MS. Andarine Selective Androgen Receptor Modulators S4 401900-40-1 Muscle Building SARMs
Usage It is a potent and tissue-selective androgen receptor modulator (SARM).



S4 (Andarine) or Acetamidoxolutamide, is a SARM (Selective Androgen Receptor Modulator). S4 is said to be the most potent SARM which helps sustain lean muscle mass while stimulating fat elimination at the same time.


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 around 33% 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 SARM with maximum potential with a disintegration process of just 4 hours. It can decrease the size of the prostate if taken as recommended. It is administered orally.


It’s shown to be beneficial for muscle degeneration, osteoporosis and benign prostatic hypertrophy (with bicalutamide – a non-steroidal androgen antagonist) treatment. Aside from preserving lean body mass, S4 can also help improve it.


Aside from its muscle building advantages, S4 won’t cause liver damage, can prevent gynecomastia (enlarged breasts in men) and can help boost your overall health .




As said earlier, SARMS function by tying to the AR resulting to anabolic activity. Due to this fastening and stimulation, more protein is produced which allows muscle building. S4 can trigger muscle development in the same way as steroids, but minus the same unwanted side effects, the latter has on the prostate and other sexual organs.


How it’s used depends on what effects you’re looking after. Fat elimination or cutting is the most effective use for S4 Andarine.


Right Dosing.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.


Uses of Andarine



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. 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.
  • Recommended Dosage: 50 mg for 6-8 weeks.
For 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.
For 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.
  • Suggested dosage is 50mg.
