4-Andro - Supplement Shop


4-Andro is a common name for the prohormone 3β-Hydroxy-4-androsten-17-one.  This compound is also referred to as: 4-androstene-3b-ol-17-one, 4-dehydroepiandrosterone, or 4-DHEA.

What is 4-Andro?

4-Andro is a non-methylated prohormone.  It is a precursor to the male hormone Testosterone, the king hormone and necessary compound for any cycle.  4-androsterone is taken orally, it is absorbed through the stomach into the blood stream, then processed in the liver.  In the liver, the inactive prohormone undergoes two transformations carried out by enzymes.  This process converts 4-andro to the active muscle building hormone Testosterone. 


How Do I Take It?

The recommended dosage of four andro is between 50-100mg per day for a cycle lasting four to six weeks, followed by a break or "post-cycle therapy" period. It can be taken orally in pill form or as a liquid solution, with some users preferring to split their daily dose into two smaller doses taken morning and evening. As with any supplement, be sure to follow the recommended dosage and cycle length for safe use.

How Does It Work?

The body converts four andro into testosterone, leading to increased muscle mass and strength. It may also improve recovery time and enhance athletic performance. However, it is important to note that the effects of prohormones can vary widely between individuals and may not be as significant as those achieved through traditional methods such as diet and exercise.

Potential Side Effects

As with any supplement or medication, there are potential side effects to be aware of with four andro. These can include

  • Hair loss
  • Acne
  • Increased aggression
  • Changes in cholesterol levels

Before starting any supplement regimen, it is always best to consult with a healthcare professional to ensure the safe use

Cycling And PCT

Those who are interested in using prohormones must know the proper way of taking them. Pro hormones typically come with a 30-day or 60-day cycle and when running these types of supplements you will see results around week three so for the best effect one should continue until their bottle has been gone through completely (at least 2 weeks).

With most bottles lasting thirty days there isn't much motivation to go beyond this duration unless someone wants bigger muscles faster; however, if somebody does need more than 1 month's worth then an additional support item called "cycle support" may help assure adequate liver function as well as estrogen levels remain under control.

The post-cycle treatment (PCT) is a crucial part of your anabolic steroid cycle. It helps restore testosterone levels and Homeostasis after they've been suppressed, as well as returning your body to its normal state--this can be done through supplements like Turkesterone or Laxogenin which help maintain muscle gain while on the medications along with natural muscle builders such epicatechin found in certain fruits like apples.
