Direct answer
Is PS Peptides legit?
PS Peptides earns 9/10. The October 4 review reconciled 195 report identities across 660 complete files: 190 exact lab-confirmed North American Diagnostics reports and five vendor-named Vanguard reports retained with neutral file-reviewed status. Current strength tabs show 96 primary reports; 99 historical identities remain inspectable. Five current GLP-3R tabs pair new Vanguard primary lots with older NAD supplemental panels from different lots, which stay separate. Trustpilot showed 4.3/5 from 204 exact-domain reviews on October 3, 2026.

PS Peptides has a complete retained archive, 190 lab-confirmed NAD report identities, five clearly scoped file-reviewed Vanguard reports, confirmed printed vendor attribution, a meaningful independent review record, and a working multi-method checkout.
The evidence supports 9/10. Exact product matches stay tied to current matching reports. Missing NAD analysis dates, the five unauthenticated Vanguard records, and different-lot supplemental panels remain separate COA limitations.
01
Complete certificate archive
Reviewed October 4, 2026: PS Peptides’ finite archive declares 543 distinct PDF URLs across 59 product cards and 96 current strength tabs. The merged library preserves 195 report identities and all 660 complete one-page files, including older certificates no longer linked in current tabs. North American Diagnostics accounts for 190 lab-confirmed report identities; all 373 newly retained NAD PDFs exactly match their official PDFs. Five new Vanguard primary reports are vendor-named and file-reviewed, without an authenticated specific official record. Current tabs supply 96 primary reports; the remaining 99 are historical. Same-ID NAD bundles keep identity, HPLC purity/content, ICP-MS heavy metals, LAL endotoxin, USP <71> sterility and LC-MS/MS/immunoassay fentanyl pages together. Tested panels are counted once per report identity, not as separate certificates. Five current GLP-3 primary Vanguard lots are displayed beside older NAD supplementary tests from different lots; those panels remain with their original reports. Representative SNAP-8 10 mg report NAD-0037958 records 10.14 mg at 99.90% purity, while Adipotide 5 mg NAD-0037960 records 4.92 mg at 99.93%. NAD’s printed Date Ordered stays separate from a test or issue date. Vial endotoxin reports show <5 EU/vial; the acetic-acid solution instead shows <0.5 EU/mL. Metals reports state Not Detected for Pb, As, Cd and Hg without numerical reporting limits.
02
Independent review record
The exact-domain Trustpilot profile lists 4.3/5 from 204 reviews on October 3, 2026. Readable purchasers praise delivery, packaging and responses to questions; lower-rated accounts describe shipping-label creation before carrier dispatch and delays. These service accounts remain separate from the laboratory record. ProSupply's public legal name and Paramus mailing address allow the customer record to be attributed to the same storefront; the address is a UPS mailbox rather than a lab.
03
Exact catalog coverage
The PeptidePrices comparison catalog contains 29 active PS Peptides rows across 19 canonical compounds. The October 4 source review found 96 current primary reports across the wider merchant archive. Exact matches require the same vendor, canonical compound, strength and unit; historical reports stay in the library. The GLP-3R 5 mg/10 mg/20 mg/30 mg/40 mg tabs now display five Vanguard primary reports for September lots beside older North American Diagnostics supplementary panels from different lots. The Vanguard files cover identity, purity and measured quantity; the old NAD panels are not assigned to those new lots. BPC-157 10 mg report NAD-0036045 retains its same-lot identity, purity, content, endotoxin, metals, sterility and newly captured fentanyl pages.

BPC-1575-test panelCOA available North American Diagnostics · Report strength 10mg · Testing ordered Aug 28, 2026
Numbered annotations explain each laboratory report’s identity, measured results and testing scope. Open a report to read the complete analysis and original files.
All five original PDFs share this test ID, batch and product. The printed date is Date Ordered (2026-08-28); no issue or analysis date is invented.
Exact formulation
500 mg reported · lyophilized puck · one 10 mL vial
Vial size describes the submitted container, not a reconstitution concentration.
Purity
99.90% HPLC purity
The core certificate prints no separate numerical purity acceptance limit. Do not infer a universal cutoff from its high percentage.
Identity
NAD+ mass identification
The core sheet names HPLC with UV detection coupled with mass spectrometry and identifies the reported compound.
Content versus reported amount
510.24 mg versus 500 mg reported
This is 102.05% of the reported amount, calculated by PeptidePrices. Purity and content are separate measurements; no numerical content acceptance range is printed.
Heavy metals
Pb, As, Cd and Hg: Not Detected; PASSED
ICP-MS screening cites USP <232>/<233>. The sheet prints no per-metal concentration or quantitative detection limit, so Not Detected is not converted to zero.
Endotoxin
<5 EU/vial; PASSED — Below 5 EU/Vial Limit
The LAL kinetic chromogenic result is compared only with the laboratory’s printed 5 EU/vial limit. No conversion to EU/mL is supported by the report.
Sterility
Sterile — No Growth; PASSED — Sterility Confirmed
The method is USP <71> direct inoculation, a culture-based method distinct from PCR. No incubation duration is printed.
Fentanyl
Not Detected; PASSED — No Fentanyl Detected
The sheet names LC-MS/MS screening confirmed with immunoassay. It gives no numerical cutoff or detection limit; none is invented.
