A well-formulated pre-workout supplement can turn a sluggish evening session into a PR-shattering workout. Here is how to dose active ingredients and protect your sleep cycles.

1. Optimal Ingestion Window: 25 to 30 Minutes Pre-Training

Caffeine and nitric oxide precursors peak in the bloodstream between 30 and 45 minutes after ingestion. Consume your shake approximately 25–30 minutes before your first working set.

2. Clinically Effective Nitric Oxide Dosages

Look for at least 6 to 8 grams of pure L-Citrulline or 8 to 10 grams of Citrulline Malate 2:1 to ensure sustained vasodilation and muscle oxygenation.

3. Managing Caffeine Tolerance

Every 8 to 10 weeks, switch to a stimulant-free pump formula for 14 days to reset central nervous system adenosine receptors.
