations.
The operator trail is more concrete. Records indicate James Rupley is the principal operator, and PurePEPS and sister brand AdvancePeps share his contact channel. A historical Wayback capture also links the brands. That network matters because PurePEPS was captured accepting only Zelle, Venmo, and Cash App, while the sister storefront showed card acceptance.
On product transparency, PurePEPS claims >99% purity on BPC-157, but the captured page had no public COA, batch ID, or third-party lab portal. The report also flags undisclosed or under-disclosed blends and a brand-confusion risk from unrelated Purepeps namesakes, making exact-domain and batch-specific verification central to any buyer diligence.

- COA, blend-disclosure, payment-recourse, and namesake-domain risk analysis
Risk assessment
- BPC-157 quality-control risk — high: BPC-157 is the only Finnrick-tested PurePEPS product; the current database summary records 4 tests, 0 pass / 4 fail, and a 39.11% rating.
- COA and batch-verification risk — high: PurePEPS claims >99% purity but the captured pages did not publish batch-specific COAs, third-party lab links, or a public verification system.
- Undisclosed and untested blend risk — high: 3G-R and 2G-T lack disclosed composition in the supplied product-page record; KLOW 80 discloses components but no independent blend testing was found.
- Payment-recourse risk — high: PurePEPS was captured accepting only Zelle, Venmo, and Cash App, leaving buyers without ordinary credit-card chargeback protection.
- Copycat / brand-confusion risk — medium: Unrelated Purepeps LLC / purepeps.store and purepeps.com.au exist, while no authoritative official-channel, authorized-reseller, or anti-counterfeit verification system was found.
- Operational-scientific oversight risk — medium: Records indicate operator James Rupley’s public background is IN.gov creative/design work; the supplied materials surfaced no scientific or pharmaceutical credentials or separate technical officer.
