Hmmm Good question though I LOVE Methoxy-7 for your goals etc. and that you are currently taking Carbolin 19. I would say stick with it and probably the Alpha Male.
Boy though choice though I would do Carbolin 19 and one or the other. Thing with Methoxy-7 is that some people dont see much from it and others like Myself do. Its more visual though IMO, keeps me fairly Vascular even at a higher BF%. Then the Alpha Male. at the VERY least people report better energy/libido etc. Thats why I said it. Some report a raised Hunger as well which would aid the bulking.
OK Hope that helps confuse you more.
