NUTROBAL (MK-677)Nutrobal or MK-677 (also known as Ibutamoren) promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1).Nutrobal increases growth hormone levels, by mimicking the action of the hormone ghrelin, and binding to one of the ghrelin receptors in the brain. Activated GHSR stimulates growth hormone release from the brain.BENEFITS OF USING NUTROBAL MK-6771. Helps Build Muscle - Nutrobal is frequently used as an anabolic substance, to increase lean body mass i.e. create bigger muscles. It is orally active and can be taken once a day. These are all benefits compared with other growth hormone stimulators.2. Reduces Muscle Wasting - In food-deprived healthy volunteers, Nutrobal reversed diet-induced protein loss, that could cause muscle wasting.3. Increases Bone Density - Growth hormone (GH) increases bone turnover and eventually bone density. However, because of the increased turnover in subjects treated with growth hormone, bone density can initially decrease before increasing. Basically, it takes time (> 1 year) to see the bone density increase.4. Improves Sleep - A study showed that in both younger and elderly subjects, Nutrobal 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, across various online forums.5. Combats Aging and may Increase Longevity - Growth Hormone (GH) secretion and muscle mass both decline from mid-puberty throughout life. In a study in the elderly, daily intake of Nutrobal increased GH and IGF-1 levels to those of healthy young adults without serious adverse effects. IGF-1 is known to have beneficial effects on longevity. In another study, Nutrobal rejuvenated the growth hormone profile in obese subjects. 6. May have Nootropic Effects - Some people use Nutrobal as a nootropic because it acts on the ghrelin receptor, which has nootropic effects. You can read more about these effects in the post on ghrelin. Science is, however, yet to study if and how ibutamoren affects cognitive performance. Two indirect mechanisms by which Nutrobal can improve brain function:* Nutrobal increases IGF-1, which is known to improve memory and learning.* Nutrobal also increases REM sleep duration and sleep quality. And we know that sleep is essential for good cognitive function. A study questioned the association of low IGF-1 and Alzheimer’s disease, and whether Nutrobal could be of help. However, in this study, Nutrobal was ineffective at slowing the progression of Alzheimer’s in humans.7. Beneficial for those with Growth Hormone Deficiency - Nutrobal can increase growth hormone, IGF-1, and IGFBP-3 levels in children with growth hormone deficiency. Furthermore, these effects are achieved without changing the concentrations of prolactin, glucose, triiodothyronine (T3), thyroxine (T4), thyrotropin,  cortisol or insulin. In severely GH-deficient men, ibutamoren increased IGF-1 and growth hormone, with no significant changes in cortisol, PRL, and thyroid hormone levels. However, insulin and glucose were increased.8. May Help with Wound Healing and Tissue Regeneration - Growth hormone increases tissue regeneration and wound healing, so Nutrobal may help with these. There are individual reports of Nutrobal being helpful, but scientific studies are lacking.9. May Help with Hangovers - This one is anecdotal, but people report curing hangovers with Nutrobal. Nutrobal MK-677 provides many benefits for fitness and bodybuilding particularly in improving one’s overall strength and performance. This SARM have been used by both Male and Female in many tests and have shown many positive results with virtually no side effects. Recommended Use:20 - 30mg before bed
