MK-677 is also known as Ibutamoren, Ibutamoren Mesylate or Nutrobal.

The reason why MK-677 is so special is that it has the ability to stimulate growth hormone levels (GH) and Insulin-like growth factor (IGF-1).

Ibutamoren is a growth hormone secretagogue. A Growth hormone secretagogue (GHS) is a compound that acts as a secretagogue which will help promote growth hormone levels.

Growth hormone is needed for the body to perform optimally. It plays a crucial role in the development of muscles and tissue.

It’s a quite complicated process but what you should know is that Ibutamoren does not interfere with other biological processes such as natural hormone production. This means that you will experience a boost in GH levels without side effects such as testosterone suppression.

Promotes Muscle Growth

One of the primary benefits you will experience from MK-677 is increased muscle growth. Due to the fact that Nutrobal increases GH and IGF-1 levels you will be able to put on size much easier. This has been backed up by science, a lot of user experiences show us that Ibutamoren does have a positive effect on building muscle tissue.
