Hey guys, need some help with this. I am going to come off an 8 week cycle of Test Prop and Tren Enanthate, I was looking into doing a month of IGF1 for PCT to help keep strength and lean down a little bit. Is it true that IGF can cause cancer or make it worse if you already have some without knowing it? If it is true how much bigger of a problem would you have? I am all about trying this stuff out I just don't want to have a problem for the rest of my life with any type of disease. All comments would be appreciated.
