Trying to burn fat without losing muscle? Ostarine (MK-2866) may be the key to mastering the body recomposition game.
Body recomposition refers to the process of losing fat and gaining or preserving lean muscle at the same time. It’s the ideal outcome for many people—but physiologically, it’s tough to pull off. When you’re in a calorie deficit to shed fat, the body often breaks down muscle for energy, especially if training or nutrition isn’t perfectly dialed in. That’s where compounds like Ostarine come in — helping your body stay in a muscle-preserving state, even while burning fat. How Ostarine Works: Targeted Anabolism Without Estrogenic Side Effects Ostarine is a Selective Androgen Receptor Modulator (SARM), meaning it binds specifically to androgen receptors in muscle and bone tissue — without activating those in reproductive tissues. That selectivity means:
While other performance enhancers often focus on pure mass gain, Ostarine excels at maintaining what you already have. That’s crucial when you’re trying to lose weight but don’t want to sacrifice strength or muscle tone. Ostarine helps:
While results will always depend on training and diet, Ostarine works best when used strategically:
Ostarine is considered one of the safest SARMs for women, with most female users responding well to 5–10 mg/day. It provides anabolic support without triggering androgenic side effects like hair growth or deepening voice — especially at lower doses. For men, 10–20 mg/day is common for recomp or lean muscle support.
To enhance results, Ostarine can be combined with:
Ostarine isn’t magic — but it’s a scientifically backed, targeted tool that helps shift the odds in your favor when trying to achieve the holy grail of fitness: fat loss with muscle preservation. With smart training, consistent diet, and a well-timed cycle, Ostarine could be the edge that makes your recomp journey not just possible — but enjoyable.
