Question 1

How does caffeine improve workout performance?

Accepted Answer

Caffeine acts as a central nervous system stimulant by blocking adenosine receptors (which make you feel tired). Scientifically, taking 3-6mg per kg of body weight has been consistently proven to increase muscular strength, power output, aerobic endurance, and pain tolerance during intense exercise.

Question 2

What does "Caffeine Half-Life" mean?

Accepted Answer

The half-life of a drug is the time it takes for the concentration of that drug in your body to reduce by exactly half. For caffeine in healthy adults, this is typically between 5 to 6 hours. This means if you drink a 200mg pre-workout at 4:00 PM, you still have 100mg active in your system at 9:30 PM.

Question 3

Why does residual caffeine hurt my sleep?

Accepted Answer

Even if you feel like you can fall asleep after drinking coffee, residual caffeine significantly disrupts your sleep architecture. It reduces Slow-Wave Sleep (Deep Sleep), which is the most critical phase for physical recovery, muscle tissue repair, and human growth hormone (HGH) release.

Question 4

What should I do if I work out late at night?

Accepted Answer

If you train within 5 hours of your bedtime, we highly recommend switching to Stimulant-Free (Non-Stim) Pre-workouts. These contain ingredients for pump and focus (like L-Citrulline and Alpha-GPC) but have zero caffeine, protecting your vital sleep and recovery.
