How to Choose

Pick stim or stim‑free based on tolerance and training time. Then check effective doses and certifications.

If you train late or are sensitive to caffeine, go stim‑free and add a nitrate shot for performance.

Take 30–60 min pre for caffeine‑based products; nitrates ~2–3 h pre. Consistency beats novelty.

Creatine daily (3–5 g). Stim‑free pre (citrulline + betaine) + nitrate shot is a strong combo without caffeine.

Seek transparent labels with clinical doses. Avoid proprietary blends and excessive sweeteners.
