A microdosing “stack” pairs a small dose of psilocybin with supportive ingredients — most famously lion’s mane — for a compounding effect. Here’s what stacking is, how the well-known protocols work, and how the Church’s Red Hail Protocol turns the idea into a structured, guided practice.

Key takeaways

  • A microdosing stack combines a sub-perceptual dose of psilocybin with supportive ingredients — usually lion’s mane, sometimes niacin (vitamin B3) — taken on a set schedule.
  • The best-known version is the Stamets Stack, created by mycologist Paul Stamets: psilocybin + lion’s mane + niacin, on a four-days-on, three-days-off cycle.
  • The Church’s Red Hail Protocol builds on the same principle but structures it into a complete monthly rhythm — measured microdoses on “on” days, a functional-mushroom blend on “off” days.
  • The proposed benefits (neuroplasticity, nerve-growth support) come from early and preclinical research — promising, but not proven in large human trials.
  • Stacking works best with restraint, rhythm, and support — a practice to approach thoughtfully, not a shortcut or a cure.

What is a microdosing stack?

A microdosing stack is a protocol that pairs a sub-perceptual dose of psilocybin — small enough that you don’t trip — with one or more supportive compounds, taken on a deliberate schedule. Instead of psilocybin alone, you take a small, intentional formula on a rhythm.

The idea comes largely from the functional-mushroom world. Lion’s mane is prized for cognitive support; pair it with a psilocybin microdose and, the thinking goes, the parts reinforce one another. “Stacking” simply means combining them on purpose.

Why do people stack?

The rationale rests on three ideas, each tied to one ingredient:

  • Psilocybin → neuroplasticity. Small doses are associated with greater neural flexibility.
  • Lion’s mane → nerve-growth support. It contains hericenones and erinacines, compounds studied for their role in stimulating nerve growth factor (NGF).
  • Niacin (B3) → “delivery.” Some protocols add niacin, which causes a flush by dilating blood vessels; the theory is that it helps distribute the other compounds.

We’ll be honest about the evidence: these are proposed mechanisms and early research, not settled clinical fact. Many people report benefits, and the individual ingredients have supporting studies, but the stacks themselves have not been proven in large human trials.

The Red Hail Protocol: our approach

The Church’s Red Hail Protocol takes the stacking idea and turns it into a complete, repeatable monthly rhythm rather than a loose recipe. Across a 30-day cycle it alternates:

  • “On” days — a measured psilocybin microdose (the sacrament), for the neuroplastic lift.
  • “Off” days — a functional-mushroom and adaptogen blend — lion’s mane, turkey tail, L-theanine, and magnesium glycinate — to support recovery, calm, and focus without psilocybin.

The point of the on/off structure is restraint and rhythm. Microdosing works best with built-in breaks to avoid tolerance, and the off-day blend keeps the practice supportive on the days you’re not taking the sacrament. It’s the difference between guessing at a stack and following a designed protocol inside a supported practice.

What is the Stamets Stack?

The most famous microdosing stack is the Stamets Stack, named for mycologist Paul Stamets. It combines psilocybin + lion’s mane + niacin (vitamin B3), typically on a four-days-on, three-days-off schedule, cycled for several weeks and then paused.

Stamets proposes the three work together — lion’s mane supporting nerve growth, psilocybin supporting neuroplasticity, and niacin acting as a circulatory delivery aid — and has theorized potential for neuron regeneration and cognitive enhancement.

Two honest caveats: Stamets’ mechanism is a hypothesis, not a proven treatment, and the niacin flush is uncomfortable for some people. The Stamets Stack is best understood as the well-known starting point for stacking — the Red Hail Protocol is our structured evolution of the same core idea.

Other ways people stack

Beyond those two, people commonly:

  • Lion’s mane with a microdose, minus the niacin — keeping the cognitive-support pairing without the flush.
  • Adaptogen add-ons — L-theanine for calm focus, or others — which is closer to the Red Hail off-day approach.

Whatever the combination, the durable principle is the same: small doses, a set schedule with real breaks, and supportive ingredients — held with intention.

What stacking is — and what it isn’t

Stacking is a thoughtful practice with a devoted following and plausible, research-adjacent reasoning behind it. It is not a proven medical treatment, a guaranteed outcome, or a reason to take more. The evidence for the individual ingredients is encouraging; the evidence for the stacks as complete protocols is still early. Anyone who tells you a stack will fix a specific condition is moving faster than the science.

How to stack safely

  • Microdose means sub-perceptual. If you feel intoxicated, it’s too much — the goal is barely-there.
  • Build in breaks. Every credible protocol schedules off days to avoid tolerance. More is not better.
  • Mind interactions and contraindications. Psilocybin can interact with some medications (for example, certain antidepressants) and isn’t appropriate for everyone, including some psychiatric histories. Niacin flush can be intense. Talk to a professional.
  • This page gives no prescriptive dose by design. The documented protocols above are described for education; a measured, guided practice — not a number from the web — is how the Church approaches a sacrament.

Our take

We hold to honesty over hype. Stacking is real, the reasoning is sound, and many members find a gentle, cumulative benefit in the practice — but the value was never in chasing a stronger effect or a faster fix. It’s in the rhythm: small, intentional doses, honest breaks, supportive off-days, and a container that treats the sacrament with reverence. That is what the Red Hail Protocol was built to hold. Approach it that way, and the practice tends to give back what you put in.

Frequently asked questions

What is the Stamets Stack?

A microdosing protocol from Paul Stamets combining psilocybin, lion’s mane, and niacin (vitamin B3), usually on a four-on, three-off schedule. Stamets proposes the three support neuroplasticity and nerve growth together, though this remains a hypothesis rather than a proven treatment.

What’s the difference between the Stamets Stack and the Red Hail Protocol?

The Stamets Stack is a recipe (psilocybin + lion’s mane + niacin). The Red Hail Protocol is a complete monthly practice: measured psilocybin microdoses on “on” days and a functional-mushroom + adaptogen blend (lion’s mane, turkey tail, L-theanine, magnesium glycinate) on “off” days, inside a supported, guided structure.

Does microdosing stacking actually work?

Many people report benefits, and the individual ingredients have supporting research, but the stacks themselves haven’t been proven in large clinical trials. Treat it as a thoughtful practice, not a guaranteed outcome.

Why is there niacin in the Stamets Stack?

Stamets includes niacin as a “delivery” aid — it causes a flush that dilates blood vessels, which he theorizes helps distribute the other compounds. It’s optional and uncomfortable for some; not everyone uses it.

Is it safe to take lion’s mane with psilocybin?

Lion’s mane is a widely used functional mushroom and is generally well tolerated. The psilocybin is the part that carries legal and health considerations — see our safety notes and legality guide.

How often do you take a microdosing stack?

On a cycle with built-in breaks. The Stamets Stack uses four days on, three off; the Red Hail Protocol uses a monthly on/off rhythm. Breaks matter — they prevent tolerance and keep the practice sustainable.

The bottom line

Stacking is a simple idea with a devoted following: pair a small psilocybin dose with lion’s mane (and sometimes niacin), on a disciplined schedule, for a compounding effect. The Stamets Stack made it famous; the Red Hail Protocol makes it a structured, supported monthly practice rather than a guess. If you’re drawn to microdosing, the difference that matters most isn’t the exact recipe — it’s doing it with rhythm, restraint, and support.

An invitation

You don’t have to piece a practice together alone. The Church offers the Red Hail Protocol as a guided, measured sacrament, inside a community that treats it with reverence.
