Description
Ostarine (also known as MK-2866) was originally developed to treat diseases that cause muscle wasting. Today, its effects are so effective that it’s used not only for medical purposes but also by individuals looking to increase lean muscle mass and burn body fat quickly. Ostarine has no androgenic or masculinizing effects, making it safe for women to use.
Combined with MK-677 (Ibutamoren, L-163191), you get an additional boost in endogenous growth hormone production, as it is a potent growth hormone secretagogue—promoting a significant increase in the body’s own GH output. It works by mimicking the action of ghrelin, an endogenous hormone that stimulates natural GH release.
It has been shown to increase plasma levels of various hormones, including growth hormone and IGF-1, without affecting cortisol levels.
It does not alter testosterone, estrogen, or DHT levels. There are no androgenic side effects, and it does not cause hair loss. It does not aromatize.
It is not a methylated compound, meaning it does not cause liver toxicity—no liver protection is required.
