Dose with clinical precision.
Coffee is an agricultural product with extreme dose variance. We provide pharmaceutical-grade caffeine and L-Theanine in exact ratios, allowing you to calculate your exact half-life and sleep clearance.
The agricultural variance problem.
A standard cup of coffee can contain anywhere from 75mg to 250mg of caffeine depending on the bean, roast, and extraction method. This variance makes it impossible to accurately predict your daily peak concentration or calculate sleep clearance time. If you cannot measure the input, you cannot control the half-life.
±175mg Variance
A 2014 clinical study found the same size coffee from the same outlet varied by up to 175mg across six consecutive days of testing.
+3.5 Hours
An unexpected high-end dose (250mg) takes approximately 3.5 hours longer to clear to a baseline 50mg than an expected 100mg dose.
-20% Deep Sleep
Residual adenosine receptor blockade at bedtime reduces slow-wave (deep) sleep duration by 20% or more, impairing recovery.
The 1:2 L-Theanine Protocol.
Caffeine is a central nervous system stimulant. Left unopposed, it triggers sympathetic nervous system arousal—the physical symptoms of jitteriness and anxiety. L-Theanine, an amino acid, crosses the blood-brain barrier to increase alpha wave production and GABA levels.
Clinical trials indicate that a 1:2 ratio of Caffeine to L-Theanine (e.g., 100mg Caffeine + 200mg L-Theanine) yields the optimal cognitive profile: heightened alertness from the caffeine, combined with the anxiolytic (anti-anxiety) effects of the L-Theanine, eliminating the peripheral jitter.
- Blunts the sharp noradrenaline spike of unopposed caffeine.
- Extends the perceived duration of cognitive enhancement.
- Prevents the severe energy crash upon systemic clearance.

Calculate your metabolism.
Every individual metabolizes caffeine at a different rate, dictated primarily by the CYP1A2 gene. The average biological half-life is 5 hours, but variations mean it can range from 1.5 to 9.5 hours.
Use our clinical tools to determine your specific clearance rates and schedule doses to ensure your plasma concentration falls below the sleep disruption threshold (usually 50mg) by bedtime.
