That is correct. Ostarine will help your muscles recover faster. Ostarine is also a very anti-catabolic compound so it will prevent muscle loss during periods of high stress (like during a cut where your calories are low and you are doing a lot of cardio).
The recommended dosage of ostarine is 25mg/day. If you order your ostarine from sarms1.com, each vial will last you 60 days at the recommended dosage.
