Score breakdown
Strengths & weaknesses
- Publishes genuine third-party Janoshik Analytical COAs (HPLC + mass spec, several with heavy-metals panels) linked directly to Janoshik's public verify portal — buyers can confirm report IDs the vendor cannot edit
- Honest two-tier labeling — "Janoshik Verified" vs "Supplier Batch Specification" — and explicitly states the supplier spec describes a class standard, not a measurement of the specific lot. Unusually transparent framing for the niche
- Uses real compound names and CAS numbers (Semaglutide, Tirzepatide, Retatrutide) rather than proprietary relabels, so cross-vendor per-mg comparison is straightforward
- Named EU legal entity (CERTALAB S.R.L., Bucharest, Romania) and a named founder, with a registered company number and phone — more corporate transparency than most grey-market vendors
- Intra-EU shipping from Romania to 33 countries with tracking, which sidesteps the customs-seizure risk that hits US/UK-to-EU parcels
- Competitive EUR pricing, especially on the GLP-1 cluster (semaglutide from EUR 19.49, tirzepatide from EUR 30.99), with a published affiliate/referral program
- Runs a security page warning buyers about a typosquat domain — a sign of an operator paying attention to brand-impersonation risk
- Only ~20 of ~58 catalogue entries carry an independent Janoshik report; the remaining ~38 ship on a supplier "≥98% class spec" that, by the vendor's own admission, is not a measurement of the lot you receive
- New operation — the Romanian entity registration (J2026...) and the WordPress media library both date to 2026, which sits awkwardly against the site's "Founded 2024" / "2024 lab partnerships" timeline
- Payment is SEPA and Paysera only (no card or crypto) — fine for EU bank-transfer buyers, a hard stop for everyone else
- No first-hand order placed by us, and no independent community track record retrieved yet — purity claims rest on the vendor's own published reports until we test a vial ourselves
- Vendor self-submitted for inclusion; this profile is preview-data only, first-hand audit pending

FROM THE BENCHWhat we read
For this preview we walked the public catalog (about 58 listed entries across peptides, blends, kits and consumables), the COA Vault, the about-page and its company disclosures, and a representative set of the linked Janoshik reports on Janoshik's own verify portal. We confirmed payment, shipping and returns terms from the site. We did not place a test order, and we did not retrieve any independent community history this round.
Why CertaPeptides matters in 2026
Most vendors that email us asking to be audited lead with marketing. This one led with a link to its COA page — and the COAs are real. CertaPeptides publishes roughly twenty independent Janoshik Analytical reports, each linked to Janoshik's public portal with a report ID and code we can verify without the vendor's involvement. That is the strongest evidence class in this market, and it is the bar our methodology is built around.
Two things stand out beyond the COAs. First, the vendor draws an explicit line between lots it has had independently tested and lots it ships on a supplier "≥98% class spec," and it states plainly that the class spec is not a measurement of the specific lot. That kind of honest hedging is rare. Second, the headline compounds are sold under their real names with CAS numbers, not proprietary house labels — so a buyer can actually compare a CertaPeptides retatrutide against anyone else's.
What we'd verify in a full audit
- COA coverage vs catalogue. About a third of SKUs have an independent Janoshik report; the rest are supplier-spec only. A first-hand audit would send a supplier-spec compound to an independent lab to see whether the class spec holds for an untested lot.
- The "founded 2024" timeline. The site claims a 2024 founding and 2024 lab partnerships, but the Romanian company registration and the site's media library both date to 2026. We would reconcile that before treating the track record at face value.
- Shipping reliability. Intra-EU dispatch with tracking is the claim; we would check transit times and seizure rates against it across multiple orders.
- Identity, not just purity. Janoshik HPLC gives purity; we would confirm mass-spec identity on a GLP compound ourselves, since identity is where the market's worst failures hide.
How CertaPeptides compares on price
Prices are in EUR and aimed at EU buyers who avoid a customs border by ordering intra-EU. From the public catalog walk (June 2026): semaglutide from EUR 19.49, tirzepatide from EUR 30.99, retatrutide from EUR 94.49, BPC-157 2mg from EUR 27.99, GHK-Cu 50mg from EUR 62.99, ipamorelin 5mg from EUR 23.99. The GLP-1 cluster in particular undercuts a lot of the US-priced field once you account for the lack of customs exposure. We track per-mg cost across the audited vendors at /peptides-index.
FAQ
Is CertaPeptides legit? Public signals are stronger than most new vendors we see — verifiable third-party Janoshik COAs, a named EU legal entity, real compound names, and honest labeling of what is and isn't independently tested. The caveats are its newness, the "founded 2024" timeline mismatch, and that most of the catalogue ships on a supplier spec rather than a per-lot test. This is a public-data preview, not a first-hand audit.
Does CertaPeptides publish COAs? Yes — about twenty independent Janoshik Analytical reports hosted on Janoshik's own verify portal, plus supplier batch specifications for the rest of the catalogue. Run any report ID through our COA verifier or Janoshik's portal directly.
Where does it ship and how do you pay? From Romania to 33 countries (the EU plus the UK, Switzerland, Norway, Iceland, Israel and Serbia), tracked. Payment is SEPA bank transfer or Paysera — no card or crypto.
