S23‎ (30ml

S23 is one of the most potent SARMs available, known for its high affinity with androgen receptors. It is distinguished by its ability to significantly increase muscle mass, strength, and bone mineral density. S23 also promotes notable fat loss, offering a “drier look” compared to RAD-140, partly due to its effect on body temperature and increased sweating. However, its use can lead to various side effects, including hair loss and disruption of the lipid profile, with notable adverse effects on blood lipids. It is also associated with increased aggression and may cause muscle cramps, so it is recommended to increase water and electrolyte intake to mitigate these effects.

Unlike other SARMs, S23 does not convert to estrogen, reducing the risk of gynecomastia. Its use has been studied as a male contraceptive, though it requires combination with estradiol benzoate injections to achieve a 100% infertility rate during administration. Compared to S4, S23 is considered more powerful, without the visual effects associated with S4.
