Our Door Is Always Open

Greendoor stands for more than cognitive enhancement — it’s a mindset. A willingness to ask better questions, explore smarter solutions, and challenge how we think about mental performance in a demanding world.
We’re not a clinic. We’re not a supplement brand.
We’re a platform built by people who’ve been there — battling brain fog, losing focus, and searching for something more effective than caffeine and wishful thinking.
Why “Greendoor”?
The name reflects a shift — a passage from mental friction to clarity, from conventional thinking to curiosity-driven exploration. Opening the door means choosing to think differently about how we think.
It’s not about chasing perfection.
It’s about reclaiming mental bandwidth.
It’s about being intentional with your brain.
Who We Are
Greendoor was founded by Liam T. Donovan — a nootropics researcher, biohacker, and relentless self-experimenter — after years of digging through scientific papers, testing protocols, and refining what actually works for focus, motivation, and clarity.
But this isn’t about one person. Greendoor is a space for anyone interested in:
- Understanding nootropics without the fluff
- Making informed, ethical decisions about cognitive enhancers
- Balancing ambition with well-being
- Learning from science and real-world experience
Join the Conversation
Whether you’re new to nootropics or deep into self-optimization, we welcome curiosity, skepticism, and dialogue. Greendoor isn’t about telling you what to take. It’s about helping you ask the right questions — and respecting your ability to decide what’s right for you.
The door is open.
