SARMS-ANDARINE® 25 mg (S4)

SARMS-ANDARINE® 25 mg, also known as S4 (Andarine), is a selective androgen receptor modulator (SARM) known for its effects on lean muscle preservation, fat loss, and overall body recomposition. It is designed to selectively bind to androgen receptors in muscle and bone tissue, promoting anabolic activity with reduced systemic androgenic effects compared to traditional steroids.

How It Works

Andarine works by binding to androgen receptors in skeletal muscle and bone, stimulating anabolic processes that support muscle growth and reduce muscle breakdown. This mechanism may help improve strength, preserve lean mass during calorie deficits, and enhance fat metabolism, making it commonly associated with cutting cycles and physique refinement.

Dosage Overview

Typical dosing ranges from 25–50 mg per day, usually split into 1–2 doses. Beginners often start at 25 mg daily to assess tolerance, while more experienced users may increase up to 50 mg per day depending on goals. Cycle lengths generally range from 6–8 weeks, followed by a recovery period. Use with food may help with tolerance and absorption.

Potential Benefits

Andarine is associated with increased lean muscle retention, improved fat loss, enhanced vascularity, and greater strength output. It is often used during cutting phases to maintain muscle while reducing body fat, contributing to a more defined and “dry” physique. It may also support bone health through androgen receptor activity in bone tissue.

Side Effects and Considerations

Possible side effects include temporary vision disturbances (such as yellow tint or difficulty adapting to low light), headaches, and dose-dependent testosterone suppression. These effects are typically reversible after discontinuation. Due to potential hormonal suppression, post-cycle recovery strategies are commonly considered in user protocols.
