Founder's Note
Why I built this
A year ago, I started lifting. The trigger is still hard to talk about — something personal. I realized I was weak, and I needed to get stronger somehow. So I picked up the barbell.
The first months were brutal. I couldn't bench 40kg. I was the skinniest guy at the gym. I had to eat more than I wanted, and meals stopped being fun. I kept thinking: how can I work this hard and see nothing?
Then, around month two, my body started changing. But what changed more wasmy relationship with myself. The more real fear I faced at the gym, the smaller my everyday anxieties felt. Work, relationships, awkward conversations — they all shrank next to a heavy bench press.
Along the way, I spent dozens of hours choosing supplements. YouTube breakdowns, Reddit threads, Japanese comparison sites. Too much information — I got lost. Extreme opinions canceled each other out. I didn't know what was true anymore.
Forgestack is the tool I wanted back then. We don't inflate claims. We don't push weak-evidence supplements as 'the answer.' We run on affiliate commissions that don't change your price — and we protect your time and your judgment.
Training can change your life. I won't let you waste that first step on supplement confusion. That's why this exists.
FAQ
Frequently asked questions
Common questions before you start with Forgestack.
Is the Forgestack quiz really free?+
Completely free. No signup or email required — your answers stay in your browser. The service runs on affiliate commissions paid by retailers, which never affect what you pay.
Where can I check the science?+
Each supplement detail page cites the underlying research with PubMed links — Morton 2018 (BJSM), Kreider 2017 (ISSN Position), Martineau 2017 (BMJ), and more. The articles section has deeper dives per supplement.
Are rankings influenced by affiliate commissions?+
No. Recommendations are computed from evidence strength, safety, budget fit, and goal alignment. Affiliate commission rates never enter the calculation. This is also stated in our terms.
Can I use the quiz if I have health conditions or take medication?+
You can use the quiz, but results are reference only. If you have health conditions, take medication, are pregnant, or are a minor, consult a physician or pharmacist before starting any supplement. Forgestack is not medical advice.
Can I re-take the quiz?+
Yes. Retake it anytime your training or goals shift — we recommend every three months. Previous answers aren't saved, so each run is fresh.
How is this different from other supplement quizzes?+
Forgestack grounds every recommendation in peer-reviewed science and your answers alone — no vendor bias, no stock-driven picks. We list multiple retailers per pick and publish side effects, drug interactions, and cited papers for every recommendation.
