Has anyone else noticed an extreme decrease in cardiovascular endurance with IGF use. I am using IGF at 50mcgs per day 5 on 2 off for 2 weeks so far. I am also in PCT and taking 2ius of HGH every day 5 on 2 off (been on the HGH for 3 months before this). I don't know if the decrease in Endurance is from the IGF or just because I am in PCT. Amazingly enough I have not lost any size or gained much body fat.
