If you are looking to make gains and you are using tren and sust, and you are not well on your way to your goal. something is off with your diet. There is no magic drug, that when added a a cycle, it's the key to making everything feel 100%. ZThe gains should be coming now and they should be coming well. If you want a mass gaining drug to add to this stack, EQ would be great.
But why don't you ask me another question, this time about your diet and training. Break your diet down for me, as in how old you are, how much you weight and how much you eat of which macro. From there, I can better advise you
