PS Peptides Review: Pricing, COAs, Testing, and What We Found
An independent evidence review of PS Peptides (pspeptides.com): public vial prices and a certificate library with laboratory matches at North American Diagnostics.
PS Peptides is now a curated vendor on PeptideBenchmark because the storefront publishes vial prices and a certificate library a reader can check at the issuing laboratory.
Reviewed September 24, 2026. Relationship update September 25, 2026: code BENCHMARK is 10% off, and outbound product links add ?ref=benchmark. That relationship does not change the findings or the score. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
The short version
The public catalog includes single-vial peptides plus sprays, tablets, a skin serum, and accessory products. Seventy-two vial strengths had a comparable regular price. Ready sprays and tablet bottles with a labeled dose and count are compared on the spray and capsule lanes, not against reconstitution vials. The GHK-Cu skin serum and the Cut & Glow multi-vial bundle stay off those lanes.
528 of 533 published PDFs match a laboratory page under the client ProSupply Peptides | pspeptides.com. A certificate covers the tested sample. It does not test every other strength or the vial a reader receives.
Pricing
Ranked prices are the regular single-vial list price. The vendor advertises free shipping on any order and free UPS 2nd Day Air over $200. Those shipping terms are vendor-stated observations from September 24, 2026. The vendor also publishes its own affiliate program. That program is not a PeptideBenchmark offer and is not applied to the ranked price.
Testing
The certifications page hosts current and older laboratory PDFs. The confirmed laboratory matches name the client ProSupply Peptides | pspeptides.com. The library includes separate analytical, heavy-metals, endotoxin, sterility, and fentanyl-screen reports. A result in one document does not establish the results of another; check the report for the relevant product and lot.
Five of the 533 PDFs did not have a confirmed laboratory match in this review. Accessory products and multi-product bundles are not treated as peptide vials.
What we did not verify
No physical vial was tested by PeptideBenchmark. New Jersey is the location the About page states. It is not a street-level facility inspection.

Common questions
Does PS Peptides publish COAs?
Yes. The September 24, 2026 review found 533 certificate PDFs on the public certifications page. 528 resolve at North American Diagnostics under the client ProSupply Peptides | pspeptides.com.
Does PeptideBenchmark have an affiliate relationship with PS Peptides?
Not on the September 24, 2026 review date. On September 25, 2026 PeptideBenchmark added a relationship: code BENCHMARK is 10% off, and product links add ?ref=benchmark. That does not change the evidence findings or the score. The dashboard 18% figure is partner commission, not a second shopper discount.
Where does PS Peptides ship from?
The About page says the company has a 25-person team based in New Jersey and that compounds are manufactured in the United States. The contact page does not publish a street address. Orders placed before noon Eastern typically ship the same business day.
