Andarina (S4)

What is Andarine?

Andarine, also known as S4, is a Selective Androgen Receptor Modulator (SARM) developed by GTx Inc. It was originally researched for the treatment of muscle wasting, osteoporosis, and benign prostatic hypertrophy (BPH). S4 is known for providing lean muscle gains and fat loss, making it popular for cutting cycles.

⚙️ How It Works

Andarine binds selectively to androgen receptors in muscle and bone, stimulating anabolic activity while minimizing side effects related to other tissues (like the liver or prostate). Its moderate anabolic properties help preserve lean mass while encouraging fat reduction.
