Well, Been on BSN Volumaize for 4 weeks now, had decent strength gains, but recently added Shotgun V3 to my stack, and my body responded really well to both of them. Been adding 4kg every week in some cases, instead of 1.5- 2kg, of weight. With good form. Ofcourse i wasnt being wise and on my shoulder day, doing lateral raises i slightly pulled left side of my neck. Was just lifting heavier weights than because i can, not that i should. (had good form. Be careful. Thought I put my 50p worth lol.
