Comparison
Bromantane vs EGCG
Side-by-side of Bromantane and EGCG. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Bromantane
Bromantane, the Russian nootropic sold as Ladasten (ADK-709), acts on dopamine to cut fatigue and anxiety without classical stimulant rebound.
EGCG
EGCG supplement guide: 300-600 mg/day green tea catechin for fat loss and cardiovascular markers. Hepatotoxicity risk above 800 mg/day fasted.
Effects at a glance
Bromantane
- •Russian RCT base (Voznesenskaya 2010, n=728) supports 50 mg daily for asthenia and fatigue over 4 weeks
- •Atypical actogenic mechanism: induces tyrosine hydroxylase rather than direct monoamine release
- •Subjective profile is anxiolytic plus mildly motivating, distinct from classical stimulants
- •Long half-life of around 11 hours supports once-daily morning dosing
- •WADA-banned since 1996; relevant for tested athletes
- •Western evidence base is thin; most published trials are Russian-language and not independently replicated
EGCG
- •Modest fat loss (~1.3 kg over 12 weeks) when combined with caffeine and caloric deficit
- •Small reductions in LDL cholesterol (3-6 mg/dL) and systolic blood pressure (2-3 mmHg)
- •EFSA flags hepatotoxicity risk above 800 mg/day, particularly when taken fasted
- •Bioavailability is 0.1-1.0%; gut microbiome variation drives population-variable response
- •Green tea extract typically combines EGCG with caffeine and L-theanine for additive effects
- •Reduces non-heme iron absorption when co-administered with meals

|---|---|---|
| Category | nootropic | natural |
| Also known as | Ladasten, ADK-709, N-(4-bromophenyl)adamantan-2-amine | epigallocatechin gallate, green tea extract |
| Half-life (hr) ↗ | 11 | 3 |

| Molecular weight | 280.21 | 458.37 |
| Molecular formula | C16H20BrN | C22H18O11 |
| Mechanism | Indirect dopaminergic and serotonergic actogenic activity via induction of tyrosine hydroxylase and selective increases in serotonin synthesis in hippocampus and hypothalamus. | Inhibits catechol-O-methyltransferase (COMT) to prolong norepinephrine signaling; activates AMPK; scavenges reactive oxygen species via gallate ester; modulates gut microbiome and pancreatic lipase activity. |
| Legal status | Approved in Russia (Ladasten); unscheduled and unapproved in US, EU, UK | Dietary supplement; warning labels required above 800 mg/day in some EU jurisdictions |
| WADA status | banned | allowed |
| DEA / Rx | Not scheduled in the US | Not scheduled |
| Pregnancy | Not recommended | Avoid high-dose extracts; moderate green tea consumption appears acceptable |

- classical stimulants: theoretical additive activity, undocumented(moderate)
EGCG
Common side effects

- anticoagulants: additive effects at high catechin doses(minor)
- beta-blockers (nadolol): reduced absorption when taken simultaneously(moderate)
- hepatotoxic supplements (high-dose niacin, kava): theoretical additive hepatotoxicity at high EGCG doses(moderate)
- stimulants and caffeine: additive thermogenic and cardiovascular effects(minor)
Which Should You Take?
EGCG comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. Bromantane is the right call when one of the conditionals below applies.
- → If your priority is focus or working memory, pick Bromantane.
- → If your priority is fatigue resistance, pick Bromantane.
- → If your priority is metabolic health and glucose control, pick EGCG.
- → If your priority is healthspan extension, pick EGCG.
Edge case: If you want to avoid controlled substance, EGCG is the more accessible choice.
Default choice: EGCG. Lower friction to source, and broader goal coverage. Reach for Bromantane only if your priority sits squarely in the goals it owns above.

Which has a longer half-life, Bromantane or EGCG?
Bromantane half-life is 11 hours; EGCG half-life is 3 hours.
Can you stack Bromantane with EGCG?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
