Almond, I wish you the very best man.. But i think you need to make your way over to the workout and diet sections of this forum.. because there are much better ways to make gains and long term ways to grow than to just start injecting at 22yrs old and 120lbs.. and there is no math or chart that will ever equal what a gain is for two different people of different builds. pull up the Mr O pose pictures, and see guys all standing next to each other most of them around the same weight, and u can see even at that level body builds and muscle is totaly different..
I understand you want to get bigger and grow. heck I have a brother that is 125lbs and probably stay that size even though he is really strong and works out....but even him its because his diet is for shit mostly.
man out of all places in the world. this board can help you the best, you have everything from real body buildiers to people in medical field to certifeid trainiers giving free advice... but just like neo. we can lead you to the door, its you who has to open it...
