Compound library
A searchable, filterable quick-reference for the research peptides in and around the Peptide.ST catalogue, approximate molecular weights, CAS numbers and compound classes, all in one place.
Browse the catalogue & reference
Use the search box to filter by compound name, class or CAS number, or tap a class chip to narrow the list. Every molecular weight shown here is approximate and provided for reference only, confirm the exact figure for your batch against its certificate of analysis.
Reference only
This table is a study aid. Compounds are supplied strictly for in-vitro laboratory and research use; nothing here is medical, dosing or usage advice for humans or animals.

About these figures
Molecular weights are listed to one decimal place and are approximate, small differences arise from salt form, counter-ions and rounding convention, so always defer to the figure printed on your batch's certificate of analysis. Where a single product is a blend, both component weights are shown.
Items marked In stock are available now on the Peptide.ST catalogue, and Coming soon items are in the pipeline. Rows marked Reference are not currently sold; they are listed here purely for context and comparison across the peptide families. To verify the purity and identity of any batch, look it up on the COA page.
