Prices are the vendor's list price for one vial on the check date, in USD, before shipping. Ranked by price per mg; vendors that only sell multi-vial kits are listed after single-vial prices, at the per-vial price; sponsorship never changes the order. Links marked "Check price" may earn us a commission.

FAQ
LL-37 price questions
Where is LL-37 cheapest?

How much does LL-37 cost per mg?

How often are these prices checked?
Weekly. We read each price from the vendor's own product page and save every check, so each row shows the change since last week.
What does the COA badge mean?
The vendor publishes certificates of analysis (lab reports) for its products on its own site. 83% of the in-stock offers above come from vendors that do. Check that a report exists for the exact product and lot you order: a COA shows what a lab measured for one batch, not a guarantee about the vial you receive.
