Our bodies go through a range of changes as we age. Over time, we can become more susceptible to chronic illnesses, experience a reduction in hormones (including human growth hormone), and develop weaker immune systems. These changes can impair our ability to maintain our existing muscle mass and reduce our ability to heal from injuries, including the micro-tears of resistance training that help make us stronger. This can make it harder to maintain a healthy body composition as we get older, causing the loss of muscle and fat.
Ibutamoren, or MK-677, is an oral medication that combats muscle wasting by boosting the body’s natural ability to secrete human growth hormone (HGH).
Ibutamoren stimulates an increase in growth hormone levels by mimicking the action of the hormone ghrelin and binding to ghrelin receptors in the brain.
For individuals with a growth hormone deficiency, Ibutamoren MK-677 can help them rebalance their hormone levels and support healthy body function.
Ibutamoren interacts with ghrelin receptors in the brain to trigger the release of human growth hormone and insulin-like growth factor-1 (IGF-1).
This increase in human growth hormone levels can help to build and maintain muscle, support bone density and improve sleep. Key benefits can include:
Ibutamoren MK-677 has not been found to produce concerning side effects when dosed appropriately. Individuals who have Diabetes or are vulnerable to insulin sensitivity may be at risk of exacerbating symptoms when taking Ibutamoren MK-677.
While minor side effects of Ibutamoren MK-677 are rare, they most often occur as a result of improper dosing, leading to unnaturally high levels of HGH. These may include:
