We’re not a supplement company.
We’re not here to sell you hype.
We’re a platform for people who want to think better — on their own terms.
Greendoor exists to help people navigate the complex, often overwhelming world of nootropics, cognitive enhancers, and mental performance tools with clarity, confidence, and context.
We believe that smarter thinking starts with better information — and respect for the brain behind the goal.
What Drives Us
Every day, more people turn to cognitive enhancement to stay focused, recover from burnout, or gain clarity in a distracted world. But many are left guessing — relying on scattered Reddit threads, biased marketing, or trial-and-error experimentation.
That’s where we come in.
At Greendoor, we help people:
- Understand what nootropics do — and don’t do
- Explore cognitive tools ethically and safely
- Separate science from pseudoscience
- Make informed decisions based on personal goals and needs
We serve the curious, the cautious, and the committed — anyone who believes cognitive clarity is worth pursuing, but not worth gambling on.
Our Founder
Greendoor was founded by Liam T. Donovan, a cognitive optimization researcher and nootropics enthusiast who began his journey in response to brain fog, burnout, and the limitations of conventional fixes. After years of experimentation and deep research, Liam built Greendoor to share what works, what doesn’t, and what’s worth questioning.
His approach combines:
- Firsthand experience with compounds like modafinil, racetams, and adaptogens
- Scientific analysis from pharmacology, neuroscience, and biohacking literature
- A people-first mindset grounded in autonomy, safety, and long-term thinking
What We’re Building
We’re not here to dominate the nootropics space. We’re here to raise the standard.
Greendoor is growing into a trusted hub for:
- Research-backed articles and breakdowns
- Personal protocols and recovery strategies
- Ethical frameworks for mental enhancement
- Tools for clearer thinking — and clearer decision-making
Who we are is simple:
People who believe cognitive enhancement should be informed, ethical, and accessible — for anyone ready to think a little more clearly, and live a little more fully.
