EXECUTIVE SUMMARY
A large public certification library with strong batch-level detail.
PSPeptides maintains a large, searchable public certification library with current and older batch-specific reports. PSR verified a July 2026 Retatrutide 40mg report from North American Diagnostics containing Test ID PSP-0029123, client ProSupply Peptides / pspeptides.com, Batch ID PSP-06262026RT, HPLC with UV detection coupled with mass spectrometry, 99.96% purity, and 39.76mg measured content. Public pages clearly display product quantities, prices, availability, testing claims, contact email, support hours, terms, refund conditions, and research-use restrictions. The primary limitation is that legal-entity, street-address, ownership, and laboratory-accreditation details are not consistently displayed across the main public pages. Supplier claims about cGMP-guided US manufacturing are treated as supplier-stated, not independently verified.
01 / DOCUMENTATION REVIEW
Documentation Quality
OBSERVED PUBLIC DOCUMENTATION
Public searchable certification library · Current and older reports organized by product and strength · Product pages with quantities, prices, and availability · Contact email and support hours · Terms and refund conditions · Research-use restrictions
OPEN QUESTIONS
Consistent public legal-entity details · Street address · Ownership disclosure · Laboratory-accreditation details · Independent confirmation of cGMP-guided US manufacturing claims
PSR OBSERVATION
PSPeptides makes batch-specific documentation broadly accessible through a searchable public library. PSR observed current and older reports plus clear policy and product information, while treating supplier manufacturing statements and unlisted corporate or accreditation details as supplier-stated or not determined.
02 / TESTING EVIDENCE
PSR reviewed PSPeptides’ public certification library, a July 2026 Retatrutide 40mg report, product listings, and policy pages. The library is organized by product and strength and includes current and older reports. The verified sample names North American Diagnostics, Test ID PSP-0029123, client ProSupply Peptides / pspeptides.com, Batch ID PSP-06262026RT, HPLC with UV detection coupled with mass spectrometry, 99.96% purity, and 39.76mg measured content. PSPeptides also describes HPLC, mass spectrometry, heavy metals, endotoxin, sterility, and fentanyl screening. PSR did not independently validate laboratory accreditation, raw data, complete catalog-wide coverage, safety, efficacy, regulatory approval, or suitability for human use.

CATALOG COVERAGE / NOT DETERMINED
Full Catalog Coverage
PSPeptides maintains a large public certification library with current and older batch-specific reports. PSR verified one July 2026 Retatrutide 40mg report, but did not independently establish complete current coverage across every product or batch.
These observations apply only to the specific submitted samples represented by the reviewed certificates and should not be generalized to every supplier product or batch.
04 / LOT TRACEABILITY
Lot Traceability
The verified certificate identifies Batch ID PSP-06262026RT and is presented within a public certification library organized by product and strength. This supports strong document-level lot traceability. PSR has not independently observed the full chain of custody from manufacturing through laboratory submission and customer inventory.
05 / PRICING VISIBILITY

PSR ASSESSMENT
Preliminary PSR Transparency Score: 95 / 100 — Excellent Transparency
PSPeptides provides excellent public transparency through a large searchable certification library, current and older batch-specific reports, and clear product and policy information. The observed July 2026 Retatrutide 40mg report includes laboratory, test ID, client, batch, method, purity, and measured-content detail. These features support a 95/100 preliminary transparency assessment. PSR does not treat supplier-hosted reports or stated testing and manufacturing practices as proof of safety, efficacy, regulatory approval, complete chain of custody, or suitability for human use. Legal-entity, street-address, ownership, laboratory-accreditation, raw-data, and catalog-wide coverage questions require continued review.
