Powders can be more vulnerable to absorbing trace materials from their environment over time, so we chose glass for its clean, stable, non-plastic storage profile.It is a better way to protect product purity, preserve quality, and stay aligned with the standard we set for everything First Person makes.
Try Think Fast risk-free for 30 days. If you don't feel it from cup one, send the rest back. Full refund. No questions.
THE SCIENCE BEHIND THE CLARITY
A Smarter Form of Lion’s Mane Changes Everything.
Most functional coffees use raw mushroom powder. The problem: powder doesn’t fully dissolve, the taste bleeds through, and absorption is unpredictable. You get an inconsistent experience every time.
Think Fast uses Crystallized Lion’s Mane and a proprietary extraction process that produces the world’s first fully soluble, completely tasteless Lion’s Mane crystal. It dissolves instantly in hot or cold liquid, absorbs faster than any powder alternative, and delivers a precise, consistent dose in every single cup.
The result isn’t just cleaner coffee. It’s a cognitive upgrade that actually works.
Benefits
- Fully soluble with zero grit, zero mushroom taste
- Faster absorption than raw mushroom powder
- Consistent dose, every cup
- Works hot or cold, no stirring required
- Backed by emerging research on neurogenesis and cognitive function

Reaction Time vs Baseline After One Cup
Why Crystallized Lion's Mane Changes Everything.
Fully Soluble
Smooth from the first sip to the last. No grit between your teeth, no muddy residue at the bottom of the cup, no constant stirring to keep it mixed. Just clean café-quality coffee, the way it's supposed to be.
Felt from Cup One
You feel the focus from your very first cup – not three weeks from now. Crystallized Lion's Mane reaches your brain in minutes, not days. The mental clarity shows up when you actually need it.
Consistent Dose
The focus you got on Monday is the focus you'll get on Friday. Every cup delivers the exact same dose — same potency, same effect, same morning ritual you can actually count on.
Completely Tasteless
Zero mushroom flavor. Zero earthy funk. What's left is the premium Costa Rican coffee you came for, nothing else.
One cup. You'll know.
The coffee your morning has been waiting for.

FAQ: Everything you want to know.
Yes, and that's the point. Think Fast is made with single-origin Costa Rican freeze-dried coffee, so it starts with real coffee at its core. No earthy mushroom aftertaste, no artificial masking, no convincing yourself it's worth it. If you love good coffee, you'll love Think Fast.
Most Lion's Mane on the market is a raw powder, poorly absorbed, often gritty, and slow to take effect. First Person's Crystallized Lion's Mane is soluble, tasteless, and bioavailable in a way standard extracts simply aren't. It dissolves completely, leaves no residue, and gets to work immediately. It's not a variation on what's already out there, it's a different category entirely.
Think Fast is a full-strength cup of coffee, intentionally. Two teaspoons in 8–10 oz of water delivers a rich, bold brew closer to a European-style coffee than a diluted brew. If you prefer a lighter cup, simply add more water, pour over ice, or add your milk or creamer of choice. The flavor scales cleanly either way, no bitterness or off-notes, because it starts with premium single-origin Costa Rican coffee. Think of it less like a fixed recipe and more like your coffee, dialed exactly to your preference.
Either, but most people replace their morning coffee entirely. Think Fast delivers the full coffee experience you already love, with the cognitive benefits of Crystallized Lion's Mane built in. One less step, one better outcome.
Most people notice a difference from their very first cup. Think Fast uses Crystallized Lion's Mane, a form developed for immediate absorption, not the standard powders that pass through your system before they can do anything. Sharper focus and clearer thinking, from cup one.
Both work perfectly. Think Fast dissolves completely in hot or cold water, no excess stirring required, no grit left behind. Make it as your morning hot coffee, shake it into cold water for an iced coffee, or blend it over ice. However you take your coffee, Think Fast keeps up.
