How Stack-kit makes money
Affiliate commissions. We earn a percentage of supplement purchases readers make through our links. You pay the same price you'd pay direct from the brand. We don't sell supplements ourselves. The protocols stay free.
The mechanism
When you click a "Buy via our affiliate link" button on a Stack-kit protocol, the destination URL carries a tracking parameter that attributes the eventual purchase to Stack-kit. The brand then pays Stack-kit a commission — typically 5-15% of the purchase value depending on the brand's affiliate program.
What this means in practice
Stack-kit's incentive is to recommend products you actually want to buy and keep buying. If we recommend a low-quality brand, you don't buy. If you don't trust the recommendation, you don't click. The economic alignment runs through your judgment of our protocol quality, not through any one-time sale.
Stack-kit's anti-incentive is to inflate cart sizes. A protocol that sells you 14 supplements you don't need does not earn repeat purchases. Our protocols are short on purpose — typically 4-7 items per protocol, with explicit "what to cut" sections that often remove more than they add. Smaller protocols sustain longer.
Stack-kit's brand-agnostic posture is the moat. We recommend the brand we'd buy, not the brand that pays us most. When third-party testing patterns change at a recommended brand, we update the recommendation and email past buyers. We can't do that if we'd sold our shelf space.
Affiliate networks we use
We work through industry-standard affiliate networks (ShareASale, Impact) and direct brand affiliate programs (Momentous, Thorne, Pure Encapsulations, etc.). The networks track clicks, attribute purchases, and pay commissions on a regular cycle. Stack-kit's affiliate IDs are configured at the platform level; tracking parameters are appended to outbound links automatically.
What we won't do
- Sell placement. Brands don't pay Stack-kit to be included in a protocol. They earn slots by evidence quality + third-party testing.
- Hide affiliation. Every protocol page carries an inline affiliate disclosure above the cart CTA. Every learn page links here.
- Cross-sell out of category. Stack-kit protocols don't carry "frequently bought together" widgets pushing unrelated products. The protocol IS the bundle.
- Manipulate scarcity or urgency. No "only X left," no "act now," no countdown timers, no manufactured cohorts.
- Anchor on a celebrity founder or biohacker persona. Stack-kit's authority is editorial + research-rigor.
What we'd want you to do
If the protocol is useful, buy through our links. Recommend Stack-kit to a friend if the protocol earned that. Email us if a recommendation didn't fit your situation — that feedback shapes the next protocol amendment. Subscribe to the newsletter if you want updates when the research moves.
