No, it isn’t a steroid. Steroids are a type of drug that has a similar effect as testosterone. If used for a medical concern, they are legal. However, they are considered to be illegal if used for anabolic muscle growth in athletic competitions, etc. TestRX doesn’t contain synthetic hormones in its’ formula. Using TestRX will cause your body to increase its testosterone level by itself because TestRX consists of minerals, vitamins, and amino acids.
