    very nice igf1 supp, me and my brother love it. I'm getting ready for my first competition in the spring and he was training for the Cutler Classic, but got injured mid-way from training so he's aiming for another comp in the spring. Skin started tightening, veins showing, burning calories all day. tastes like vodka lol seriously. We would wake up feeling brand new, I mean i really could go on and on. 5 stars from both of us I would give it 6 stars if it let me. LOVE IT!
