Frequently Asked Questions

Go Time is a caffeine-free nootropic designed for sustained mental clarity and motivation without the jitters or "crash" associated with traditional stimulants. It uses Methylliberine and Theacrine for energy, balanced by L-Theanine for calm focus.

It is recommended to take 3 capsules approximately 30 minutes before a cognitively demanding task. To avoid sleep disturbances, do not take it within 8 hours of your intended bedtime.

Users typically experience sharp, productive focus and increased subjective energy and concentration. The presence of L-Theanine helps ensure the energy is "calm and controlled" rather than anxious.

Yes. Do not use Go Time if you are taking mood medications (like MAOIs) without consulting a doctor, as L-Tyrosine can lead to a dangerous increase in blood pressure. Those with hyperthyroidism or Graves' disease should also be cautious, as L-Tyrosine is a precursor to thyroid hormones.

While designed for baseline performance, the usage advice suggests taking at least 2 days a week off to prevent tolerance build-up. Do not exceed two servings (4 capsules) per day.

Even though it is caffeine-free, it contains neuro-activating compounds. Individuals with high sensitivity should start with a single capsule to assess their tolerance.
