its usually personal preference anyways. cant really ask wut tastes better, a big mac or a whopper without trying both for urself and see what u like better. everyone's body is different and until a magical product comes out with the same proven results for everyone's different body chemistry, ur just gonna have to go through trial and error. super pump 250 didnt do shit for me and either did no shotgun. no explode works awesome for me everytime i take it! just like cellmass doesnt do much for me but size on does. its all trial and error until you find out what works best for u then stick with it. ive never tried amplify, might check it out and see how i respond to it.
