Want to increase your gains and size? 4-Andro or 4-Androsterone can deliver those desired results. 4-Andro converts into testosterone (which is the place of origin of all gains) once consumed.

Let’s take a closer look at 4-Andro to know what it is, how it works and everything there is to learn behind this potent agent!

Before we start, let’s understand what Androsterone is…

Androsterone or 3α-hydroxy-5α-androstan-17-one is a steroid hormone created in the liver from the metabolism of testosterone. It is an androgen which fuels the growth or preservation of masculine features – including muscle mass increase. The most recognized androgen is testosterone.

What Is 4-Andro?

4-Andro, also known as 4-DHEA is an anabolic prohormone that leads to incredible increases in muscles mass and strength levels. With its proven results, it is one of the best bodybuilding supplements available in the market today. It enables the users to enjoy the benefits of dehydroepiandrosterone (DHEA) without having to face nasty side effects of high estrogen level. DHEA is basically a hormone responsible for increasing muscle size and mass and is produced in the adrenal gland, located at the top of our kidney. The adrenal gland is responsible for producing most of the important hormones of our body that regulate our cortisol and sexual functions. These hormones also play a vital role in maintaining good health.

The hormone DHEA is primarily produced by adrenal glands but our brain also produces it. This hormone stimulates the production of estrogen and androgen, which is a great benefit for those willing to increase muscle mass and size. However, as a person ages, the natural production of DHEA in the body reduces. This reduction in DHEA results in various hormonal disorders, osteoporosis (bone disease), and disturbed sexual function.

4-Andro is a prohormone that plays an essential role in stimulating androgenic activity and may also restore DHEA to natural levels in the body. This prohormone remains inactive until it is required by the body. It is triggered by the processes when it is needed.

We have used the word “prohormone” repeatedly up till now. So if you’re wondering what a prohormone basically is, it is a hormone precursor that helps us maximum benefits from the naturally produced hormones. They are taken orally and are ineffective on their own. They are circulated in the body via the bloodstream and are converted into hormones. Once they are converted, they regulate the natural hormone levels in the body. For example, a prohormone that after circulating in the bloodstream is converted into protein helps the athletes in improving their muscle health and performance. 4-Andro is basically such kind of a prohormone.

How Does 4-Androsterone Work?

4-Andro provides quick and massive muscle mass gains and also increases aggression. It is non-methylated prohormone and therefore is mild and safe to use. 4-Andro converts into testosterone in two steps. It is first converted into 4-Androstenediol and then in the second step, into testosterone. During this process, 4-Andro molecules get attached to an ester (an anabolic steroid present in the body) that speeds up the conversion of 4-andro into testosterone. In this way, you feel anabolic effects faster and these effects stay in your body for a longer period of time.

Once the conversion of 4-andro into testosterone has taken place, you will start feeling androgenic and anabolic effects significantly. This means that you will experience considerable increases in your strength levels and muscle mass. The reason behind these massive muscle gains and increased strength is the improvement in protein synthesis that has taken place due to the conversion of 4-Andro.

However, 4-Andro does not have fat-cutting or calorie burning properties. Thus this prohormone results in muscle and strength gains, as well as weight gain.

4-andro is a highly potent prohormone and therefore provides quick results. This is the reason why you shouldn’t cycle with this prohormone for more than a month or two.  Within the first few weeks, you will start noticing changes in your muscles and overall muscular look. You will also feel (more energized and your recovery time will become shorter.

Proper Dosing of 4-Andro

  • The recommended dosage for experienced users is 300-750 mg per day split in intervals. The optimal cycle duration for them is 6-8 weeks.

You can split your daily dose into two parts. Take one part in the morning and the other in the evening. Or, another way to split your dose, which will also help you get maximum benefits, is to take one part pre-workout and the other one before going to bed. This ensures maximum strength increase and muscle growth, as well as quick recovery.

Make sure that you follow these guidelines as 4-andro is a highly concentrated prohormone and isn’t one of those you can experiment with. Moreover, you can expect a muscle growth of around 8-10 pounds if you follow these guidelines properly.

Possible Side Effects (And How To Avoid Them)

Being a non-methylated prohormone, 4-andro is not harsh on the liver like most of its counterparts are. Also, it does convert into estrogen but the conversion is very mild. Thus you won’t have to worry much about the estrogenic effects such as gyno etc.

However, this prohormone does have a few side effects, which includes:

  • Increased aggression
  • Acne
  • Slight testosterone suppression
  • Back pumps
  • Muscle cramps
  • High blood pressure
  • Gynecomastia, in very rare cases

Although 4-andro’s conversion into estrogen is very mild, it is still recommended to use estrogen blockers in order to prevent gyno and curtail other estrogenic effects such as bloating etc.

Moreover, these above-mentioned side effects can be controlled by taking proper on-cycle support, and medication for blood pressure. Also, take vitamin supplements and follow the recommended dosage guidelines. In this way, you’ll save yourself from most of the side effects that are likely to occur with 4-andro’s use.

Does 4-Androsterone Require On Cycle Support and PCT?

It is highly recommended to go for a proper post-cycle therapy after completion of your cycle. PCT stabilizes and restores your body’s overall health and brings your hormonal levels back to their natural state.

When we intake a prohormone, the natural production of hormones in our body is disturbed and sometimes lead to quite nasty side effects. To restore the natural level of hormone production, PCT is used.

In addition, PCT also helps in maintaining your gains for a longer period of time. You surely don’t want all your efforts to go waste, so make sure to go through a proper post-cycle therapy after your cycle has been completed.


Well, honestly speaking, yes. But it’s different from the regular steroids as it is legal in the U.S.

The reason is that 4-Andro provides the benefits of 4-DHEA, which is also naturally produced by our body. In fact, it is one of the most abundantly present steroids in our body that are naturally produced by our adrenal glands and brain. 4-andro converts into testosterone and enters our bloodstream. Our body then uses it like the naturally produced testosterone. However, it does not harm your liver and thus you shouldn’t worry much about it being a steroid.

Yes, 4-andro can be easily stacked with almost every other prohormone. However, the best options to stack it with are dry compounds such as Epi-Andro and 1-Andro. These dry compounds work amazingly well with 4-Andro as they reduce or prevent water retention in the body. Due to reduced water retention, the muscle gains are dry and thus it is easier for the user to maintain his gains. Also, it is quite clear to him that the muscle mass and size he has gained is not due to water in his body.
