How to Read a Certificate of Analysis
Every batch has its own certificate of analysis — a COA — issued by an independent lab.
It records what was tested and what the lab found.
The same data prints on your vial label and resolves through batch verification.
- Lot / Batch
- The unique identifier for one production run. Match it to the number on your vial.
- HPLC purity
- The measured percentage of the target compound in the sample (see below).
- Method
- The analytical technique used — typically HPLC-UV/VIS for purity and assay.
- Test date / Lab
- When it was tested and which accredited laboratory performed it.

What “HPLC Purity” Means
HPLC separates a sample into its components so each one can be measured.
The purity figure = how much of the chromatogram is the compound you actually ordered.
We publish the real number per lot — not a blanket “99%+” badge. Higher number, fewer related impurities in that batch.
Lab handling
Reconstitution & Concentration
Lyophilized — freeze-dried — compounds are dissolved in bacteriostatic water for lab work.
Concentration (mg/mL) is simple math: peptide mass ÷ water volume added.
The calculator below does it for you. It's on every product page too.
This is lab-handling reference only — not dosing guidance, administration instructions, or medical advice. Products are for research use only.
Stability
Storage & Handling
- Lyophilized
- Stored at −20°C, freeze-dried compounds are stable long-term; keep sealed and dry.
- Reconstituted
- Once in solution, refrigerate and use within the working window; avoid repeated freeze-thaw.
- Shipping
- Lyophilized material is stable for standard shipping; refrigerate or store at −20°C once it arrives.
Catalog
Compound Classes
The library is organized by mechanism — the way the literature sorts them, not by marketing category. Each class links to the filtered catalog.
