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-Androsterone is a wet, potent anabolic agent which changes into testosterone via a two-step transformation upon absorption. It is a nonmethylated prohormone, which means it has minimal effects or stress on the liver and organs of the user.

4-Andro works well as a stacker or used with other prohormones for bulking.  At 700 to 1,000 mg, you get the most awesome result when used in one compound cycle. As a part of a stack, 4-Andro’s sweet spot doses are between 300 to 500 mg.

How Does 4-Androsterone Work?

After being consumed, 4-Andro enters your bloodstream and converts into testosterone. The compound will start to have a noticeably high anabolic behavior, resulting to size and strength increases while enhancing your sex drive – giving you that incredible “Alpha Male Ecstasy.”

Benefits of 4-Andro

4-Androsterone targets the development of muscle gains specifically, around 8-12 pounds of lean muscle mass within 4 to 6 weeks of running the prohormone. Take note that this effect will be more evident with the right diet and workout.

In addition, expect to have these results:

  • Better power and strength
  • Improved cutting
  • Faster recovery time
  • Enhanced libido

Proper Dosing of 4-Andro

  • For beginners: run 4-Androsterone for 4 to 6 weeks at 300-500 mg.
  • For veteran users: run 4-Androsterone for 6 to 8 weeks at 300-750 mg.

Possible Side Effects (And How To Avoid Them)

4-Andro has little to no side effects. You may experience a minor estrogen conversion, muscle cramps, high blood pressure, aggression and in some cases gynecomastia (gyno).

An estrogen blocker is necessary to decrease estrogen conversion and avoid gyno as well as other estrogen connected side effects. These effects can be reduced or totally prevented with the right maintenance supplement.

Does 4-Androsterone Require On Cycle Support and PCT?

Yes, you need on cycle support when taking 4-Andro as it can affect your blood pressure. This is also essential for stimulating healthy blood pressure levels.

Likewise, post cycle therapy (PCT) is a vital part of the cycle as it will fundamentally help you retain the results while aiding your body in recovering its regular hormonal balance.

Stacking 4-Andro for Experienced Users

You may stack it with almost any compound or natural anabolic without worrying about any unwanted side effects, but it’s most ideally paired with 1-Andro and Epi-Andro (dry compounds) as these does an excellent job in minimizing or avoiding extra water retention.
