WHAT IS MK677?
MK-677, also known as Ibutamoren, is one of the compounds commonly referred to as SARM. It is very popular among athletes and bodybuilders.
Etomol is actually a selective agonist of growth hormone secretagogues. It is an orally active compound that stimulates the secretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1).
Other growth hormone secretagogues are mainly peptides, such as GHRP-2, GHRP-6, hexosin and so on. Most of these substances increase cortisol levels. This is not the case with MK 677, which is one of the reasons that makes it a unique compound.
WHAT'S THE FUNCTION OF THE MK677?
1. Promote muscle growth
It promotes muscle growth and strength by increasing lean body mass (larger muscle, increased muscle mass, preventing muscle loss during weight loss, etc.) without increasing fat mass.
2. Improve muscle atrophy
It can resist muscle atrophy commonly seen in elderly or temporarily incapacitated people (such as hip fractures).
3. Improve bone density
It can increase bone density and renewal (by increasing osteocalcin levels).
4. Improve the proper amount of sleep and increase the length of sleep
Elevated levels of certain hormones (especially growth hormone and prolactin) seem to increase the duration of stage 4 sleep (the deepest sleep cycle) and rapid eye movements (REM)
It mainly fights cellular senescence by compensating for the decline in growth hormone levels.
It also has potential nootropic effects.
6. Promote wound healing and enhance exercise endurance
7. Promote increased fat breakdown
8. Reduce nitrogenous waste in the body.
9. Reduce the level of low-density lipoprotein cholesterol in the blood.
These potential effects are the result of Ibutamoren’s main role in directly increasing the level of IGF-1 in the circulation, IGF-1 is a peptide hormone responsible for promoting protein synthesis and promoting overall tissue growth.
