About Clean Peptides
A ~9-month-old (domain 2025-10-14) Dutch WooCommerce research-peptide shop (cleanpeptides.nl; cleanpeptides.eu redirects to it) with unusually real identity for a niche EU vendor — stated KVK 99467542, working Dutch phone/WhatsApp, genuine terms and return pages, explicit research-use-only labeling — but it publishes NO COA and names no lab, so its per-product 'Zuiverheid: >=99% (HPLC getest)' claim is entirely unbacked. Does not sell Semaglutide or Tirzepatide.
Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- More transparent than most niche EU research-peptide shops: stated KVK number (99467542), working Dutch phone + WhatsApp (+31 6 82 90 28 52), genuine Algemene Voorwaarden and Retourbeleid pages, and explicit research-use-only labeling, on a live valid-HTTPS WooCommerce site with transparent no-login EUR pricing
- No evidence of fraud and early positive service signals: Trustpilot 4.0/5 (8 reviews) praising fast NL same-day dispatch and responsive WhatsApp support, including a proactive DHL reship after a carrier failure; no fake/reused COAs, no impersonation, and no FDA/DOJ or adulteration finding
Cons
- Publishes NO Certificate of Analysis and names no testing lab anywhere (no COA/lab/certificate page exists on either domain); the per-product 'Zuiverheid: >=99% (HPLC getest)' line carries no batch, date, chromatogram, or verification link, so purity is entirely unverifiable (coa_status none, not verified)
- Young and thin: domain registered 2025-10-14 (~9 months), only 8 Trustpilot reviews, low traffic, ScamAdviser 'very likely unsafe' (algorithmic, driven by domain youth); no physical address and KVK unconfirmed in-register; no published lost/seized/reship guarantee; payment rails unconfirmed; and it does not carry Semaglutide or Tirzepatide
Is Clean Peptides legit? Common questions
Is Clean Peptides a legit peptide vendor?
Clean Peptides scores 44.3/100 (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 Clean Peptides 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 Clean Peptides ship to and how fast?
Clean Peptides reports shipping to Netherlands, typically in around Same-day dispatch if ordered before 12:00 (NL); PostNL/DHL, tracked returns portal; no delivery timeframe published.
What payment methods does Clean Peptides accept?
Clean Peptides accepts bank transfer.
When was this Clean Peptides review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
Live, valid-HTTPS NL storefront that is more transparent than the typical anonymous EU peptide shop (named KVK, real phone/WhatsApp, real terms/return docs) and shows early positive service signals (Trustpilot 4.0/5 from 8 reviews, same-day NL dispatch, a documented goodwill reship), with no evidence of fraud. But there is zero independent verification: no COA is published, no testing lab is named, purity is a bare vendor claim, the domain is young with thin reputation, and payment rails could not be confirmed. The absent independent COA caps it at a borderline D+.
