Androsterone is an incredibly versatile prohormone that ultimately converts to stanolone, a.ka. dihydrotestosterone (DHT), which brings some serious muscle-building potential. On top of that, not only is androsterone NOT estrogenic, but it actually exerts some anti-estrogen effects in the body, making this the perfect prohormone to use for lean bulking / cutting cycles.
1 androstene-3b-ol,17-one undergoes a 2-step conversion ultimately transforming into 1-testosterone, a powerful testosterone derivative. Also known as 1-Andro or 1-DHEA, this muscle-building compound does NOT aromatize to estrogen. 1-Andro boasts 1:2 anabolic:androgenic ratio, meaning leaner, drier gains, with little to no fat accumulation during bulking phases
4 androstene-3b-ol,17-one also goes by the names 4-Andro or 4-DHEA. 4-Andro undergoes a 2-step conversion that results in testosterone — the ultimate muscle-building hormone in the body. 4-Andro is known to significantly ramp up appetite, which helps when it’s time to get all those extra muscle-growing calories in!
Arimistane is a powerful suicidal aromatase inhibitor (AI) that reduces circulating levels of estrogen and cortisol in the body. Arimistane blocks the conversion of testosterone to estrogen, significantly boosting natural testosterone production.
