Our Door Is Open to Independent Thinkers

Written byLiam T. Donovan

Greendoor began with a simple question:
What if thinking better didn’t have to be guesswork?

In a world full of pressure, burnout, and noise, we believe clarity is one of the most valuable resources a person can have. Whether you’re new to nootropics or already experimenting with cognitive enhancement, our door is open to you.

What Greendoor Stands For

We’re not here to sell you hype. We’re here to help you explore:

  • How cognitive enhancers actually work
  • What science supports (and what it doesn’t)
  • How to use nootropics responsibly, effectively, and on your own terms

This isn’t about chasing superhuman status. It’s about reclaiming your focus, your energy, and your ability to think clearly — with autonomy and intention.

Who We Are

Greendoor was founded by Liam T. Donovan, a researcher and nootropics enthusiast who’s spent the last 8 years testing, documenting, and decoding the world of smart drugs and cognitive enhancers. His goal — and ours — is to empower others through honest insight, practical tools, and science-backed exploration.

We’ve built this platform for:

  • Students navigating academic overload
  • Professionals managing cognitive fatigue
  • Biohackers refining their stacks
  • Everyday people asking, “How can I function better?”

Step In

Curious. Skeptical. Burned out. Driven. Wherever you’re coming from, if you’re ready to understand your brain better — and make smarter choices about how you support it — you’re in the right place.

Welcome to Greendoor.
Where thinking better starts with asking better questions.
