How we make money
Stack-kit is free to read, and it stays that way because of how we're funded. Here's the whole story, plainly.
Last updated
We read the research, build the protocol, and hand you a short shopping list. You buy each item straight from the brand — they handle checkout, shipping, and returns. We don't make, stock, or ship anything, and you don't check out here. When you buy through one of our links, the brand pays us a commission — usually 5–15% of the sale. You pay the same price either way. That's the whole business.
Why you can trust the recommendation
We only earn when you buy something that's actually worth buying — and keep buying it. So our interest is the same as yours: recommend what genuinely works, name what to cut, and never pad a list to make a sale. We point you to the brand we'd buy ourselves, not the one that pays the most. If a brand's testing slips, we change the call and tell the people who bought it.
What we won't do
- Sell placement. Brands can't pay their way into a protocol. They earn a spot on evidence and testing, or not at all.
- Hide the commission. Every protocol says it plainly, right next to the buy button.
- Pad your cart. No "frequently bought together," no upsells. The protocol is the whole list — and it's short on purpose.
- Manufacture urgency. No "only 4 left," no countdown timers, ever.
If something's off
Email us at [email protected]. If a recommendation didn't fit you, that's how the next version gets better — and if a protocol helped, tell a friend. That's the whole marketing plan.
