Ostarine, also known as MK-2866, is a type of Selective Androgen Receptor Modulator (SARM). It was initially developed to prevent and treat muscle wasting and osteoporosis. Unlike anabolic steroids, SARMs are designed to selectively target muscle and bone tissues, thereby reducing the likelihood of side effects associated with steroid use.

Ostarine works by binding to androgen receptors in the body, which then stimulates muscle growth and bone density without significantly affecting other organs. This selective action makes it a popular choice among bodybuilders and athletes for:

Muscle Mass Increase: Helps in increasing lean muscle mass by mimicking the action of testosterone.

Fat Loss: Assists in fat burning by increasing basal metabolic rate.

Injury Prevention and Recovery: Promotes faster recovery from bone and muscle injuries.

Strength Gains: Enhances strength, making workouts more effective.

Usage:

Ostarine is typically used in cycles, similar to anabolic steroids, but with a perceived lower risk of side effects. Dosage and cycle length can vary, often ranging from 10mg to 30mg per day for 4-8 weeks.
