MK-677 (often referred as Ibutamoren) promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1). Ibutamoren increases growth hormone levels by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors (GHSR) in the brain. Activated GHSR stimulates growth hormone release from the brain. Clinical studies describe only the effects MK-677 has on appetite and as expected, like ghrelin, MK-677 increases it. GHSR is found in brain regions that control appetite, pleasure, mood, biological rhythms, memory, and cognition. Therefore, we can expect that Ibutamoren may also affect these functions. It increases growth hormone levels with little or no increase in other hormones, such as Cortisol. Cortisol suppresses the immune system, reduces wound healing, and impairs learning and memory, and it’s usually not good to have this hormone elevated.

MK-677 benefits:

– Muscle-building

– Increased bone density

– Reduction in muscle wasting

– Improved sleep quality and well-being

– Anti-aging properties.

MK-677 may also be beneficial in treating Human Growth Hormone (HGH) deficiencies.

Helps Build Muscles: Bodybuilders use MK-677 as an anabolic substance, to increase lean body mass. It is orally active and can be taken once a day. MK-677 stimulates Human Growth Hormone (HGH) and IGF-1 (insulin-like growth factor) which each factor in significantly to maintaining lean body mass. It’s believed, that HGH (Human Growth Hormone) stimulates an increase in muscle strength and size, so the ability of MK-677 to increase Growth Hormone production makes it highly demanded on the market today. Research that has studied 60 year old men indicated that injections, which stimulate an increase in Growth Hormones led to increased strength in the thigh muscles. The results of MK-677 in muscle growth stimulating, depends on the person (on its exercise program and health conditions) and can be various.

Reduces Muscle Wasting: Recent studies have shown that MK-677 could alleviate muscle wasting that can be caused by a decline in protein within an individual’s diet. A group of healthy young adults was tested to determine if MK-677 could reverse protein catabolism and the results proved to be quite positive. As a result MK-677 is theorized to possibly be an effective treatment for people who suffer from catabolic conditions.

Increases Bone Density: Several research studies have indicated that long-term use of MK-677 can give a great result increasing bone mineral density. This effect of MK-677 can be beneficial for obese individuals, women with menopause and older adults. These categories of people can have health problems due to low bone mineral density and MK-677 has proven to be an effective treatment for many of them. In a study of 140 elderly adults (60 years and older), Ibutamoren had increased bone building, as measured by Osteocalcin, a marker of bone turnover in multiple studies. 150 post-menopausal women also took part in MK-677 study. The result was increased bone mineral density, which helps increase bone strength and prevent osteoporosis. People who want to increase bone density by using MK-677, must be ready to have the possibility of any long-term side effects. This is due to the fact that, increases in bone density typically can be felt only after one year of intake.

 Improves Sleep: HGH (Human Growth Hormone) is known for its ability to help improve sleep quality. It’s believed that, MK-677 can improve sleep quality since it stimulates production in Growth Hormone. Several studies showed that in both younger and elderly subjects, Ibutamoren improved sleep quality and REM (Rapid Eye Movement) sleep duration. Apart from scientific studies, there have been many reports of subjective improvements in sleep quality.

Anti-Aging and Increased Longevity Properties: As we already know HGH (Human Growth Hormone) usually begins a steady decline at a certain age. Aging people can increase Growth Hormone and IGF-1 levels by using MK-677. Aging people taking MK-677 can improve their overall hormone profiles as they give their declining Growth Hormone (GH) levels a boost. In a study with 80 elderly men and women, daily dose of Ibutamoren increased their GH and IGF-1 levels without serious side effects. Around 30 obese males increased their Growth Hormone (GH) profiles, in another MK-677 study. Thanks to the Growth Hormone higher concentration, bones become stronger, muscle tissue grows and more intensive recovery of the body at the cellular level is observed. In addition, Growth Hormone helps to stabilize the mental state and boost immunity.

May Have Nootropic Effects: It is believed that MK-677 can have the same effects on the brain that Ghrelin has. There are no studies that confirm MK-677’s direct nootropic effects on the human brain. Looking back at the previous section, we already know about a study that shows us promise that Ibutamoren has the ability to improve sleep quality by increasing REM sleep. Obtaining the proper amount of sleep each night is extremely important when trying to achieve an adequate cognitive function. MK-677 can improve cognitive function by assisting with the ability to get a good night’s rest. We know that sleep is essential for good cognitive function.

Beneficial in Treating Growth Hormone Deficiency: Children with growth hormone deficiency can increase their Growth Hormone, IGF-1 and IGFBP-3 levels using MK-677. Furthermore, these effects could be achieved without changing the concentrations of prolactin, glucose, triiodothyronine (T3), thyroxine (T4), thyrotropin, cortisol or insulin. In severely men with GH deficiency, Ibutamoren increased IGF-1 and growth hormone levels with no significant changes in cortisol, PRL and thyroid hormone levels. However, insulin and glucose were increased.

Mk-677 side effects: MK-677 has not many side effects to be concerned about. People with insulin sensitivity or who have Diabetes may be at risk when taking MK-677. Symptoms associated with these conditions could possibly be exacerbated by the use of MK-677. As with any other compound, correct dosage and usage of MK-677 is the key. In studies that looked at how MK-677 increases muscle mass, the dosage was the key. Side effects of Ibutamoren are usually the result of two things: improper dosage and extended use. Reported side effects of MK-677 are typically the result of unnaturally high levels of growth hormone in the body from taking too much too often, which include:

-Insulin resistance

-Increased appetite

-Lethargy

-Joint pain if you have previous medical conditions or elevated hormone levels

-Possible increase in prolactin levels, which can be controlled

If the dosage of MK-677 is correct, the side effects of MK-677 are minimal to none compared to the results you get from taking it properly.

Conclusion: MK-677 provides numerous health benefits for people with certain conditions. People with low bone density, who have trouble sleeping at night and with catabolic conditions can all benefit greatly from the use of MK 677. The ability of the MK-677 secretagogue to effectively secrete Growth Hormone and IGF-1 proves to be a useful compound for many people. Athletes taking MK-677 have the ability to build muscle mass, increase strength and endurance.
