Guides to reading the evidence
Plain, factual guides for the people who actually evaluate a supplier: how to read a certificate of analysis, how to verify purity independently, what “research use only” means, and how lyophilized peptides are stored and handled in the lab. Every product we sell is independently HPLC-tested by Janoshik and verifiable by key. All of this is educational and for laboratory research use only — no medical, dosing, or use guidance.
Guides
- Reading a COA
How to Read a Certificate of Analysis (COA)
Read an independent HPLC certificate line by line — identity, assayed purity, batch, and the verify key — using our live Janoshik reports as worked examples.
- Verifying purity
How to Verify Research Peptide Purity
What independent third-party HPLC testing actually proves, why it matters, and the red flags that separate a verifiable supplier from an unverifiable one.
- Research use only
What “Research Use Only” Means
A plain explanation of research-use-only materials, what they are not, and the responsibilities that come with purchasing and handling them.
- Storage & handling
Understanding Peptide Storage & Handling (for research)
How lyophilized research peptides are stored and handled in the laboratory — cold chain, desiccation, and light protection — strictly for research use.
- Reconstitution
Reconstitution for Research: A Laboratory Procedure
What reconstitution is, the solvents and sterility involved, and the concentration math — explained as a laboratory procedure. Pairs with the reconstitution concentration calculator.
