Promatrix Advance Muscle Mass Gainer
Hey there. I just discovered this page today. I was wondering if you could help me.
I'm 21yrs old, 63kg, 5'7 and I lift weights 3x a week. My Promatrix Advance Muscle Mass Gainer just arrived today and I'm not sure how much and how often should I drink this. I want to gain muscle especially my upper body. Please help me. Thank you!
