S4 Andarine Basic Info

What is S4?

S4 is a form of SARM that attaches to the androgen receptor (AR) the same with regular androgens, the only variation is that S4 generates selective anabolic activity. S4 is a SARM with utmost androgenic effects as it has 1/3 of the strength of testosterone when attaching to AR.
Compared to anabolic steroids and prohormones, Andarine does not have androgenic activity in non-skeletal muscle tissues
S4 is a very effective SARM with a half-life of 4 hours. It can decrease the size of the prostate if taken as recommended. It is administered orally.

Right Dosing of S4 Andarine;

Recommended dose for cutting is 50 mg for 6-8 weeks. You should use it every day then take 2 days off for the duration. Taking S4 daily for the length of the cycle can lead to changes in vision.
S-4 (3 mg/kg/day) was also able to restore skeletal muscle (i.e., soleus muscle) and strength in castrated rats, important and applicable for the treatment of muscle wasting and male HRT.

A 120-day study comparing SARM S-4 and dihydrotestosterone (DHT) treatment in ovariectomized rats demonstrated that S-4 was able to maintain bone mass and bone strength to the levels of intact controls and exhibited greater efficacy than DHT.

Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects.
