I write about how research compounds are tested, verified, and handled in the lab.
New writing, occasionally
Testing standards and lab notes. Nothing else, and no fixed schedule.

- Reconstitution for Research: A Laboratory ProcedureWhat reconstitution is, the solvents and sterility involved, and the concentration math — explained as a laboratory procedure. Pairs with the reconstitution concentration calculator.
- 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.
- How to Verify Research Peptide PurityWhat independent third-party HPLC testing actually proves, why it matters, and the red flags that separate a verifiable supplier from an unverifiable one.
- 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.
- What “Research Use Only” MeansA plain explanation of research-use-only materials, what they are not, and the responsibilities that come with purchasing and handling them.
