Proven Benefits

01May increase subjective energy

02May improve cognitive performance

03May enhance mood

Chemical Forms

Recommended

Dynamine (methylliberine)

Avoid

Unstandardized kucha tea extracts (unknown alkaloid content)

Expert Note

Dynamine is a standardized preparation of methylliberine, ensuring consistent dosing. Non-standardized herbal sources like raw kucha tea vary widely in alkaloid content and may deliver unpredictable amounts of caffeine and other xanthines.

Protocol

Amount

100-200 mg

Frequency

Once daily, or only as needed

When

Morning or early afternoon; avoid within 8 hours of bedtime due to stimulant effects.

Condition-Based Dosing

First-time or stimulant-sensitive users

50 mg to assess tolerance before increasing— Effects are highly individual; some users report jitters at standard doses.

Experienced caffeine users seeking acute focus

100-200 mg, taken as needed— Do not exceed 300 mg/day; data beyond 8 weeks of daily use are lacking.

Safety & Limits

Upper Safe Limit

300 mg/day (highest dose studied in short-term human trials)

Cycling

4 weeks on, 1-2 weeks off; or use only on demanding days rather than daily.

Contraindications

Pregnancy or breastfeeding — stimulant safety not established

Cardiovascular disease or arrhythmias — may increase heart rate and blood pressure

Anxiety disorders or panic disorder — may worsen symptoms

Bipolar disorder or mania — stimulants may trigger mood episodes

Hypertension — uncontrolled blood pressure may be aggravated

Concurrent use of prescription stimulants (e.g., amphetamines, methylphenidate) — additive effects and cardiovascular risk

Synergies

Caffeine

Caffeine appears to complement methylliberine's adenosine blockade, with some studies using the combination.

L-Theanine

L-theanine can smooth the stimulant edge and reduce jitteriness.

Avoid Combining With

✕Other stimulants (additive cardiovascular load — monitor total daily stimulant intake)
✕Alcohol (may mask intoxication and increase risky behavior)
✕Late-day dosing (disrupts sleep architecture)
