Cheapest Cortagen 20 mg
10 vendors that pass our metascore cutoff (70+) list Cortagen in 20 mg vials with a current, in-stock price. The lowest price per milligram is USD 0.375 at LN Peptides (10 × 20 mg = 200 mg for USD 75.00); the lowest total at checkout is USD 27.50 at Peptidology (1 × 20 mg). Cheapest is not the same as best: the metascore beside each vendor sums up independent lab tests of vials bought like a customer would, whether its own lab reports hold up and whether its claims match what buyers measured. Affiliate links never change the order.

Which listings are left out?
Vendors below a metascore of 70, vendors you can only order from by message, listings marked out of stock, prices older than 14 days, and prices far outside the range other vendors charge for the same peptide (usually a vial-count mistake or a whole kit priced as one vial).
How current are these prices?
Prices are read from each vendor's own website; the newest on this page was checked on 13 Nov 2026. The page is rebuilt with every price refresh, and a listing drops off once its price is more than 14 days old. Check the vendor's page before ordering.
Do affiliate links change the ranking?
No. The tables are sorted by price only. Some Buy links are affiliate links that may earn PeptideCompare a commission at no extra cost to you.
