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 (retatrutide on 12 Oct 2026; semaglutide and tirzepatide were listed in June) 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
- Tracked shipping from Romania to 27 EU states plus Switzerland and the UK (29 countries, shipping page, 12 Oct 2026); intra-EU parcels avoid the customs-seizure risk that hits US- and UK-to-EU parcels, while UK and Swiss deliveries do cross a customs border. No US delivery
- Retatrutide from EUR 44.49 for 5 mg (EUR 8.90/mg) down to EUR 5.00/mg at 50 mg on 12 Oct 2026, with a published affiliate/referral program; our June walk also priced semaglutide from EUR 19.49 and tirzepatide from EUR 30.99, both no longer listed
- Runs a security page that names its one official domain and lists five lookalike domains (checked 12 Oct 2026)
- In June 2026 only ~20 of ~58 catalogue entries carried an independent Janoshik report. On 12 Oct 2026 its COA page headline read 27 products with independent reports plus 8 product lines on supplier spec only, and linked 41 Janoshik report IDs that we have not re-mapped to products. A supplier "≥98% class spec" is, by the vendor's own admission, not a measurement of the lot you receive
- New operation, with certapeptides.com registered on 7 Feb 2026 (RDAP), CERTALAB S.R.L. on 4 Mar 2026 (J2026014773006) and the WordPress media library also dating 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. Finnrick lists 2 retatrutide tests (both passed, 17 Jul 2026) and Trustpilot shows 4.6 from 114 reviews, but we found no independent Reddit record, and most purity claims rest on reports the vendor chose to publish
- The catalogue narrowed since June; semaglutide, tirzepatide and ipamorelin, all priced in our June walk, no longer appeared on its shop or stock-status pages on 12 Oct 2026, and we do not know why
- Vendor self-submitted for inclusion; this profile is a public-data audit; we have placed no test order
- A lookalike shop at certa-peptides.com, registered 27 Sep 2026, used its branding and listed Bitcoin as payment on 12 Oct 2026

FROM PUBLISHED POLICY AND USER REPORTSPublic reviews
TRUSTPILOT · READ 2026-10-19The company says it invites customers to review. Recurring complaints in the one- and two-star reviews: vial batch codes that do not match the linked Janoshik tests; paid orders not delivered or long delayed. 116 of the 118 reviews were posted in the past 12 months; the company replied to 62% of negative reviews. This is a second-hand signal. Nearly every peptide shop on Trustpilot scores between 4.3 and 5.0, so we weigh the spread, the dates and the complaints rather than the headline score, and never above a lab result. Read the profile.
Audit notes
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. On 12 October 2026 we also read its stock-status, shipping and affiliate pages, Finnrick's vendor page, Trustpilot (through a page summarizer) and Romania's ANAF tax-registry record for the company. We did not place a test order, and we found no independent Reddit discussion of the shop.
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. On 12 October 2026 its COA page showed 27 products with independent Janoshik Analytical reports (about twenty in June), 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.
Who is behind it
CertaPeptides says it is CERTALAB S.R.L. of Bucharest. Romania's ANAF tax-registry lookup on 12 October 2026 returns CERTALAB S.R.L., CUI 54169956, Trade Register number J2026014773006, registered on 4 March 2026 at the Bucharest address printed in the site footer. certapeptides.com was registered on 7 February 2026 (RDAP), which sits against the site's "Founded 2024" line. Two more details we cannot explain: a second ANAF record, CUI 54451735, carries the same company name and address with a 23 March 2026 registration, and the stock-status page says orders ship from a Sibiu warehouse while the registered address is in Bucharest. We have not contacted the company.
What the lab records show
Re-checked 12 October 2026.
| Record | What it shows |
|---|---|
| Janoshik public-listing mirror (337 reports, to 30 June 2026) | 5 CertaPeptides reports, tested 31 March to 20 April 2026 |
| Purity on those 5 | median 99.702%, range 98.005% (epitalon) to 99.788% (selank) |
| Content against label | median 100.2%; GHK-Cu 50 mg at 90.1%, epitalon 50 mg at 90.6%, ipamorelin 10 mg at 100.2%, selank 10 mg at 115.6%, retatrutide 5 mg at 115.8% |
| Identity | confirmed on all 5 |
| Kovera Labs mirror (1,828 certificates, snapshot of 2 August 2026) | 0 name CertaPeptides |
| Vendor COA page | 41 distinct Janoshik report IDs linked; the page headline reads 27 products with independent reports plus 8 supplier-spec product lines; the homepage says "53 published lab reports" |
| Finnrick vendor page (12 Oct 2026) | 80%, #101 of 457 vendors, on 2 retatrutide tests, both passed, both dated 17 July 2026; individual values sit behind Finnrick's membership login |
None of the five sits below 90% of label. Two sit above 110%. Overfill is common in published reports: across all 224 reports in our Janoshik mirror with both a label and a measured amount (non-peptides and reissued copies included), the median is 108.5% of label. Our purity and fill study, which keeps only peptide results and counts each test once, puts Janoshik at 109.3% across 182. All of these are reports the vendor chose to make public, so they show what it was willing to disclose, not a random sample of what ships. You can open each one on Janoshik's portal, or run the report ID through our COA verifier.
Finnrick's two tests are too few to rate the vendor on, and we cannot read the values behind its login, so we count them as corroboration, not a result.
What is still open
- COA coverage vs catalogue. On 12 October 2026 its COA page showed 27 products with an independent Janoshik report; products without one ship on a supplier spec only. No public record shows whether the class spec holds for an untested lot. A buyer can check whether the product being bought is one of the 27 with a Janoshik report.
- The "founded 2024" timeline. The site claims a 2024 founding and 2024 lab partnerships, but the Romanian company registration (4 March 2026), the domain (7 February 2026) and the site's media library all date to 2026, and a second ANAF record carries the same company name. Until that is reconciled we do not take the track record at face value.
- Shipping reliability. Intra-EU dispatch with tracking is the claim; we hold no measured transit times or seizure rates.
- Identity, not just purity. Janoshik HPLC gives purity. Check that the report for a GLP compound also shows a mass-spec identity result, 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. On 12 October 2026 retatrutide was EUR 44.49 for 5 mg (EUR 8.90/mg), EUR 69.99 for 10 mg, EUR 94.49 for 15 mg, EUR 118.99 for 20 mg, EUR 164.99 for 30 mg and EUR 249.99 for 50 mg (EUR 5.00/mg), with 5% off for 3 or more of a product, 10% for 5 or more and 15% for 10 or more. BPC-157 was EUR 19.99 for 2 mg and EUR 29.99 for 5 mg, and GHK-Cu started at EUR 39.99.
Our June 2026 catalog walk recorded semaglutide from EUR 19.49, tirzepatide from EUR 30.99, BPC-157 2mg from EUR 27.99, GHK-Cu 50mg from EUR 62.99 and ipamorelin 5mg from EUR 23.99, so several prices have fallen since. Semaglutide, tirzepatide and ipamorelin no longer appeared on the shop or stock-status pages on 12 October 2026 (36 products listed), and we do not know why. We have not re-run our per-mg index for this update; we track per-mg cost across the audited vendors at /peptides-index.
FAQ
Is CertaPeptides legit? On public records, yes, with caveats. CertaPeptides is CERTALAB S.R.L., a Romanian company, and its Janoshik reports sit on Janoshik's own verify portal. The five CertaPeptides reports in our Janoshik mirror (31 March to 20 April 2026) all confirm identity, with purity from 98.005% to 99.788% (median 99.702%) and content from 90.1% to 115.8% of label. Vendors choose which reports to publish. The caveats are its newness, the "founded 2024" timeline mismatch, and that part of the catalogue ships on a supplier spec rather than a per-lot test. The company is CERTALAB S.R.L. (CUI 54169956, registered 4 March 2026 per Romania's ANAF record). This is a public-data preview, not a first-hand audit; we score it 78/100.
Is certa-peptides.com the real CertaPeptides site? Not according to CertaPeptides. Its own security page names certapeptides.com as its only official domain. certa-peptides.com, with a hyphen, was registered on 27 September 2026 through eNom. On 12 October 2026 it ran a shop in CertaPeptides' branding that listed Bitcoin as a payment method, which the official site does not, and showed both its own support address and CertaPeptides' real one. We do not know who operates it.
What do CertaPeptides reviews say? On 12 October 2026 Trustpilot showed 4.6 from 114 reviews, with one visible 1-star review, dated 5 October, saying test results are not linked correctly to batches. We read Trustpilot through a page summarizer and have not opened it in a browser. Finnrick lists 2 retatrutide tests for CertaPeptides, both passed and dated 17 July 2026, which is too small a sample to rate it on. We found no independent Reddit discussion. Our assessment rests on its lab reports, company records and published terms.
Does CertaPeptides publish COAs? Yes. On 12 October 2026 its COA page linked 41 distinct Janoshik Analytical report IDs on Janoshik's own verify portal (about twenty in June), 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, tracked, dispatched within 1 to 2 business days: its shipping page on 12 October 2026 lists 27 EU member states plus Switzerland and the UK (29 countries) and no US zone. Our June 2026 walk recorded 33 countries, including Norway, Iceland, Israel and Serbia. Rates run from EUR 4.99 in Romania and EUR 17.99 across core EU countries (3 to 7 days) to EUR 45.99 by DHL Express to the UK, with free shipping over EUR 200. Payment is SEPA bank transfer or Paysera, with no card or crypto. A shop that asks for Bitcoin under the CertaPeptides name is not the official one.
Does CertaPeptides ship to the US? No. Its shipping page on 12 October 2026 lists 27 EU member states plus Switzerland and the UK, and no US zone. UK and Swiss parcels cross a customs border; intra-EU parcels do not.
