Method

How we judge — before we recommend.

Every protocol discloses how hard we looked, who signed off, and how we make money. Methodology comes before the recommendation, on purpose: you should be able to check our work before you trust the call.

01How hard we looked

Three tiers of rigor.

Every call is tagged with the depth of evidence behind it — so a quick desk read never wears the same authority as a firsthand test.

Tier 1

Desk rigor

A structured read of existing evidence and labels against our checklist. Fast, consistent, and the floor for anything we publish.

Scales infinitely
Tier 2

Evidence synthesis

Pooling the trials ourselves — weighting by quality, dose, and effect size — to reach a call the headline abstract won't give you.

Most protocols
Tier 3

Firsthand test

A rare "hero" test — third-party assays, teardown of a product, or a measured protocol we ran ourselves. Reserved for high-stakes calls.

Where it matters most
02How we say it

Two things, plainly. No stars, no hype.

Every call answers two questions: is the evidence actually there, and what should you do about it. No five-star averages, no "clinically proven" — just where it stands and whether to keep it.

Is the evidence there?

  • Substantiated Strong, replicated, at the stated dose.
  • Mixed Real but conditional — dose, timing, subgroup.
  • Unsubstantiated The claim outruns the evidence.
  • Can't-tell Undisclosed dosing — nothing to judge.

What to do about it

  • Keep Worth taking — buy it.
  • Twin A cheaper equivalent does the same job.
  • Skip Doesn't earn its place — cut it.
  • Nothing The fix is a behavior, not a purchase.
03Who stands behind it

A real name on every call.

The Stack-kit desk

Every call carries the name of the editor who made it and the date it was last checked — so you know who's accountable and how fresh it is. Anything that can interact with a prescription gets a second set of eyes before it goes live.

04How we make money

Reader-funded, and built so a "no" still pays.

The whole business is affiliate commission on the products we'd buy ourselves — at the price you'd pay direct. Integrity is welded into how that works.

No house brands

We don't sell supplements

We have nothing of our own on the shelf, so there's no product we're quietly steering you toward. We point at the best third-party option and earn a small commission if you buy through us.

A "no" still pays

Skip-it routes to buy-this

A negative call isn't a dead end — it routes you to the cheaper twin or the thing that actually works, which we also link. Telling you to cut something costs us nothing, which is why we can.

Same price to you

No markup, ever

Our links are the same price as going direct. The commission comes from the retailer, not from you, and it never changes the dose or the call.

Updated on the record

If a brand slips, we change the call

When a brand's third-party testing changes, we revise the recommendation the same day and email everyone who bought it. Every call has a date for a reason.
