    Summary TheDrug.Wiki

    Arimistane is a suicide aromatase inhibitor banned by WADA and considered unsafe by the FDA for use as a dietary supplement. Run baseline labs before use, then retest estradiol (E2-sensitive LC-MS/MS), total/free testosterone, SHBG, AST/ALT, and lipid panel every 2 weeks during use. Limit cycles to 6 weeks maximum followed by at least 4 weeks off to restore aromatase enzyme levels.

    Tolerance

    Build-up develops within days of regular use; analgesic tolerance faster than respiratory depression tolerance
    Reset 7–14 days for partial reset; full reset may take weeks — tolerance loss greatly increases overdose risk

    Tolerance Decay

    Full tolerance 42d Half tolerance 21d Baseline ~56d

    No formal tolerance data. Timings reflect community patterns (weeks of continuous daily use leading to reduced responsiveness and increased side effects), not receptor-level tolerance. Interpret as practical guidance rather than a pharmacologic model.
