IGF-1

IGF or Insulin Like Growth Factor is used by bodybuilders for a number of different reasons:

Firstly it helps reduce overall bodyfat whilst also simultaneously increasing muscle mass and strength. It does this by increasing nitrogen retention which inturn leads to an increase in protein synthesis.

There is some speculation on whether or not IGF leads to an increase in red blood cell production and thus also leading to the same effects of EPOGEN.

Use of IGF-1 leads to a decrease in insulin production within the body, this however does lead to an increase in insulin sensitivity

Dose
