Currently about 11-13% bodyfat so fairly lean, just want to kick my vascularity up a notch and heard S4 was great for this. With that said, would it be better to stack this with rad 140 or LGD 4033. I want to lean up a little bit more and maintain/increase my strength, hopefully to gain some size too but that's not my primary goal, I'm more about the dry slow gains. I only have financial room to take only 2 compounds for the time being so taking all 3 is out of the question unfortunately. Thoughts?
