S23 works by selectively binding to androgen receptors in the muscle and bone tissues, which results in an anabolic effect—essentially promoting muscle growth. The advantage of S23, when compared to traditional steroids, is its selectivity. It specifically targets muscles and bones, which helps minimize the risk of unwanted side effects that often occur with steroids, as those typically affect multiple areas of the body.
S23 is considered one of the strongest SARMs available, and it’s often compared to steroids like Winstrol or Anavar for its muscle-building potential. It stimulates protein synthesis in muscle tissue, which leads to an increase in lean muscle mass. Many bodybuilders report that the muscle gains they achieve with S23 are more defined and hard without the typical bloating or water retention often associated with traditional steroids.
Another notable benefit of S23 is its ability to promote fat burning while maintaining muscle mass. This makes it particularly useful during cutting phases, as it helps accelerate the metabolism and encourages the body to utilize stored fat for energy. The result is a leaner, more sculpted physique. This makes S23 a popular choice for body recomposition, where the goal is to build muscle and lose fat simultaneously.
S23 is also frequently referred to as a “hardener” due to its ability to give muscles a more grainy, chiseled appearance—similar to what’s seen with DHT-derived steroids like Masteron. This effect is particularly desirable for bodybuilders preparing for competitions or photoshoots where muscle definition is a key focus.
However, while S23 can be highly effective for muscle growth and fat loss, there are some potential downsides to consider.
First, testosterone suppression is a significant concern. S23 can suppress natural testosterone production, so if you use it for an extended period, you may need a post-cycle therapy (PCT) to restore hormone balance. Without PCT, you may experience symptoms like low energy, low libido, or even muscle loss after discontinuing its use.
Additionally, while S23 is generally less liver-toxic than steroids, it can still have an impact on liver function, especially with long-term use. Monitoring liver health is important if using S23 over a prolonged period.
In summary, S23 can be a powerful tool for building lean muscle and promoting fat loss, but it’s essential to be aware of the potential side effects, particularly related to testosterone suppression and liver health. Careful planning, including the use of PCT, is recommended when incorporating S23 into a regimen.
