Every Genetic Peptides USA customer has a personal code. A friend enters it at checkout and takes 20% off their first order. Each friend's first order adds 10% off your next one, stacking all the way to 50%.
Open to every customer. No sign-up, no dashboard, no minimums.

Enter the email you ordered with below. Your personal code lands in your inbox. If you have an account, the same email works.
02

A friend enters your code at checkout and takes 20% off their first order. It stacks with the automatic stock-up discount.
03
Stack your reward
Every friend's first order adds 10% off your next order, up to 50%. We email you a fresh single-use reward code each time it grows.
Your reward ladder
One friend is 10%. Five is half off.
Only a friend's first paid order counts, and your own orders never do. When you redeem a reward code, the ladder starts again.

Already ordered? Your code is waiting.

One email field, no account needed. Codes go to the address on your order only.
The fine print
Simple rules, no catches
✓Referral codes count on a friend's first order only, and never on your own orders.
✓Points and referral rewards are separate. Points redeem as REWARD codes; referral rewards are the 10% ladder codes. Only one discount code per order.
✓Your friend's code and your reward code each stack with the automatic stock-up discount, but only one code can be used per order.
✓Rewards are discounts on future orders. There are no cash payments.
✓We may pause codes that are posted publicly or used in a way that looks like resale.
