Guys, is there a difference between Methyl 1-A and 1-D by LG? I got 1-D from the Vit. Shoppe and am on week 3 with it, and have seen significant increases in strength and I've put on about 6-7 lbs in that short time. Is 1-A better and/or does it have more (if any) side effects? I plan on taking formadrol after a four week cycle of this - need I take it?
