S-23 is a selective androgen receptor modulator (SARM) of the 6th generation. This non-steroidal drug has high bioavailability (over 96%) and binds only to androgen receptors in bones and muscles. The goal of the drug is to treat muscle wasting and osteoporosis.

Athletes use the drug to increase muscle mass and strengthening bone tissue while reducing fat mass. S-23 does not make water retention and allows achieving high muscle definition.

The half-life of the drug is 12 hours. The peak level of the drug in the blood is 4 hours after intake.

S-23 properties:

  • Increases lean muscle mass.
  • Reduces the amount of fat.
  • Increases bone strength.
  • Increases power and toughness.
  • Improves muscle definition.

The drug’s ability to burn fat depends on the dosage: the higher the dosage, the faster and more fat is burned.

Women get the following benefits from taking the drug: libido increases without risks associated with testosterone; fat tissue decreases, muscle mass is maintained; and bone density improves. A side effect of the drug is its ability to suppress the production of LH and FSH that leads to its contraceptive effects and lower testosterone levels, but this side effect is temporary. However, taking high doses of S-23 can have the opposite effect and actually cause sperm production rather than its inhibition. It is worth noting that S-23 does not increase the prostate size, but even reduces it.

Side effects can also include increased aggression at high doses.

All side effects are temporary and disappear after discontinuation of taking the drug. Post-cyclic therapy (PCT) should be used to quickly restore testosterone levels.

The optimal dosage of the drug for increasing muscle mass is 10-30 mg per day. Given the drug half-life, the drug intake should be divided into 2 times a day. The cycle of the drug intake is 8-12 weeks.

S-23 is one of the most powerful SARMs for increasing muscle mass, with small temporary side effects, the result of which is comparable to those from using potent anabolic androgenic steroids without androgenic side effects.
