S4(10 gms)

**S4**, also known as **Andarine**, is a selective androgen receptor modulator (SARM) that is popular for its anabolic effects. Here are the primary uses and benefits associated with S4:

### Uses of S4 (Andarine)

1. **Muscle Growth**:
- **Increased Muscle Mass**: S4 is known to promote lean muscle mass gains, making it a popular choice among bodybuilders and athletes.
- **Muscle Preservation**: It helps preserve muscle mass during cutting cycles, preventing muscle loss when in a calorie deficit.

2. **Fat Loss**:
- **Enhanced Fat Oxidation**: S4 can help reduce body fat by increasing metabolism and promoting fat oxidation, leading to a leaner physique.
- **Visceral Fat Reduction**: It may specifically target and reduce visceral fat, which is the fat surrounding internal organs.

3. **Improved Strength and Endurance**:
- **Increased Strength**: Users often report significant improvements in strength, allowing for better performance in weightlifting and other strength-based activities.
- **Enhanced Endurance**: S4 can improve endurance, making it beneficial for athletes and those engaged in high-intensity training.

4. **Bone Health**:
- **Increased Bone Density**: S4 has been shown to improve bone mineral density, which can be beneficial for individuals with osteoporosis or those looking to strengthen their skeletal system.

5. **Potential Therapeutic Uses** (Under Research):
- **Muscle-Wasting Conditions**: S4 is being studied for its potential to treat muscle-wasting diseases, such as sarcopenia and cachexia.
- **Osteoporosis**: It may be useful in treating osteoporosis by promoting bone density and strength.

### Mechanism of Action

S4 works by selectively binding to androgen receptors in the body. This selective binding allows S4 to mimic the effects of testosterone in muscle and bone tissues while minimizing the undesirable side effects associated with anabolic steroids, such as prostate enlargement and hair loss.

### Administration

S4 is typically taken orally. The dosage and cycle length can vary, but common doses range from 25 to 50 mg per day, often taken in cycles of 6 to 8 weeks. Due to its short half-life, S4 is usually split into multiple doses throughout the day.

### Side Effects

While S4 is generally considered to have a favorable safety profile compared to anabolic steroids, potential side effects may include:

- **Vision Changes**: One of the most reported side effects of S4 is vision changes, such as a yellow tint to vision and difficulty adjusting to darkness. These effects are generally reversible upon discontinuation.
- **Hormonal Imbalance**: S4 can affect natural testosterone levels, potentially leading to hormonal imbalances. Post-cycle therapy (PCT) is often recommended after a cycle to help restore natural hormone levels.
- **Liver Toxicity**: There may be a risk of liver toxicity with prolonged use, although this risk is generally lower compared to anabolic steroids.

### Conclusion

S4 (Andarine) is a potent SARM known for its ability to promote muscle growth, fat loss, and improved performance. However, due to potential side effects and the need for further research, it is important to use S4 responsibly and consult with a healthcare professional before starting any cycle.
