Common questions

Why does my skin tingle?

That's paresthesia — harmless and dose-related. Splitting the dose or using a sustained-release version reduces it.

How long until it works?

Two to four weeks of daily use to saturate muscle carnosine. It is not a pre-workout kick.

Caffeine + L-Theanine

Focused energy without the jittery crash — and coffee counts.

Dose: 100–200mg caffeine with 100–200mg L-theanine.
Skip it if: You're sensitive to caffeine, pregnant, managing anxiety, or training in the evening.

Supplements are optional. Food first — this fills a gap, it doesn't replace meals.
