Common dosing range
50–200 mg per serving (often with caffeine); blends cap near 250 mg/day
When to expect effects
Within an hour (acute)
Watch out for
Stacked with caffeine and theacrine it adds cardiovascular load; caution in hypertension or arrhythmia
What is it
Methylliberine (2-methoxy-1,7,9-trimethylpurine-6,8-dione, trade name Dynamine) is a methoxylated purine alkaloid structurally related to caffeine and theacrine, naturally occurring in trace amounts in Coffea and kucha (Camellia assamica var. kucha) tea. It is hypothesized to act as a non-selective adenosine receptor antagonist and dopamine reuptake modulator, with anecdotally faster onset than caffeine.

acute energy and focus
Supplement benefitMethylliberine (Dynamine) is a purine alkaloid related to caffeine and theacrine, proposed to antagonize adenosine receptors and modulate dopamine signaling. The limited human evidence comes mostly from short studies combining it with caffeine, where hemodynamics and labs stayed stable but isolated efficacy was not robustly demonstrated. Effects on energy and focus are plausible but under-characterized.
Bottom line: A plausible short-acting stimulant adjunct, but human efficacy evidence is thin.
Evidence is mixed
Most data study methylliberine combined with caffeine, so its standalone contribution to energy and focus is hard to isolate.

Common side effects
Serious risks
Added cardiovascular load when stacked with caffeine and theacrine
Who should avoid it
- People with hypertension or arrhythmia

- Pregnant or breastfeeding women
Pregnancy & breastfeeding
Avoid; no safety data and it adds stimulant load.
Interactions
Additive cardiovascular and CNS stimulation, raising heart rate and blood pressure.
Combined stimulation may increase cardiovascular strain.
