Nationwide Peptides

Executive Summary

Certificate of Analysis (COA) Practices

Status: COA ✓ (third-party lab tested)

COA URL: https://www.nationwidepeptides.com/coa/

Notes: Public COA library at /coa/ with no login. 63 reports, all issued by Freedom Diagnostics Testing (client: National Science Labs, LLC) — a recognized third-party lab that also supplies COAs for several vendors rated highly on this site — covering HPLC-UV purity, LC-MS identity and net peptide content. PeptidePrices verified three reports against the lab's own public registry, which is open and server-queryable: BPC-157 5mg (accession 2601230002, 98.824%), GLP-3R 5mg (2606100514, 99.70%) and BPC-157 10mg (2606300377, 99.34%, lot V4707523469). The lab-hosted PDFs are MD5-identical to the vendor-hosted copies, so those documents are not altered. GLP codenames were decoded from the molecular formula printed in each COA: GLP-1S = C187H291N45O59 = Semaglutide, GLP-2T = C225H348N48O68 = Tirzepatide, GLP-3R = C221H342N46O68 = Retatrutide. PeptidePrices reviewed the published library. ⚠️ Four COAs read 'Identity: Failed' and one reads 76.11% purity, and all five products remain on sale: P21 5mg (no analyte detected), ARA-290 10mg (no analyte detected), ADAMAX 5mg (LC-MS detected retatrutide), AHK-CU 50mg (LC-MS detected GHK-Cu) and AOD9604 5mg (76.11%, 4.16mg on a 5mg label). No superseding COA exists for any of them. The /coa/ index table shows Product, Purity, Batch and Test Date but has no Identity column, so AHK-CU 50mg appears there as a clean 99.69%. Four of the five are not on the index at all. ⚠️ 28 of 73 products have no COA, against an FAQ that claims a COA on every product page and a QR code that does not exist. ⚠️ The panel is purity, identity and net content only — no endotoxin, sterility or heavy-metals testing appears on any report, against an About page that claims endotoxin testing. Note the 'Nati' search-code prefix is the first four letters of the company name and is not unique to this vendor. PeptidePrices is an affiliate partner (10% commission, code peptideprices for 10% off) — disclosed per FTC; affiliate status does not influence the rating.

Rating Methodology

PeptidePrices rates vendors on a 1–10 scale using a transparent, weighted rubric:

• 40% COA practices — named third-party lab, batch-to-vial linkage, public on-site publication, testing breadth (HPLC purity, mass-spec identity, endotoxin, sterility, heavy metals)
• 20% Community reputation — Trustpilot weighted by review volume, Reddit/forum sentiment, documented red flags
• 20% Transparency — physical address, company age, ownership disclosure, contact info, domain age, return policy
• 20% Operations — shipping speed, customer-service responsiveness, payment flexibility, and dispute handling; affiliate-program performance is not scored

PeptidePrices is independent. No vendor has paid to increase their score. Full methodology at peptideprices.net/trust.
