Comparison
Bromantane vs Clomiphene
Side-by-side of Bromantane and Clomiphene. 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.
Clomiphene
Clomiphene citrate raises LH/FSH and endogenous testosterone in men. SERM TRT alternative, 25 to 50 mg, fertility preserved, visual side effects flagged.
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
Clomiphene
- •SERM that blocks estrogen-receptor negative feedback at the hypothalamus, raising LH and FSH
- •FDA approved 1967 for ovulation induction in anovulatory women at 50 to 100 mg cycle days 5 to 9
- •Off-label in men at 12.5 to 25 mg daily raises endogenous testosterone while preserving fertility
- •Enclomiphene (trans-isomer) is preferred for male use; cleaner PK and less estrogenic side effect burden
- •Visual disturbances occur in ~1 to 2% of users; persistent symptoms warrant immediate cessation
- •Letrozole has displaced clomiphene as first-line ovulation induction in PCOS (Legro 2014)

Contraindications
- pregnancy

Interactions
- MAOIs: theoretical additive dopaminergic and serotonergic activity(major)

Interactions
- tamoxifen: competing SERM activity; not used together(moderate)
- ospemifene: competing SERM activity(moderate)

- TRT (exogenous testosterone): TRT suppresses HPT axis that clomiphene targets; do not combine(moderate)
Which Should You Take?
Clomiphene comes out ahead for most readers on the criteria we weight: 2 catalogued goals, prescription-only, oral dosing, with a Tier-A 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 hormonal optimization, pick Clomiphene.
- → If your priority is fertility, pick Clomiphene.
Edge case: Clomiphene is contraindicated in pregnancy; Bromantane is the safer pick if that applies.
Default choice: Clomiphene. Wider use case, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for Bromantane only if your priority sits squarely in the goals it owns above.
