What Is Arimistane?

Before introducing you to some of the most effective Arimistane supplements, it's essential to learn more about the compound and what it can do for you.

Androsta-3 5-diene-7 17-dione, also known as Arimistane, is an aromatase inhibitor. These compounds have been created to reduce the amount of estrogen production while increasing natural testosterone production.

This can be beneficial for athletes because an increase in testosterone levels will positively impact lean muscle mass, recovery rate, strength, and libido.

Many users take this compound to combat estrogen-related side effects or as a Post Cycle Therapy.

We're going to show you everything you need to know about this product.

What Is Arimistane Used For?

Androsta-3 5-diene-7 17-dione can be used for different purposes, depending on your goals. It's one of the very few over the counter aromatize inhibitors making it a unique product.

We will be going over the different ways you can effectively use this product.

Post Cycle Therapy

Another popular way Arimistane is being used is as a post cycle therapy protocol. A post cycle therapy is run after a SARMs, prohormones, or steroid cycle to help your body restart its natural hormone production.

As you now know, Androsta-3 5-diene-7 17-dione blocks estrogen, which could lead to an increase in natural testosterone.

Since your testosterone will be suppressed after a cycle, it's precisely what you'll need to recover. It can help increase your test levels, allowing you to maintain gains, energy, and libido.

Make sure to check out our PCT Stack, a combination of the Enhance testosterone booster and Rebirth PCT.

It's a mild and effective way of running a PCT. We've done a write up on how to run a post-cycle therapy and give it a read.


Many users run Arimistane standalone, meaning they don't stack it with anything else.

The main reason athletes do it is to help them increase performance due to the increase in testosterone.

High testosterone levels can be very beneficial for bodybuilders because they have a direct effect on skeletal muscle.

Arimistane for bodybuilding

And not just will it help enhance your muscle mass, it can also boost power, strength, and libido. It's a great product, and if you're looking to boost your progress, you should consider running Arimistane standalone.

It is optional to stack it with other muscle-building supplements such as Laxogenin or Epicatechin.


Gyno, short of gynecomastia, is when breast gland increases in men. Of course, this is something you're going to want to avoid getting.

Many users take Arimistane to help prevent, reduce, and in some cases, even reverse gyno.

High levels of estradiol often cause gynecomastia. Since this compound could block estrogen, it might be a useful product to test.

Arimistane Dosage Information

As with any other types of bodybuilding supplements, we advise starting with a low dosage to assess tolerance.

Based on user reports and research, Arimistane works best at a dosage of 50 to 75mg per day.

New users should start with a lower Arimistane dosage of 25mg per day to see how they react to it.

Since it's an aromatase inhibitor that reduces estrogen, you don't want to take too much.

Our product, Rebirth PCT, contains 12,5mg per capsule, making it easy for you to find the sweet spot dosage-wise. If it's your first time taking this compound, you can start by taking one to two capsules.

From there on, you can gradually increase to the recommended serving size of 6 capsules.

The Half-Life Of Arimistane

The half-life of Arimistane (Androsta-3 5-diene-7 17-dione) is said to be between 2 to 4 hours. Due to the short half-life, it is recommended to spread your dosage throughout the day.

By spreading the dosage, you will be able to maintain this compound's stable levels in your system.

Will Arimistane Cause Side Effects?

Since this product is an aromatase inhibitor or estrogen blocker, taking too much could make your estrogen drop too much, which should be prevented at all costs.

Start with one capsule of Rebirth, which contains 12.5mg for a few days. If all goes well, increase to two capsules and so on until you reach your sweet spot.

It is essential to make sure that you are staying within dosage guidelines. By doing so, you should not experience any side effects.
