What testing does and does not do. Laboratory testing on this page is analytical quality control for research materials. A test measures what is in the sample that was sent: its identity, purity, quantity, or a specific contaminant. A certificate of analysis covers only that sample, on that date. It does not establish that a material is safe or effective, it does not approve any product for human or veterinary use, and no product or material referenced here has been evaluated by the Food and Drug Administration. All materials are for in-vitro laboratory research purposes only. Not for human consumption.
Disclosure: Peptide Stores Online lists these laboratories for information and comparison. Most listings are plain links and earn nothing. Where a laboratory link is an affiliate link, it is marked as a partner link next to the link itself, and Peptide Stores Online may earn a commission on orders placed through it, at no extra cost to you. Affiliate status never affects whether a lab is listed or how listings are ordered.

| Test | Method | Price |
|---|---|---|
| Identity, amount and purity (base)Base testing is HPLC. Mass spectrometry screening is a paid add-on. | HPLC | $215 |
| LC-MS contamination screenAdd-on, plus $205. | LC-MS | $205 |
| EndotoxinAdd-on, plus $180. A separate vial is preferred. | LAL | $180 |
| SterilityAdd-on, plus $290. This is a microbial count, not a USP <71> culture. | TAMC and TYMC microbial counts | $290 |
| Heavy metalsAdd-on, plus $105. | ICP-MS | $105 |
| Net contentAdd-on, plus $145. The closest retail add-on to a formal net content measurement. | CHNS elemental analysis | $145 |
| Blind testingGLP-1 blind test $360. Per compound blind tests are sold as named products in the e-shop. | HPLC (base test run blind) | $360 |
Order per compound in the e-shop and ship vial(s) internationally at your own cost. A separate vial is preferred for endotoxin.
Restrictions: International shipping to the Czech Republic at the sender's cost.
Delivery: Report verifiable by task number plus key, or QR code. The public database is opt-in and publication may be a paid add-on per secondary sources.
Public verification: Task number plus verification key, or QR code, on the lab's verification system.
Step by step instructions for checking a certificate at the issuing lab are on the verify a COA page.
Not ISO/IEC 17025 accredited, by the lab's own framing.
The lab describes its COA as a community grade check, not a regulatory document. Method detail on COAs is sparse and raw data is a paid extra.
The community default for disputes and vendor guarantee claims, with a decade plus track record. Caveats: no ISO/IEC 17025 accreditation, sparse method detail, raw data is a paid extra, public database is opt-in, and a February 2026 customer data breach was reported by PeptideCritic (secondary, not confirmed by the lab in the pages read).
