Arimistane 101: How To Use It Correctly, Dosages & More!

Arimistane is a aromatase inhibitor. It also goes by the name Androsta 3, 5-dien-7, 17-dione or Androsta. It is available over the counter at several online stores and doesn’t require a prescription.

What this compound does is that it helps lower a hormone called estrogen. Too much estrogen in men can cause issues such as gynecomastia, fat gain and more.

Long story short, you don’t want your estrogen to get too high. This is where aromatase inhibitors (AI’s) step in to prevent it from getting to high.

Let’s take a look at the best ways to use Arimistane for optimal effects and results.

How To Use Arimistane

There are several different ways to use Androsta 3, 5-dien-7, 17-dione. You can use it standalone, for gyno or as a Post Cycle Therapy.

Let’s take a look at the different options. 

Arimistane Standalone

A lot of people use this compound standalone. It is mainly because it’s also effective at raising testosterone levels. 

Blocking estrogen will cause testosterone to increase. More testosterone will lead to faster muscle and strength gains.

It’s also highly effective for stubborn fat loss. If you’re struggling with getting the fat off in the common trouble areas such as love handles, give Arimistane a try.

Arimistane For Gyno

Gynecomastia or also referred to as Gyno is pretty common amongst bodybuilders. It’s basically breast tissue beneath the nipple that is swelling up.

This compound can help with gyno as it might be able to reverse it. I’ve seen a lot of people that have used Arimistane for Gyno with good results.

It is not guaranteed to work but, in my opinion, it is always worth trying before considering the alternatives.

Post Cycle Therapy

For SARMs and Prohormones cycles, Arimistane is a mild yet effective Post Cycle Therapy and Anti Estrogen comound.

Once the cycle is completed, you run it for 30 days to help your testosterone levels bounce back up. 

In the Rebirth PCT, you’ll find many key ingredients including Arimistane (Androsta 3, 5-dien-7, 17-dione) making it a great over the counter PCT supplement.

Personally, I always use Rebirth PCT after my cycles because it helps me maintain mass and strength.

If you’re in need of an effective supplement containing Armistane, I definitely suggest checking it out. You can also use it as a SARMs PCT.

Arimistane Dosage

Of course, it’s going to be important to know what the most optimal arimistane dosage is.

But first, it’s advised to start out with a low dosage since this compound can crash estrogen levels if you take too much.

Generally, the optimal arimistane dosage is between 25-75mg per day. Again, it’s advised to start out with just 25mg per day to see how your body reacts to it.

A PCT cycle with this compound usually lasts about 4 weeks (30 days). This should be plenty of time for your body to recover from a mild cycle.

When using it standalone, it’s also advised to run it for 1 month. During this period, you’ll notice increased lean muscle mass, strength and performance.


Does Arimistane Have Side Effects?

Yes, Arimistane can have side effects when it is not used correctly.

This is why I hammer on the fact that you need to start out with a low dosage. For example, the first days of your cycle just take 25mg per day.

Once you feel comfortable enough you can increase to 50mg per day with a maximum of 75mg per day.

What happens when you take too much? Well, you can end up crashing your estrogen. And trust me when I say that is something you don’t want happening.

So guys, be smart. Start with a low dosage and you’ll be completely fine and experience no side effects. It’s a great estrogen blocker when used correctly.


Androsta 3, 5-dien-7, 17-dione (Arimistane) is a great compound that can be used in many different ways.

If it’s used correctly, you should be able to experience significant results. Make sure to start out with a low dosage and go from there.

One of the best supplements containing this compound is Rebirth PCT. It also contains several other ingredients that have shown to boost testosterone.
