Lr3 is way more bennifiacl post workout. Of course you can use it pre-workout, but Des2,3 is way better for pre-workout. Not to mention that the pumps from des litteraly last all fckn day. Now I have never tried MC's IGF, but it's really gonna be hard to beat the des i been using. As soon as I get my Igf from MC, I will do a comparison thread.
