|---|---|---|
| Half-Life | 11-12 hours | 2-4 hours (asiaticoside, madecassoside) |
| Typical Dosage | Standard: 50-100 mg once daily in the morning. Start with 50 mg. Do not exceed 100 mg daily. Can be taken sublingually for faster onset. | Standard: 500-1000 mg standardized extract daily (triterpenes: asiaticoside, madecassoside). Traditional dose: 1-2 grams dried herb as tea. ECa 233 is a well-studied standardized extract. Can be taken morning or evening — mild enough for bedtime use. |

Mechanism of Action
Bromantane
Bromantane upregulates tyrosine hydroxylase (TH)—the rate-limiting enzyme in catecholamine synthesis—and aromatic L-amino acid decarboxylase (AADC), the enzymes responsible for converting L-tyrosine to L-DOPA and then to dopamine. This increases neuronal dopamine production capacity rather than depleting vesicular stores like traditional stimulants. The mechanism may involve modulation of transcription factors or enzyme phosphorylation. Bromantane also has anxiolytic properties through enhancement of GABAergic transmission, possibly via GABA-A receptor modulation or increased GABA synthesis. The combination of upregulated dopamine synthesis in mesolimbic and nigrostriatal pathways with GABAergic dampening of anxiety circuits produces sustained motivation, focus, and reduced mental fatigue without the jitteriness or crash typical of dopamine-releasing agents.
Gotu Kola
Triterpene saponins (asiaticoside, madecassoside, asiatic acid, madecassic acid) are the primary bioactives. They increase BDNF expression in the hippocampus via CREB and ERK/MAPK pathways, promoting neuroplasticity, synaptogenesis, and memory formation. They enhance collagen type I synthesis through stimulation of fibroblasts and improve microcirculation via VEGF and angiopoietin modulation. Anxiolytic effects occur through positive allosteric modulation of GABA-A receptors (possibly at the benzodiazepine or neurosteroid site) and reduction of acoustic startle response (amygdala modulation). Gotu kola inhibits acetylcholinesterase (AChE), mildly increasing synaptic acetylcholine. Anti-inflammatory effects come from NF-kB inhibition (IkB stabilization) and TNF-alpha suppression. Asiatic acid may also activate PPAR-gamma.
Risks & Safety
Bromantane
Common
Mild stimulation, restlessness, insomnia if taken late.
Serious
Very limited Western safety data. Most research is from Russian military/sports studies.
Rare
Headache, irritability, increased anxiety in some individuals.
Gotu Kola
Common
Very well-tolerated. Mild GI upset, drowsiness.
Serious
Rare hepatotoxicity reported — avoid with liver disease and limit use to 6-week cycles.
Rare
Headache, dizziness, skin sensitivity to sunlight.
Full Profiles
Bromantane →
A unique Russian-developed compound that is both an adaptogen and a mild stimulant — it enhances dopamine synthesis (upregulating tyrosine hydroxylase) rather than releasing or blocking reuptake of existing dopamine. This makes it fundamentally different from traditional stimulants and gives it a smoother, less addictive profile. Used by Russian athletes until WADA banned it.
Gotu Kola →
Centella asiatica is an Ayurvedic and Chinese medicine herb known as the 'herb of longevity.' It has been used for centuries to enhance memory, promote wound healing, and reduce anxiety. Modern research confirms it increases BDNF, enhances collagen synthesis, improves microcirculation, and has anxiolytic effects. Unlike most adaptogens, gotu kola has clinical evidence for improving memory and attention in healthy adults.
