What is MK-677?


MK-677, also known as ibutamoren, is a growth hormone secretagogue composed of all-natural peptides.  This compound is utilized to increase the production of growth hormone and enhance insulin-like growth factor 1 (IGF-1). It does so by mimicking the action of the hormone ghrelin by binding to one of the ghrelin receptors, which are found in the brain and control biological rhythms, cognition and appetite.

MK-677 increases the amount of growth hormone in the body by acting exactly like ghrelin and (GHSR), which in turn helps produce more growth hormone. The potential uses of MK-677 are limitless as increased levels of growth hormone are associated with increases in lean body mass, decreases in fat mass, increases in bone mineral density and activating genes critical to healing and recovery, all without any interference in the body's natural hormonal balance.

Benefits of MK-677:

Increased Bone Density:

Ibutamoren has been shown to increase calcium retention; this means that the elderly as well as those suffering from obesity or who may have mobility issues may find this compound beneficial as increased calcium retention from MK-677 will promote increases in bone mineral density.

Improved Sleep:

As Growth Hormone plays a crucial role in sleep quality, it is right to presume that MK-677 also assists with sleep quality since it stimulates production in Growth Hormone. Specifically, MK-677 has been clinically shown to increase the amount of time spent in stage 4 deep sleep by 50%, as well as REM sleep by 20%. This is critical as the more time spent in deep sleep, the more the body can recover and repair.

Increased Longevity:

MK-677 increases longevity by producing younger and more vibrant cells throughout your body. This benefit of MK-677 is specifically noticeable on your skin, as it’s the largest and most visible organ of your body. As growth hormone helps improve regeneration of your tissues and cells, MK-677 ends up making you look and feel younger.

Muscle Building:

MK-677 increases levels of both growth hormone and IGF-1, which are vital to building and maintaining lean muscle mass.  MK-677 has demonstrated the ability to significantly increase fat free mass in clinical studies.

Reduces Muscle Wasting:

MK-677 has been clinically proven to reverse the catabolism associated with a caloric restriction, making it a potent addition to any user's cutting protocol. 

Side Effects:

Side effects associated with MK-677 are minimal and may include increased appetite, joint stiffness, and lethargy as well as decreased insulin sensitivity with prolonged use.

The Bottom Line:

The GH boost from MK-677 is demonstrable but the hunger is real on this stuff; expect a constant feeling of "eh, I could eat" that literally never goes away.  For the hard gainer, this just might be the answer to your prayers, enabling you to finally pound down tons of quality calories.  In addition to increased appetite the most noticable effects will be the deeper sleep which will drastically increase recovery.  I highly recommend MK-677 at a maximum dose of 25 mg per day for any researcher's growth phase but the increase in hunger during a period of cutting may outweigh the benefits of increased GH levels for endomorphs.  For best results, stack MK-677 with a SARM that fits your goals and risk tolerance such as LGD-4033, Ostarine or RAD-140.

In short, the host of benefits and unique pathway through which MK-677 works make it a powerful addition to any researcher's arsenal.
