Supplier documentation profile
PS Peptides
PS Peptides publishes a large, searchable certificate library with product- and strength-specific records. Sampled current BPC-157 records identify the laboratory, test ID, supplier batch ID, HPLC purity, measured mass, heavy-metals screen, endotoxin result, sterility result, and fentanyl screen. Molecular-identity detail and laboratory accreditation still require independent verification beyond the supplier's presentation.

Procurement details
Business policies not yet documented
PDD has not yet preserved dated, directly reviewable records for this supplier's ship-from location, regions served, processing time, free-shipping threshold, payment methods, or refund and replacement policy. We do not infer those details from a storefront location or checkout availability.
This section will expand into field-level records as eligible supplier policies are documented.
Evidence ledger
What the reviewed records support
Evidence and COA records last reviewed September 10, 2026. Missing documentation remains visible and is not converted into a negative claim.
| Review field | State | Finding and limitation | Basis |
|---|---|---|---|
| Public COA access | Documented | A no-login certificate library exposes current and historical product- and strength-specific reports, including separate analytical and contamination-testing records. | Certifications library + sampled BPC-157 records |
| Lot traceability | Documented | Sampled reports identify the product, nominal vial mass, supplier batch ID, test ID, and order date. A received-vial-to-report match remains a separate physical verification step. | Sampled BPC-157 5 mg and 10 mg reports |
| Laboratory provenance | Documented | Sampled reports name North American Diagnostics and provide its website, address, test identifier, and report administrator. The laboratory's claimed accreditation and relevant scope have not yet been independently confirmed. | Sampled current reports |
| Chromatographic purity | Documented | Sampled BPC-157 reports identify HPLC with UV detection and publish 99.92% and 99.90% purity results for the reviewed 5 mg and 10 mg records. | June 2026 BPC-157 COAs |
| Molecular identity | Supplier-reported | The sampled COAs state that HPLC was coupled with mass spectrometry and label a mass-identification result, but the extracted one-page records do not expose expected-versus-observed mass values or spectra. | June 2026 BPC-157 COAs |
| Measured quantity | Documented | The reviewed BPC-157 reports publish measured content separately from purity: 5.03 mg for the 5 mg record and 9.69 mg for the 10 mg record. | June 2026 BPC-157 COAs |
| Sterility testing | Documented | A sampled August 2026 BPC-157 report identifies USP <71> direct inoculation and reports no growth for the listed supplier batch. | BPC-157 5 mg sterility report |
| Endotoxin testing | Documented | A sampled batch-specific report identifies a kinetic chromogenic LAL method and reports less than 5 EU per vial. | BPC-157 5 mg endotoxin report |
| Contamination testing | Documented | Sampled reports publish an ICP-MS screen for lead, arsenic, cadmium, and mercury and a separate LC-MS/MS fentanyl screen for the same listed BPC-157 batch. | BPC-157 5 mg heavy-metals and fentanyl reports |
| Research-use positioning | Documented | The homepage, shop, terms, and sampled product pages state that products are for qualified laboratory and in-vitro research and not for human or animal consumption. | Homepage + shop + terms + sampled product page |
| Marketing consistency | Contradicted | Research-only notices coexist with dosing calculators, reconstitution guidance, injection-route discussion, consumer-style bundles, and protocol language. PDD does not reproduce or endorse those human-use-adjacent materials. | Homepage + sampled BPC-157 and retatrutide pages |

Evidence definitions
Documented
Connected to a directly reviewable public record.
Supplier-reported
Stated by the supplier but not independently confirmed.
Unresolved
The records reviewed do not support a conclusion either way.
Contradicted
Available records or statements materially disagree.
Open verification work
- Independently verify the issuing laboratory, its claimed accreditation, and the scope covering each reported method.
- Match a current catalog product, supplier batch record, and physical-vial identifier.
- Review expected and observed mass-spectrometry values or spectra rather than relying on a mass-identification label alone.
- Repeat the complete-panel review across representative peptides and finished blends; one BPC-157 batch does not establish universal coverage.
- Keep PDD referral placement separated from the supplier's dosing, injection-route, and protocol content.
