Peptaura
Marketplace · Stacked Score does not apply
Multi-supplier platform
Peptaura aggregates independent international suppliers under a single checkout, escrow, and dispute-mediation layer. Stacked surfaces it as a directory entry but does not assign a Stacked Score — our scoring methodology is built around single-storefront retail vendors, and applying it to a platform that brokers across multiple suppliers would be dishonest. Per-supplier prices are also intentionally not indexed in our price tracker, since manufacturer-tier $/mg is not directly comparable to retail vendor pricing. Read the methodology note for the full distinction.

Pros & Cons
Pros
- Marketplace structure — 8+ international suppliers per popular compound (Retatrutide, Tirzepatide, BPC-157, Tesamorelin, GHK-Cu, MOTS-C and more), with side-by-side supplier comparison on a single product page
- Escrow + dispute-mediation layer that retail vendors don't offer — funds are held until the supplier ships and the buyer confirms receipt
- Centralized COA repository — supplier-uploaded certificates of analysis stored on the platform rather than scattered across DMs and per-vendor PDF pages
- Aggregate transaction volume gives the platform leverage to enforce stricter QC, supplier vetting, and shipping discipline than individual buyers can negotiate alone
- Single checkout across multiple suppliers — researchers stacking compounds across labs avoid the operational overhead of separate orders, separate payments, and separate shipping windows
Cons
- Manufacturer-tier pricing comes with manufacturer-tier risk — international shipping (sometimes 7+ business days transit), customs handling, and batch-to-batch variance the platform itself flags as the primary risk
- Peptaura does not test compounds in-house — COAs are uploaded by the suppliers themselves, which is a weaker assurance than a retail vendor sending a per-vial third-party certificate from Janoshik or Finnrick
- No Stacked Score — the Trust Score methodology applies to retail vendors that own inventory, ship under a single brand, and process chargeback-protected payments; marketplaces sit outside that frame
- Crypto / escrow checkout instead of standard credit-card chargeback rails — buyers who rely on card-issuer dispute protection should weigh that trade-off carefully
- Newer platform — fewer years of community history and vendor reputation than the established retail storefronts in this directory

Testing Methodology
Peptaura does not test compounds in-house. Each listed supplier uploads its own certificates of analysis to the platform's COA repository, and the platform states intent to introduce random checkpoint third-party testing through Finnrick as the marketplace grows. Buyers retain full responsibility for independent batch verification (Finnrick, Janoshik, or Chromate are the labs Peptaura recommends for self-testing).
