Less noise.
More price clarity.
PepSpotter compares the prices research-peptide vendors publish, so you can see what a vial really costs before you visit a store.
What we do
Every day we read the public product listings of the vendors we track, match each listing to its compound, amount per vial and pack size, and work out a comparable price. You see the vendors side by side, cheapest first, each with a link to the vendor’s own page.
What we don’t do
PepSpotter sells nothing, takes no commission and accepts no payment for placement. We do not test products, vouch for vendors or give medical advice. Everything listed is offered by its vendor for research use.
USA and Canada
We compare vendors that sell in US and Canadian dollars. Pick a destination and a display currency at the top of any page; Canadian-dollar prices are converted at the European Central Bank’s reference rate of the date shown.
Honest numbers
A listing that does not say how much it contains is shown apart and never ranked. A price that has not been re-checked for 48 hours is marked as stale. Shipping, tax and duties are not included, and the vendor’s checkout total is final.
