Supplier documentation profile

NextGenPeps

NextGenPeps operates separate U.S. and Canadian research-material storefronts. The Canadian site lists CAD pricing, Canadian-held inventory and domestic fulfillment, while both storefronts provide searchable public COA access. Public records name Janoshik Analytical and BioRegen, list product strengths, test dates and purity results, and link to available reports. Selected records also include endotoxin results. The remaining due-diligence questions are current-inventory lot matching, consistent molecular-identity and measured-quantity coverage, and independent confirmation of BioRegen's credentials and methods.

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 24, 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 COA library lists dozens of products and links directly to available reports. It can be searched by product, size, batch, laboratory, purity, and endotoxin terms.	Public COA library
Lot traceability	Unresolved	The library connects reports to product names and strengths, but PDD has not yet confirmed that a report identifier maps consistently to the lot printed on current inventory and delivered vials.	COA library + sampled product records
Laboratory provenance	Documented	The public library names Janoshik Analytical and BioRegen. Sampled Janoshik records include direct verification URLs; BioRegen's credentials and analytical scope remain to be independently confirmed.	COA library + sampled Janoshik reports
Chromatographic purity	Documented	The library publishes product- and strength-specific purity results with laboratory names and test dates. Sampled entries include BPC-157, GHK-Cu, MOTS-C, Semax, Sermorelin, and Tesamorelin.	COA library + sampled reports

Public COA access

Documented

A no-login COA library lists dozens of products and links directly to available reports. It can be searched by product, size, batch, laboratory, purity, and endotoxin terms.

Basis: Public COA library

Lot traceability

Unresolved

The library connects reports to product names and strengths, but PDD has not yet confirmed that a report identifier maps consistently to the lot printed on current inventory and delivered vials.

Basis: COA library + sampled product records

Laboratory provenance

Documented

The public library names Janoshik Analytical and BioRegen. Sampled Janoshik records include direct verification URLs; BioRegen's credentials and analytical scope remain to be independently confirmed.

Basis: COA library + sampled Janoshik reports

Chromatographic purity

Documented

The library publishes product- and strength-specific purity results with laboratory names and test dates. Sampled entries include BPC-157, GHK-Cu, MOTS-C, Semax, Sermorelin, and Tesamorelin.

Basis: COA library + sampled reports

Molecular identity

Supplier-reported

NextGenPeps says testing supports identity and purity, but PDD has not yet established consistent report-level identity results and acceptance criteria across current catalog lots.

Basis: About page + product pages + sampled reports

Measured quantity

Unresolved

Vial strengths and potency language are published, but consistent independent quantitative content results were not established across the sampled current records.

Basis: COA library + sampled product records

Sterility testing

Unresolved

Consistent lot-matched sterility results were not located in the public records reviewed.

Basis: COA library + sampled reports

Endotoxin testing

Documented

Selected Janoshik entries link separate endotoxin reports, including records for BPC-157, CJC-1295 with DAC, GHK-Cu, Melanotan II, Semax, and Sermorelin. This coverage is not shown for every listed product or lot.

Basis: COA library + sampled endotoxin reports

Research-use positioning

Documented

The compliance statement and terms restrict products to qualified in-vitro laboratory research and exclude human, veterinary, clinical, diagnostic, therapeutic, cosmetic, and dietary use.

Basis: Compliance statement + terms + sampled product pages

Marketing consistency

Unresolved

Formal policies use a clear research-only boundary, while sampled storefront pages contain consumer-style ratings and reviews and some broader application language. Referral destinations remain subject to page-level review under PDD's stricter standard.

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

Confirm how report identifiers map to the lot printed on current inventory and delivered vials.
Verify BioRegen's legal identity, credentials, methods, and analytical scope independently.
Record molecular-identity and measured-quantity coverage by current catalog lot.
Ask whether lot-matched sterility results are available and whether endotoxin coverage will expand beyond selected records.
Confirm the affiliate commission rate, attribution window, qualifying-order rules, and any customer discount code in writing.
Continue page-level review of referral destinations for consistency with PDD's research-only boundary.
