How buy 1 get 1 free works
Step 1
Add any vials
Choose any research peptide vials across the catalog. They do not have to be the same product or the same strength.
Step 2
Every 2nd vial is free
For every two eligible vials in your cart, the lower-priced one is free. Add 2 vials, pay for 1; add 4, pay for 2.
Step 3
No code to enter
The free vials are marked in your cart automatically. There is nothing to type in and no other offer to compare.
Applies to eligible peptide vials only — not shipping, wholesale orders, gift cards, subscriptions or non-vial supplies. Vials can be different products; in each pair the lower-priced vial is the free one.
