About Professional Peptides
Young (~6-month, registered 2026-01-09) small US-based research-peptide store that advertises fast discreet domestic US shipping with cold-chain and claims independent third-party testing with COAs on request. Despite the candidate NL/EU label it is a US operation; no third-party lab is named, no per-batch independent COA is published or verifiable, and reputation is thin (Trustpilot 4.6/17, mostly positive) but undercut by one BBB refund-denied complaint and IPQS phishing/suspicious flags on a very-low-traffic new domain.
Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- Live HTTPS storefront using an independent review platform (Trustpilot 4.6/5, 17), with early customers praising responsive knowledgeable support, COAs provided on request, batch transparency, fast domestic shipping and good packaging
- Fast, discreet US domestic shipping with an advertised cold-chain option appropriate for temperature-sensitive research compounds
Cons
- No named third-party lab and no published/verifiable per-batch independent COA (COAs on request only); no Janoshik verification and no Finnrick independent test data, so the 'independently tested' claim and any purity figure are unverifiable
- Very young domain (~6 months, 1-year registration, hidden WHOIS, DV SSL), no disclosed legal entity or address, IPQS phishing/suspicious flags and very low traffic, plus a BBB Scam Tracker complaint of no post-order correspondence and a denied refund

When was this Professional Peptides review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
A real but very new (~6 months) and low-profile US vendor that earns roughly a D+: it claims independent third-party testing and hands out COAs on request, but names no lab, publishes no verifiable per-batch independent COA (no Janoshik/Finnrick record), discloses no legal entity or address, and pairs mostly-positive but thin Trustpilot sentiment with a BBB non-response/refund-denied complaint and IPQS phishing flags. The absence of any verifiable independent testing caps the record.
