Antiestrogens, also known as estrogen antagonists or estrogen blockers, are a class of drugs which prevent estrogens like estradiol from mediating their biological effects in the body. They boost up testosterones that helps in muscle gain. This article is regarding to Arministane which is strong and legal aromatase inhibitor and anti estrogen supplement.

What is Arministane

The generic name of arministane is 1,4,6-Androstatriene-3,17-dione (ATD) is a potent irreversible aromatase inhibitor. It is used to help control estrogen levels. Basically, it helps prevent Testosterone from converting into estrogen. ndrosta 3, 5-dien-7, 17-dione is also used to help combat aromatazation from prohormones and other performance enhancers.

How it Works

Testosterone is responsible for increased muscle mass. Leaner body mass helps control weight and increases energy. For men with low testosterone, studies show that treatment can decrease fat mass and increase muscle size and strength. Some men reported a change in lean body mass but no increase in strength. Testosterone increases neurotransmitters, which encourage tissue growth. It also interacts with nuclear receptors in DNA, which causes protein synthesis. Testosterone increases levels of growth hormone. That makes exercise more likely to build muscle.

The dosage for Arimistane is anywhere from 25 to 75mg per day

Most propose a greatest portion of ~75mg/day of arimistane, typically split into three 25mg dosages for the duration of the day for 4 to 6 weeks. While 75mg is the most usually proposed dosing, this more than likely is an aftereffect of the significant expense of this crude material, and dosages up to 150mg/day may expand benefits. You have to be careful with dosing Arimistane (Androsta 3, 5-dien-7, 17-dione). You definitely don’t want to crash your estrogen because this can cause side effects.

Half Life

Based on my research, it has a half-life of roughly 2 to 3 hours. This means that it should be dosed multiple times per day to maintain stable levels in the system.

Side Effect

Using too much of this compound might crash your estrogen which is something you don’t want happening. Arimistane acts as a “suicidal inhibitor” of the aromatase enzyme, meaning once it binds, it is incapable of releasing until the body eliminates the enzyme from the body. As such, this compound will directly cause decreased estrogen levels while simultaneously increasing testosterone levels making a great option for use on its own, or after prohormone cycles as a PCT. It also causes bone loss and dries joints.  As long as you stick within the recommended dosage guidelines you should fine.
