4 Andro, short for 4-Androsterone, is a type of chemical classified as a prohormone.1

Prohormones include testosterone and are often regarded as the “muscle-building” hormones of the human body.

Today, athletes and bodybuilders can turn to muscle-building supplements like 4 Andro to produce the results they need in the gym.

4 Andro is capable of helping you burn excess fat, build lean muscle, inherit more strength and power, as well as improved recovery.2

Let’s review the primary benefits of taking 4 Andro:

  • Increases Muscle Tissue
  • Improves Strength & Power
  • 2-Step Testosterone Conversion
  • Enhances Recovery Time

It’s important to note that 4 Andro is a legal, non-methylated prohormone.

The anabolic properties assist with muscle growth and improve physical performance.

While the substance is not considered toxic to the liver there are still some precautions to consider.

First, there is little evidence to support the use of 4-Andro (4-DHEA) in a clinical setting until more research is conducted.

Secondly, most of the research that has been done on 4 Andro and other prohormones is largely limited to animal studies.

Consequently, we suggest that you speak to a physician before starting any new weight stack or prohormone supplementation.

Nonetheless, 4 Andro remains one of the few legal prohormones on the market.

More Detailed Benefits of Taking 4 Andro

4-Androsterone (4-DHEA), or 4 Andro, has gained momentum in the world of weight stacks.

There are many that consider it one of the more mild prohormones (in terms of nasty side effects, more information below) yet still effective at producing muscle growth. 

Therefore, 4 Andro can help you burn fat and gain bulk muscle without needing to rely on more powerful and damaging performance-enhancing drugs.

Additionally, the prohormone offers several other benefits that we’ll review in more detail:

4 Andro Increases Muscle Tissue

4-Androsterone (4-DHEA) is a prohormone that helps improve testosterone levels.

Testosterone is crucial to muscle growth and improving strength/power.

As a result, 4 Andro is commonly used in weight stacks with other muscle-building supplements such as RAD 140 and S-23.

Supplements like Behemoth Labz 4 Andro utilizes 2-step testosterone conversion technology.3

The approach helps maintain healthy testosterone levels necessary for men to achieve their fitness goals.

4 Andro Increases Strength & Power

4-Androsterone is not just simply a muscle growth stimulant.

In fact, the prohormone can also help you feel stronger and more powerful in the gym.

The 2-step testosterone conversion and improved recovery times help you feel reinvented.

It’s especially powerful when stacked with other lean muscle and fat-burning supplements (more information, below).

With that said, some studies have concluded that there are no noticeable effects from supplementation.4

4 Andro Enhances Recovery

You’ll spend less time recovering between workout sessions with 4-DHEA.

The prohormone supplement for muscle growth produces less fatigue and pain as you adjust to a new workout routine and cycle.

Additionally, the compound is non-methylated as well as considered non-toxic to the liver.

Thus, 4 Andro can help you bulk up faster with lean muscle since you’ll spend less time recovering from the sideline.

4 Andro Dosage and Cycle Instructions

There are different opinions on the correct dosage and cycle length for prohormone supplements like 4 Andro.

Nevertheless, most suggest a cycle that lasts between 6 to 8 weeks.

More importantly, those that are new to 4-Androsterone (4-DHEA) supplements may want to limit the cycle to 6 weeks.

Secondly, fitness experts and workout enthusiasts have varying suggestions on daily dosage.

Those that have cycled with 4-Androsterone or other prohormones may take anywhere from 100-200mg of 4-DHEA.

Meanwhile, the recommended dosage from suppliers like Behemoth Labz is 75mg per day.

Regardless of the dosage amount, most agree that Post Cycle Therapy (PCT) is necessary after concluding your cycle with 4-DHEA.

Those that stick to dosage recommendations should receive noticeable results in the first cycle.

Then, the second cycle can allow you to gain even more impressive results as you consider increasing the dosage.

Those that stick within suggested dosage guidelines receive noteworthy weight and strength gains.

Results of 4 Andro Scientific Studies

There are varying opinions on the effectiveness of 4 Andro and other prohormones.

Nonetheless, it has not prevented 4 Andro from becoming popular supplementation for athletes and bodybuilders.

4-Androsterone (4-DHEA) may also increase power/strength and recovery time.

Research indicates these benefits become a reality after the anabolic agent gets converted into testosterone (2-step testosterone conversion).5

4 Andro is different from 1 Andro because it’s not a dry bulking agent.

Rather, 4 Andro produces lean muscle gains by focusing on testosterone conversion while being paired with other supplements (or, creating a weight stack).6

The overall safety and effectiveness of 4-Androsterone (4-DHEA) for human consumption remains questionable.

Unfortunately, there is only limited data to support the use of 4 Andro until more clinical research is dedicated to the compound.

4 Andro Reviews

There are plenty of personal testimonials that support the use of 4 Andro, despite a lack of clinical support.

For example, one review noted impressive first cycle results of an added 15lbs. of lean muscle.

The user also cited improvements in overall strength, power, energy, and recovery time.

Furthermore, 4-Androsterone was very successful when “stacked” with other supplements like RAD 140.

Alan Martinez, a verified owner of Behemoth Labz 4 Andro, felt “improvements all around” including shedding 5% of his body fat composition.

Meanwhile, another satisfied customer of 4 Andro was pleased with the “safe and secure” checkout process that also included fast delivery.

Lastly, check out what this guy had to say about 4Andro in his Youtube video: 

4 Andro Side Effects

Whenever people begin a new weight stack they are understandably concerned about any serious side effects.

4-Androsterone (4-DHEA) is a prohormone, after all, and some worry about side effects similar to other performance-enhancing drugs.

However, many consider 4-DHEA as one of the safest prohormones available on the market (especially because it’s still legal to purchase).

Thus, most note that so long as you stick to recommended dosage and cycle guidelines, you will not experience any serious side effects.

Be that as it may, users of 4-DHEA should also consider Post Cycle Therapy (PCT) to make sure they cycle off the substance correctly.

4-Androsterone is not recommended for those that are pregnant or breastfeeding.

Moreover, those that suffer from serious health problems or take prescribed medication should consult with a doctor before considering prohormone supplements like 4 Andro.

Let’s review some of the more serious side effects potentially linked to 4-DHEA:

Acne & Hair Loss

Unfortunately, some that use 4-DHEA note hygiene issues such as acne breakouts or hair loss.

Acne may appear on the face and body since testosterone levels are increased.

If the symptoms become unbearable, you may want to consider discontinuing use.


Gynecomastia is an unfortunate condition where men develop enlarged breasts.

It’s a common side effect of performance-enhancing drugs like synthetic anabolic steroids.

Fortunately, 4-Androsterone remains legal and is, therefore, a safer alternative to more powerful muscle growth stimulants like steroids.

Nonetheless, the possibility of developing gynecomastia remains as do other issues related to increased levels of estrogen in men.

High Blood Pressure

Supplementation for muscle growth and fat loss can increase blood pressure.

Thus, it’s important to monitor daily levels to make sure your blood pressure is not getting too high.

Often, 4-DHEA and other prohormones can increase levels which is detrimental if you already suffer from high blood pressure.

Since 4-Androsterone may worsen heart disease in some patients, we suggest consulting a licensed physician before starting the prohormone.

Liver Disease

There are varying accounts of what 4-Androsterone does to the liver.

For example, 4 Andro supplements (like the one available from Behemoth Labz) are marketed as non-toxic to the liver.

However, other sources indicate that 4-Androsterone may be harmful to the liver, especially when consumption is higher than the suggested daily dosage recommendations.

Thus, those with liver problems should not consider taking 4-DHEA.

Lastly, it’s also important to monitor alcohol consumption while on a cycle that includes 4-DHEA because of potential liver toxicity.

Stacking 4 Andro with RAD 140

4-andro and rad-140 stack

4 Andro is traditionally “stacked” with other muscle growth and fat-burning supplements.

For example, one of the most popular supplements to pair 4 Andro with is RAD 140

You’ll find plenty of reviews on forums like Reddit that discuss the power of this stack, here’s just one of them:

4 andro stack with rad 140 review

RAD 140 Testolone is one of the most powerful Selective Androgen Receptor Modulators (SARMs).

Today, SARMs are common in building weight stacks for gaining lean muscle and improving strength.

Thus, bodybuilders prefer to stack RAD 140 with 4-Androsterone and other complementary supplements for muscle mass.

RAD 140 Testolone is popular because, like 4 DHEA, it’s not known for producing extreme side effects compared to anabolic steroids.

Moreover, clinical support suggests that RAD 140 is more effective compared to other SARMs (like LGD-4033 and MK-2866 Ostarine).

Stacking 4 Andro with 1 Andro

4-andro and 1-andro stack

There are two types of Androsterone that affect the body in different ways.

For starters, 1 Andro does not convert to DHT or Estrogen, unlike 4 Andro.

Thus, 1 Andro is far more anabolic and produces more mass along with proper exercise and diet.

Additionally, 1 Andro may produce less serious side effects compared to its cousin.

Regardless, the two prohormones are often paired together to build an effective weight stack for muscle growth.

You may also want to consider stacking Androsterone with other SARMs or muscle mass and strength supplements like:

  • S-23
  • YK-11

Where to Purchase 4 Andro

4 Andro is available from reputable suppliers such as BehemothLabz.com.

The prohormone is available in either liquid form, or capsules, either of which will work the same.

The affordable muscle growth supplement includes a 60-day money-back guarantee.

Additionally, Behemoth Labz offers a 100% secure checkout experience as well as free shipping on orders over $100.

For years, athletes and bodybuilders have been seeking a safer alternative to performance-enhancing drugs.

In the past, substances like synthetic anabolic steroids have tarnished the reputations of sports and athletes seeking to gain an edge.

Furthermore, it has contributed to some nasty and dangerous side effects.

However, prohormones like 4-DHEA seek to help users gain lean muscle and burn fat without the horrible side effects.

While there is limited clinical research to support the use of 4-Androsterone (4-DHEA), personal testimonies state otherwise.

4 Andro is an effective muscle growth and strength supplement for users that stick to recommended dosage and cycle guidelines.

It’s especially powerful when combined with other SARMs and supplements to create a weight stack.
