Bro, there is a reason the above mentioned products are supported by this forum, it's because they WORK! they are no bs products with one aim - to make you better!
Just read the testimonials or ask anyone around EF about these products...they will tell you that they give yuo better focus, massive pump, lots of energy and better blood and nutrient flow in your body - all essential elements to build a quality physique
Talk to OMEGA, he might be able to get you a deal on some of the products!
Ingredient wise, I can't really correctly/accurately answer that.
experience wise, no shotgun and others gave me better pumps than usual.
However, amp02 made my chest pump so tight that it hurt it was so full. Does it everytime. My back pumps really full vs not much pump at all. It pumps so much you can't use it on leg days with severely compromise your workout. Dude, it is legitimately the best stuff out there.
Not only that, but the price is right.
I wouldn't be BS'ing anyone about it either. I have no gain from suggesting this product over others. I'm just being honest. Read my log in this section titled Ultimate sponsor stack. I give an account of my first day with AMplify02. I will never forget how insanely pumped I got.
