S-4 (commonly known as Andarine) attaches to the androgen receptor (AR) and sticks to it. Each time the AR interacts with testosterone, S-4 forces it to produce genes that exclusively benefit muscle and bone growth, generation selective anabolic activity. Due to this fastening and stimulation, more protein is produced which allows muscle building. S-4 also increases the amount of muscle mass produced by desensitizing the AR to the individual’s natural testosterone to influence a stronger effect. In other words, S4 can trigger muscle development with minus the same unwanted side effects.
