What is S4?
To start, let’s describe what a SARM does. There are three type of chemicals that act on the androgen receptor (AR). One is the an AR antagonist, which is a chemical that binds to the receptor to prevent it from activating. The second is an AR agonist, which binds to the receptor and detaches, then binds again, over and over. An example of an AR agonist is testosterone, each time the AR is bonded with testosterone, a signal is sent out to activate a particular set of genes. The more testosterone that is in the system, the more AR binding will occur. The third is an AR modulator, or basically a molecule that attaches to an AR and changes its structure to react however it wants.

How S4 Works
A SARM such as S-4 is a good example. S-4 attaches to the 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. In other words, 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.
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.
S-4 belongs to a class of chemicals known as SARMS or selective androgen receptor modulators. Like typical androgens, SARMS bind to the androgen receptor however SARMS create selective anabolic activity.Compared to testosterone and other anabolic steroids and pro hormones, the advantage of SARMS such as S-4 is that they do not have androgenic activity in non-skeletal-muscle tissues.
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.
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 eyesight.
For Cutting (best use of S4)
Andarine’s properties are very alike with steroids Anavar and Winstrol, the only difference is that S4 can better provide lean muscle gains. In fact, there have been many cases of bodybuilders gaining up to 3 pounds of lean muscle while on a caloric deficit! S4 displays the same binding resemblance to AR, hence presenting similar fat burning effects. S4 can also minimize LPL (lipoprotein lipase) – an enzyme that causes lipid accumulation and plays a role in storing adipose tissue (excess body fat). The AR oxidizes this adipose tissue and uses it as its preferred energy source, allowing the body to decrease excess fat at an amazing rate.
It also improves vascularity for that “aesthetic” chiseled look with minimal to no water retention. Unlike steroids, it won’t affect your joints but reinforce muscle mass and power instead. You can also say goodbye to painful pumps.
Recommended Dosage: 50 mg for 6-8 weeks.
*Take 2 days off when taking S4 (repeat the cycle after the 2 day break) to avoid vision side effects.
Use S4 with a more anabolic SARM such as Ostarine for better recomp results as you’re aiming to gain muscle while losing fat. Recommended intake is 50-75 mg for 4 to 8 weeks.
S-4 isn’t the sarm that comes to mind when we think “BULKING”, but it’s properties in muscle gain shouldn’t be overlooked. During the holiday season, many people take advantage of the excess food and snacks available and jump on some well known bulking SARMs such as LGD 4033 or RAD 140. While there isn’t an enormous 15 lb leap in muscle like these “bulk specific” products, S-4 can provide relatively large muscle gains and utilize these excess calories to provide an extra 8-10 lbs in muscle while also keeping the body relatively lean. This steady increase in muscle mass can limit the amount of work one needs to do for a leaner summer body.
