S-4 (Andarine) Protocol Guide

S-4 (Andarine) is one of the earlier SARMs developed, studied for fat loss and lean mass retention. Research shows a favorable effect on body composition with moderate anabolic activity. A notable research finding is dose-dependent visual side effects (yellow tint to vision, difficulty with night vision) believed to be related to binding to retinal receptors. These effects are temporary and resolve upon discontinuation. Capsule Content 25mg per capsule (25,000mcg per capsule) Route of Administration Oral (capsule)
