S4 Andarine
Andarine powder is the raw form of the selective androgen receptor modulator (SARM) known as Andarine or S-4. This powder can be used in research settings to study the effects of SARMs on muscle growth, bone density, and other physiological processes.
Andarine, also known as S-4, is a type of Selective Androgen Receptor Modulator (SARM). SARMs are a class of therapeutic compounds with properties similar to anabolic agents but with reduced androgenic (producing male characteristics) properties. They are designed to selectively target and activate androgen receptors in specific tissues like muscles and bones rather than affecting the entire body like traditional anabolic steroids.
Mechanism of Action:
Selective Binding: Andarine binds selectively to androgen receptors in muscle and bone tissues, stimulating anabolic activity (muscle growth) and anti-resorptive activity (preventing bone loss).
Reduced Side Effects: Due to its selective nature, it aims to minimize the side effects commonly associated with anabolic steroids, like liver damage, hair loss, and changes in cholesterol levels.
Research Applications:
- Muscle Wasting: Studied for its potential to combat muscle wasting conditions.
- Osteoporosis: Investigated for its ability to improve bone density and strength.
- Benign Prostatic Hypertrophy: Examined for its potential benefits in reducing prostate size.
Andarine Benefits
In the fitness community and on various online forums, S4 is touted as a muscle-building supplement that reduces weight and promotes muscle growth and repair.
- Muscle Growth and Strength: Andarine can increase lean muscle mass and strength, which makes it attractive to bodybuilders and athletes.
- Fat Loss: It has shown the potential to promote fat loss while preserving muscle mass.
- Bone Health: Andarine may improve bone density, offering potential benefits for individuals with osteoporosis.

Key Benefits of Andarine S4 for Sale:
- 99%+ Purity Guaranteed: Our Andarine S4 is lab-tested to ensure high purity, providing a safe and effective product for muscle growth and fat loss.
- Muscle Growth: Andarine S4 promotes lean muscle gains, making it ideal for bodybuilders and athletes focused on enhancing strength and performance.
- Fat Loss: Andarine S4 helps reduce body fat while preserving muscle mass, making it an excellent choice for cutting cycles.
- Bone Health: Andarine S4 has positive effects on bone density, enhancing skeletal strength alongside muscle development.

Andarine Stack
Andarine is comparatively weaker than popular SARMs, so it is commonly stacked with other SARMs, such as Testolone (RAD140), Ligandrol, and Ostarine.
- For cutting, it is advised that it (25 mg) be stacked with S4 (20 mg, a non-SARM, peroxisome proliferator-activated receptor-delta agonist) daily for 12 weeks.
- For strength, it is suggested that S4 (50 mg) be stacked with Ligandrol (10 mg) daily for 2 to 3 weeks.
- For bulking, it is recommended that S4 (50 mg) be stacked with Testolone (10 mg) daily for 8 to 12 weeks.
- For body recomposition (i.e., simultaneously losing fat and gaining muscle), it is recommended that S4 (50 mg) be stacked with both Ostarine (25 mg) and Cardarine (20 mg) daily for 9 to 12 weeks.
Andarine Dosage
In research contexts, dosages vary widely but generally between 25 mg and 50 mg daily. These dosages are not standardized and should be determined based on specific research protocols.
In research studies, Andarine powder can be mixed with a liquid to form a solution for oral administration.
Andarine Side Effects
- Vision Disturbances: Users have reported side effects such as a yellow tint to vision and difficulty adjusting to changes in light.
- Hormonal Imbalance: Andarine can suppress natural testosterone production, potentially leading to hormonal imbalances.
- Other Effects: Possible liver toxicity and other systemic effects, although these are less common compared to traditional anabolic steroids.
Andarine vs Ostarine
Andarine (S-4) and Ostarine (MK-2866) are both selective androgen receptor modulators (SARMs) developed to offer the benefits of anabolic steroids without many of the associated side effects. However, they have different properties and potential applications. Here’s a comparison of the two:
