About PeptiLAB
PeptiLAB.cz is not a peptide vendor but a young (domain 2026-03-11) Czech-language review and affiliate content site run by an individual (MUDr. David Martinu) that funnels visitors to external EU sellers (Kensington Labs, My-Peptides, Ascension Peptides) via affiliate links and code PEPTILAB10. It sells nothing itself: no cart, no prices, no shipping, no payment, and no COA of its own.
Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- Openly transparent affiliate model (clear commission disclosure, 'price unchanged for you'), with GDPR and terms pages, clean HTTPS, and a research-use-only 'not for human consumption' disclaimer
- Educational content that steers readers toward EU suppliers with COAs rather than the cheapest option, and no evidence of fraud – no fake/reused COAs (it publishes none), no fake-review scheme, no brand impersonation or FDA/DOJ finding
Cons
- Not a vendor at all – an affiliate funnel with no cart, no prices, no shipping and no payment on-site; it publishes no COA of its own, names no testing lab, and shows no purity numbers, so all product trust transfers to the external sellers it promotes
- Very young (~4-month domain, created 2026-03-11) and anonymous-beyond-norm: individual name plus info@peptilab.cz only, no ICO/legal entity/address/phone, and zero independent reputation of its own (the 'Peptilab' scam/Trustpilot hits are unrelated .co.uk/.com.au sites)
Is PeptiLAB legit? Common questions
Is PeptiLAB a legit peptide vendor?
PeptiLAB scores 26.2/100 (F). Because we could not verify an independent third-party COA, its grade is capped under our integrity gate, treat purity and quality claims with caution until independent testing is provided.
Does PeptiLAB provide third-party lab testing?
No independent third-party COA was on file at our last review. Without external lab verification we cannot confirm what is in the vial, and the grade is capped.
Where does PeptiLAB ship to and how fast?
PeptiLAB reports shipping, typically in around N/A – affiliate/review site, no fulfilment (purchases ship from third-party vendors).
When was this PeptiLAB review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
A transparent-but-brand-new Czech affiliate/guide site rather than a seller: it publishes no COA, names no lab, shows no prices, and handles no shipping or payment, delegating all trust to the third-party EU vendors it promotes for commission. HTTPS, terms/GDPR and a research-use-only disclaimer are in place and there is no sign of fraud, but with no independent COA and no reputation of its own the record caps at a borderline D. Note: the 'Peptilab' Trustpilot/scam reports online are unrelated .co.uk/.com.au namesakes, not this site.
