Why we did it this way
We used to sell fixed stacks — a pre-set box at a pre-set price. The trouble with a fixed kit is that it decides for you, and if one thing inside it goes out of stock the whole box either stops working or ships short.
So the discount now sits on the cart instead of on a product. You pick whatever three things you actually want. Every item is a real product with its own stock, so nothing can arrive missing, and the maths does not change when we add something new to the range.
It applies to everything in supplements. Apparel and gift cards are not included, and it does not stack on top of a discount code or the Subscribe & Save rate — you get whichever is the better deal.
Four that make sense together
Nothing here is a fixed bundle. These are just combinations we would actually recommend, priced at list so you can see what the 15% takes off.

The honest note
Three supplements is not automatically better than one. If creatine is all you need, buy creatine and ignore this page — a discount is a bad reason to own a tub you will not finish.
What the ladder is genuinely useful for is the case where you were going to buy two things over two months anyway. Buying them together costs less and means you actually start both. If you are not sure what belongs together, the 60-second quiz will narrow it down.

Frequently asked questions
How does the stack discount work?
Add any two supplements to your cart and 10% comes off automatically. Add three or more and it becomes 15%. There is no code to enter and no fixed bundle to choose.
Do the items have to be a matching set?
No. Any combination of supplements counts. The discount is applied to the cart, not to a particular product, so you can mix protein, creatine, pre-workout and daily capsules however you like.
Does it work on apparel or gift cards?
No. The ladder applies to the supplements range only.
Can I use a discount code as well?
No, they do not combine. You get whichever is the better value, so you are never worse off.
Does it apply to Subscribe and Save orders?
Subscribe and Save has its own 10% rate and free shipping, and the two do not stack. Whichever is the better deal is the one applied.
What happened to the old stacks?
We retired them. A fixed kit decides for you and breaks when one component goes out of stock. The ladder does the same job, on any combination, without that problem.
