PeptideScouter is an independent price index for research peptides. We collect prices from public vendor catalogs, normalize them to cost per milligram, and let you sort, compare, and find the best prices. Some outbound links are affiliate — you often get a discount at checkout, and the commission keeps this index free to run.
One page, every tracked vendor's price for a given peptide. Click any column header to sort.
All listings are converted to USD and divided by milligrams of active peptide so sizes and vendors are directly comparable.
Every row records its vendor URL and a last-seen timestamp. Click through to the vendor at any time.
No rankings, scores, or editor's picks.
If you see an out-of-date price, know of a vendor we should index, or want to flag something wrong, email us.
