Ibutamoren (also known as ibutamoren mesylate or MK-677), promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1)

Ibutamoren increases levels, by mimicking the action of the hormone ghrelin , and binding to one of the ghrelin receptors in the brain ). Activated ghrelin receptors stimulates growth hormone release from the brain.

Benefits of increased GH and IGF-1 include:

. Increased bone turnover and eventually bone density
. Improved sleep quality and REM (rapid eye movement) sleep duration.
. Reduced Muscle Wasting
. Increased muscle mass
. Reduced fat mass
. Possible healing of tendons, joints and ligaments

Also included in the product is


Alpha-GPC is a cholinergic compound that is used for its cognitive-promoting properties, and to enhance power output in athletes. It appears to also support cellular membranes, and may aid in preventing cognitive decline.

Oral supplementation of alpha-GPC is of interest for nootropic purposes, as it appears to have cognitive-enhancing properties.

Athletes are at times interested in alpha-GPC due to its ability to enhance growth hormone production and to also enhance power output.

And also


Huperzine-A is a cognitive enhancer that inhibits an enzyme that degrades the learning neurotransmitter, acetylcholine; and so due to this, a relative increase occurs.

Acetylcholine is known as the learning neurotransmitter, and is involved in muscle contraction as well. Increasing levels of acetylcholine is routinely used as a technique amongst weight-lifters and those undertaking extensive studying (college and university students).

Bulking must!

For me, eating was the biggest barrier to my path. I never felt hungry or finished a healthy serving size. But after taking MK677 I’ve never felt hunger like it! (Which can be an issue when you’re not used to it or on a cut) and it’s at a point where I’ve found a balance between eating enough calories and the hunger feeling! On the growth side; eating the amount I have been recently hasn’t increased my fat percentage, in fact I feel bigger and leaner than ever, and I’m still progressing! Very happy with my purchase! But always do you’re own research into these things.


Very good and have seen major improvements

My father feels like he has more focus and energy

My father suffers from fibromyalgia and we tried MK677 as a Hail Mary. He claims it gives him more mental clarity and energy during the day, which is amazing.

This is great news Lee, hope your father continues to improve. Team-OHS
