IGF-1 For Endurance?

Hey bro's

I've heard that some pro cyclists or endurance athletes use HGH so I was wondering if IGF-1 could be a good choice for me and provide me with any worthwhile benefits. It would definatley be a lot safer than some of the alternatives.

Any information on the effects of IGF-1 on endurance or red blood cell count would be appreciated!

i did during boxing routine.......had more energy maybe from having slept better......but the pumps in my calvves woould get so intense my cardio workouts had to be cut short
