I'm reading in IGF, and I had a question about this.
The IGF protocol is 4wkon/4wkoff, and I know IGF acts like insulin, so also will decrease slin sensitivity. I know a guy that takes igf 4wks, and in the 4wks off he takes SLIN. So its like this:
1-4 IGF LR3
5-8 SLIN
9-12 IGF LR3
etc....
This is a bad idea right?
