Peptides in general
A searchable, filterable quick-reference for the research peptides you are likely to come across, approximate molecular weights, CAS numbers and compound classes, gathered in one place. This is background information, not a stock list.
Browse the 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, not a catalogue or a purchase list. Some entries are not sold by Peptide.ST and are listed purely for context. Where a class is noted as non-peptide, the molecule is included for comparison because it is studied alongside peptides. 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 compound is a blend or a mixture, or where no single agreed value exists, the field reads "Approx. N/A". A CAS of "N/A" means no single Chemical Abstracts number is established for that compound.
This list is for orientation across the peptide families, not a catalogue. To see what Peptide.ST currently sells, open the store. To understand how each batch is tested, read how our certificates of analysis work, or look a batch up directly on the COA page.
