S4 (Andarine): Overview, Benefits, and Usage
 
What is S4? S4, also known as Andarine, is a selective androgen receptor modulator (SARM) that was originally developed to treat conditions such as muscle wasting and osteoporosis. S4 is known for its ability to promote lean muscle growth, enhance fat loss, and improve overall body composition. Among SARMs, S4 is recognized for its strong anabolic effects, making it popular among bodybuilders and athletes during both cutting and recomposition cycles.
 
What Does S4 Do? S4 is effective in promoting several fitness and physique-related benefits:
Lean Muscle Gains: S4 is particularly effective at promoting lean muscle mass. While not as potent as some other SARMs in terms of bulking, it helps users achieve solid, lean gains with minimal water retention.
Fat Loss: Andarine is well-known for its fat-burning properties. It enhances the body's ability to oxidize fat, making it ideal for cutting cycles where the goal is to lose fat while preserving muscle mass.
Improved Vascularity: S4 can enhance vascularity and muscle hardness, giving users a more defined and "cut" appearance, which is especially desired during cutting phases or pre-competition.
Increased Strength: Users often experience noticeable increases in strength, which can improve workout performance and support muscle growth.
Minimal Water Retention: Unlike some other anabolic agents, S4 does not cause significant water retention, resulting in a drier, more aesthetic physique.
 
How and When to Take S4 S4 is typically taken orally, and its effects are optimized with proper dosing and cycle management.
Dosage: The typical dosage for S4 ranges from 25 to 50 mg per day. Some users may start at a lower dose of 25 mg per day to assess tolerance, gradually increasing to 50 mg per day for more pronounced effects.
Timing: S4 has a relatively short half-life of about 4-6 hours, so it is usually split into two doses taken throughout the day (e.g., morning and evening) to maintain stable blood levels.
Cycle Length: A typical S4 cycle lasts between 6 to 8 weeks. Due to the potential for side effects, it is advisable not to extend the cycle beyond this period without taking a break. Post-cycle therapy (PCT) may be necessary, especially after higher doses or longer cycles.
