S23

Mechanism of Action & Benefits:

S23, also known as a Selective Androgen Receptor Modulator (SARM), is a compound that has been investigated for its potential use as a male hormonal contraceptive and for other medical applications such as the treatment of muscle wasting diseases and osteoporosis. In the context of bodybuilding, S23 is used off-label for its anabolic effects.

Mechanism of Action

S23 functions by selectively binding to androgen receptors in the body, particularly in muscle and bone tissues. It has a high affinity for these receptors, with a Ki of 1.7 nM, indicating a strong binding capacity. By targeting these receptors, S23 mimics the activity of testosterone, leading to an increase in muscle mass and bone density while potentially having fewer side effects compared to traditional anabolic steroids.

In animal studies, S23 has shown a good ratio of anabolic to androgenic effects, meaning it promotes muscle growth without as many androgenic side effects (such as increased body hair or acne). Additionally, it has been observed to cause dose-dependent suppression of spermatogenesis, with spontaneous recovery after cessation of treatment.

Benefits in Bodybuilding

The benefits of S23 in a bodybuilding context include:

  • Increased Muscle Mass: S23 can lead to significant gains in lean muscle mass due to its anabolic effects.

  • Fat Loss: S23 may help reduce body fat, contributing to a more defined physique.

  • Enhanced Bone Health: By stimulating androgen receptors in bone tissue, S23 could potentially improve bone density.

  • Improved Endurance: Some users report better endurance and the ability to work out for longer periods, which can be beneficial for intense training sessions.

Side Effects & Interactions:

Side Effects

The side effects of S23 are not fully understood due to the lack of comprehensive clinical studies. However, based on available research and anecdotal reports, potential side effects may include:

  • Testosterone Suppression: S23 can suppress natural testosterone production, which may lead to side effects such as cognitive fog and low mood. This suppression can be so severe that some users may require post-cycle therapy to restore their testosterone levels.

  • Liver Stress: S23 has been reported to elevate markers indicating liver stress.

  • Increased Aggression: Some users have reported increased aggression while using S23.

  • Night Sweats: S23 may cause increased body temperature, leading to night sweats and potential dehydration.

  • Hair Loss: Some users have reported hair loss while using S23.

  • Other Androgenic Effects: Other potential androgenic effects include acne outbreaks and lowered cholesterol.

More serious potential side effects include liver damage, heart attack, and stroke.

Interactions

The potential interactions of S23 with other substances are not well-studied. However, it is suggested that S23 may interact with other medications. Therefore, it is crucial to consult a healthcare provider before starting S23, especially if you are taking other medications.

Usage Guidelines:

  • S23 is typically taken orally.

  • The dosage can vary depending on the individual's tolerance and experience level, but a common starting dose is 10-20mg per day.

  • The dose is often split into two doses per day to maintain stable blood levels.

  • It's recommended to start with a lower dose to assess tolerance and gradually increase if necessary and well-tolerated.

  • The total daily dose should not exceed 50mg.

  • S23 is typically used in cycles of 8-12 weeks, followed by a break of at least 4 weeks.
