How the offer works

Ends November 3 at 23:59 CET

How is my best offer chosen?+

We compare 20% off your peptide selection with Buy 2, Get 1 Free and apply whichever saves you more. One or two items qualify for 20% off. The offers never stack.

Can I mix different products?+

Yes. Mix products and strengths, or choose three of the same item.

Which item is free?+

When Buy 2, Get 1 Free is the better offer: For every three items, the lowest-priced item is free. The order in which you add your items does not decide which one is free.

What happens at six items?+

When Buy 2, Get 1 Free is the better offer: The two lowest-priced items in your basket are free. Nine items make the three lowest-priced items free.

How are bundles counted?+

One bundle counts as one item, regardless of the number of products inside it.

Can I combine discount codes?+

One discount applies at a time. If the Halloween offer saves more than your current code, the cart offers you a choice to switch.
