4-Andro, also known as 4-Androstenedione, is a prohormone that converts into testosterone in the body. The question of whether its use leads to the suppression of natural testosterone production is a common concern. The suppression effect stems from the body sensing an elevated androgen level, signaling a reduced need for endogenous testosterone synthesis.
Understanding the impact of exogenous hormone use on the body’s natural hormonal balance is crucial for individuals considering such substances. The degree and duration of any potential shutdown can vary depending on dosage, duration of use, and individual physiology. Evaluating potential risks and benefits is necessary before introduction of prohormones into an individual’s routine.
