Contains affiliate links. We may earn a commission on purchases. More
PSPeptides is a US research peptide vendor that says it manufactures in a cGMP-compliant facility in Temecula, California. Its certificates of analysis carry a batch number and the lab's name, N.A. Diagnostics, and each test ID can be looked up on the lab's own website. It ships same or next business day and has a 4.6 Trustpilot rating from 268 reviews, but it shows no company name or address and its catalogue is visible only to registered researchers.
Disclosure: this review contains affiliate links; we may earn a commission. It uses the same checks as every other vendor, and the watch-outs below are shown in full. How we work.
What we found good
- COAs carry a batch ID and name the lab: for example BPC-157 5 mg, batch PSP-06112026BP, 99.92% HPLC purity (ordered 11 June 2026).
- Each test ID returns the same report on the lab's verify portal (nadiagnostics.com/verify).
- Reports cover more than purity: heavy metals, endotoxin, sterility and fentanyl screening are listed.
- Orders placed before 2 PM EST ship the same day; others ship the next business day.
- Free UPS 2nd Day Air over $200 and free UPS Next Day Air over $400.
- If a third-party test shows the wrong product or HPLC purity below 80%, it refunds the order plus the cost of the test (claim within 30 days).
- Takes cards, Afterpay, Klarna, Apple Pay, Google Pay, Shop Pay, CashApp and Zelle.
- 4.6 on Trustpilot from 268 reviews, the highest rating among the vendors we recorded.
Watch-outs
- The catalogue and prices are only shown to registered researchers, so you cannot compare prices before signing up.
- The testing lab is young and its independence is not established: nadiagnostics.com was registered in June 2026 and states no accreditation.
- No company name or street address is shown on the site. The About page places the team in New Jersey and manufacturing in Temecula, California.
- The About page offers support by call or text; the Contact page says there is no phone support.
- Shipping banners disagree: one says free shipping on any order, others set thresholds at $200 and $400.
- No returns. Defective, broken or missing items must be reported within 3 days of delivery with photo and video.

What we could not verify
- Whether N.A. Diagnostics is accredited or fully independent of the vendors it tests.
- No independent test results from Finnrick or similar community testing were published at our check.
- The homepage says current batch results are posted on each product page before the batch ships. Product pages sit behind the login, so we could not check this.
- Lost-in-transit parcels are not covered by the published policy we read.
Facts were checked on 2026-11-04 from the vendor's own pages. Vendors change prices and policies, so check the current page before ordering. See how we review.
