Test results in numbers
Jolt Peptides publishes 3 certificates of analysis from independent laboratories. For every report, the table shows the exact sample tested as written on the certificate, the laboratory, the HPLC purity, the measured amount and the analysis date. You can verify Janoshik reports at janoshik.com/verify with the key provided, and Finnrick reports at finnrick.com.

Individual results
- GHK-Cu 50 mg (MJUQRJ5) – Finnrick (analysis by Krause Analytical), analysed 30 Dec 2025, HPLC purity > 99.95%, measured 50.9 mg (101.7% of declared).
- Semax 10 mg (#224311) – Janoshik Analytical, analysed 25 Aug 2026, HPLC purity 99.634%, measured 11.55 mg.
- Bacteriostatic water 3 ml (#224323) – Janoshik Analytical, analysed 24 Aug 2026, benzyl alcohol measured at 8.19 mg/ml.
Every certificate applies to the specific sample tested. For some products a sample of a different size or one component of a blend was tested, which the table always states. We will send you the report for a specific batch on request.
Our independent testing laboratories
We do not do our own testing. We send selected batches to external laboratories, so the results you read are not produced by the seller.
-
Janoshik Analytical ↗
A widely used independent laboratory for HPLC purity and identity testing of research peptides.
-
Finnrick.com
Finnrick ↗
An independent testing platform where samples can be sent and results verified publicly.
-
LiquiLabs.cz ↗
Our regional Czech laboratory partner for independent analytical verification of peptide purity.
How to read a peptide COA
A certificate of analysis (COA) is a laboratory report for one tested batch, and it is what the peptide test results on this page are based on. For research peptides it usually confirms three things: identity (the substance matches the label, usually verified by mass spectrometry), purity (the share of the target peptide measured by HPLC) and the measured amount in the vial compared with the declared amount.
Always check the product name, the declared weight (for example 5 mg or 10 mg), the test date and the laboratory. A safety data sheet (SDS) is a different document: it describes hazards, handling, storage and disposal, not purity.
What laboratory peptide tests measure
Purity by HPLC. High-performance liquid chromatography separates the target peptide from synthesis by-products. The result is given as a percentage of the total signal; research-grade material is usually expected to be above 98%.
Identity by mass spectrometry. The measured molecular weight is compared with the theoretical weight of the sequence, for example about 813.9 g/mol for Semax. A match confirms that the vial contains the declared substance and not a similar peptide.
Vial content. Some reports also state the actual number of milligrams in the vial. This matters for reconstitution: an underfilled 5 mg vial changes every concentration you calculate.
Why independent testing matters
A report from the seller is a claim; a report from an external laboratory is evidence. That is why the test results on this page come from the laboratories Janoshik Analytical, Finnrick and LiquiLabs, and we link to every report in full, not just a summary.

Questions about testing
What is a certificate of analysis (COA)?
A COA is an independent third-party report for a specific batch. For us, these are reports from Janoshik Analytical, LiquiLabs.cz or Finnrick for batches we have had independently tested. It documents identity, HPLC purity and the test date.
What tests do the peptides undergo?
We work with verified suppliers and independent laboratories; we do not do our own testing. Selected batches are tested by Janoshik Analytical, LiquiLabs.cz and Finnrick for HPLC purity and identity. The average HPLC purity in our published Janoshik reports is 99.7%.
Why does a product only have a safety data sheet?
Not every batch has a published third-party report yet. Every product still matches the supplier’s tested batch specification. Send us the batch code and we will send you the available report.
What is the difference between a COA and an SDS?
A COA states what was measured in a specific batch: identity, purity and amount. A safety data sheet (SDS) describes the substance’s hazards, safe handling, storage and disposal.
Can I verify the test results myself?
Yes. We link to every report on this page in full, so you can check the product name, declared weight, test date and laboratory. Finnrick publishes results on its finnrick.com platform. For a different batch, send us its code.
