Andarine/ S4 Usage As a research chemical, S-4 belongs to a class of chemicals known as SARMS. 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.// S4 was designed for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.// As an orally active partial agonist for androgen receptors, S-4 is effective in not only maintaining lean body mass but actually increasing it.
Dosage A dosing protocol of 50-75mg for 4-8 weeks will give good recomp effects.

S4 Description

Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands. They are intended to have the same kind of effects as androgenic drugs like anabolic steroids but be much more selective in their action, allowing them to be used for many more clinical indications than the relatively limited legitimate uses that anabolic steroids are currently approved for.

S-4 is an experimental or investigation-stage proprietary SARM research chemical developed by GTx Inc for treatment of benign prostatic hypertrophy, muscle wasting, and osteoporosis. S-4 is considered a partial agonist of the androgen receptors in target tissue. S-4 has less pronounced  anabolic and androgenic compared to other SARMs. In trials treating BPH induced in animal models, S-4 reduced prostate weight as effectively as finasteride and without producing any reduction in muscle mass or other side effects common with androgen receptor binding compounds. Gao et al suggest that by binding to androgen receptors, S-4 prevents DHT from binding and activating, but bypasses the expected anti-androgenic effects that would occur from occupying androgen receptors due to the fact that S-4 itself is a partial agonist of androgen receptors. S-4 has also been shown to prevent bone loss, reduce body fat, and improve muscle strength and body composition in orchidectomized and ovariectomized rats.

S4 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.

S4 Application

1) Cutting(recommend S4): S4’s properties are very alike with steroids Winstrol and Anavar, the only difference is that S4 can better provide lean muscle gains. 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

Furthermore, Andarine also decreases fat while maintaining and even boosting muscle mass in a hypocaloric environment. 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.

2) Recomping: 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.

3) Lean Muscle and Strength Gains (sans bloating): The strength gains that Andarine produces are quick, lasting, maintained and very clean. S4 makes you feel good all over.

S4 Dosage

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.
