Mr Peps publishes sixteen documents and one of them is verified. The Janoshik GLP-3R report names Mr. Peps Labs as the client and matches the laboratory's own record, while the fourteen vendor certificates give a full analytical panel for a named lot and the second Janoshik report prints an unrelated client and remains visible in the library with unresolved vendor attribution.
The rating is 5.5/10 from its factor scores: COA 4.5, reputation 6, transparency 6 and operations 6.5. Only one report has an independent match to the lab record naming the vendor; fourteen Quality Assurance files are vendor-authored and provide no independent laboratory record. Trustpilot shows 3.1/5 from seven reviews.
01Verified record and published certificates
PeptidePrices reviewed Mr Peps' complete public document set of sixteen documents. One is verified: a Janoshik report for GLP-3R, task 169921, that names Mr. Peps Labs as the printed client, records 10.16 mg at 99.492% purity for batch 95823, and was analysed on June 18, 2026. It matches the laboratory's own record, and the library retains it alongside the other fifteen documents. The other fifteen published documents do not carry a verified label. The second Janoshik report, for GLP-2T, task 93208, batch 20251006T40, measures 44.35 mg and 45.14 mg at 99.900% and 99.874% and was analysed on December 12, 2025; it matches the laboratory's record but prints TSC as the client and the manufacturer, so the vendor attribution is unresolved and the report remains visible in the library without a vendor-verified badge or product match. The remaining fourteen documents are Mr. Peps letterhead Quality Assurance certificates, four pages each, one per compound. Each prints a lot number, a manufacturer catalogue number, identity by mass spectrometry, purity by HPLC, single and total impurity, polymer, TFA, acetate, sodium salt, residual solvents, amino-acid composition, net peptide content, water, endotoxin, and microorganism limits. Reported purity runs from 99.08% to 99.63% and net peptide content from 95.0% to 97.8%. Three findings limit what these fourteen documents establish. No document names an independent laboratory, carries a laboratory report number, or resolves to a public lab record. No document prints a fill weight, so a certificate identifies a compound lot and not a listed strength. And the three proprietary blends print a composition that differs from the storefront's own copy: Glow prints a GHK-Cu / Palmitoyl Tripeptide-1 / Epithalon blend, Klow prints a Selank / Semax / Epithalon blend, and Wolverine prints a BPC-157 / TB-500 / AOD-9604 blend. Six compounds publish no document at all: GHK-Cu, Ipamorelin, CJC-1295 With DAC, Cagrilintide, Melanotan 1, and NAD+. We set COA quality at 4.5/10: only one report has a vendor-named independent match to the lab record. The fourteen Quality Assurance files are vendor-authored, name no independent laboratory, print no fill weight, and three blend compositions conflict with the storefront copy.
Independent testing and reputation
Independent customer-review evidence is thin. The only independent review record for the domain is a claimed Trustpilot profile created in November 2025, which shows a TrustScore of 3.1 from 7 reviews. PeptidePrices found no exact-domain Finnrick test profile, and we set reputation at 6/10 while keeping that small, mixed review sample visible.
Catalog, payment, and shipping
The catalogue holds 21 products. Twenty map to a comparison compound and fourteen have an in-stock size, so the price comparison publishes fourteen rows across eleven compounds. The checkout offers three payment methods: Open Banking through Fena Pay with an automatic 5% discount, UK bank transfer, and cryptocurrency in Bitcoin, Ethereum, or Solana. No card option is offered, so no card claim is published. Published terms give free UK shipping over £150 and £3.50 below that, same-day dispatch for orders confirmed before 14:00, tracked delivery in one to three business days, and a 48-hour window to report a damaged, incorrect, or missing item, with refunds in five to seven business days. The delivery policy states United Kingdom addresses only, while the checkout prices other destinations at £9.99.
Company disclosure and rating
The store publishes its legal entity MR. PEPS LABS LTD, company number 17234136, a registered office in Thornton Heath, a telephone number, a support email, and office hours. The company was incorporated on May 21, 2026 and the domain was registered on November 2, 2025. The vendor's sitemap lists three GLP product URLs that its own application cannot resolve and omits nine live products, so the tracked listings use the resolvable product URLs. We set COA 4.5, reputation 6, transparency 6 and operations 6.5 on September 22, 2026, yielding the published 5.5/10 rating. Affiliate status has no score weight.
