The certificate library is per-lot and extensive. CertaPeptides’ own Certificates of Analysis page lists 38 products carrying an independent lab report (59 report entries), plus 1 product line covered only by a supplier batch specification. A second, more detailed vendor page states 63 independent report records and 28 supplier-spec lines — both counts are the vendor’s own, from two different pages, and are not combined into a single figure here. Every independent report names Janoshik as the testing lab and links to Janoshik’s own verifier, verify.janoshik.com. The figures below are as CertaPeptides’ own pages print them. Two representative lots: BPC-157 10mg, Janoshik report 43XQNHEN8C7L, tested 2026-09-18, 99.944% purity, 12.98 mg measured (129.8% of the 10mg label); and Retatrutide 10mg, Janoshik report 3UCGA5FQMWI1, tested 2026-09-17, 99.427% purity, 9.61 mg measured (96.1% of label). All products are sold for laboratory and research use only.

The code was cart-tested directly against the vendor’s storefront. It has a €25 minimum spend and applied at exactly 10% off a qualifying cart, confirmed against CertaPeptides’ own store; a nonsense code was rejected as a negative control. The vendor renamed the affiliate code shortly afterward; the discount rate and mechanism are otherwise unaffected. Prof. Peptide carries no per-milligram price table for this vendor.

Finnrick rates CertaPeptides 80% across 2 tests (read 30 September 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.

Prof. Peptide checked Trustpilot and Finnrick on 30 September 2026. Trustpilot: 4.6 from 94 reviews (read 30 September 2026).

Frequently Asked Questions

Does CertaPeptides have a coupon code?
Yes. Use coupon code PROFPEPTIDE at checkout to save 10% on your order at certapeptides.com. The code has a minimum spend of €25 and was cart-tested directly against the vendor's storefront, where it applied at exactly 10% off.
How do I use the CertaPeptides discount code?
Add at least €25 of items to the cart at certapeptides.com, proceed to checkout, and enter PROFPEPTIDE in the coupon field before paying. Entering it directly at checkout works even without clicking a referral link first — CertaPeptides' affiliate terms honor a manually entered code as a fallback attribution.
Is CertaPeptides third-party tested?
Yes, extensively. CertaPeptides' own Certificates of Analysis page lists 38 products with an independent lab report (59 report entries) and 1 product line covered only by a supplier batch specification. A second, more detailed vendor page states 63 independent report records plus 28 supplier-spec lines — both figures are the vendor's own, from two different pages, and are not combined into one number here. Every independent report names Janoshik as the testing lab and links to Janoshik's own verifier, verify.janoshik.com; that verifier returned a Cloudflare bot challenge to a headless read on this pass, so the figures here are read from CertaPeptides' own pages rather than confirmed directly on the lab's domain. Two representative lots, read in full: BPC-157 10mg, Janoshik report 43XQNHEN8C7L, tested 2026-09-18, 99.944% purity, 12.98 mg measured (129.8% of the 10mg label). Retatrutide 10mg, Janoshik report 3UCGA5FQMWI1, tested 2026-09-17, 99.427% purity, 9.61 mg measured (96.1% of label).
