I say these three things will help w/ strength/mass gains better...write this down...ready?
Lots of calorie dense foods(red meat, eggs, chicken, oatmeal, brown rice, milk etc...)
Hard/heavy training focusing on the compound movements(Incline barbell presses, dips, squats, deadlifts etc...)
Lots of REST...(8 hours of sleep NO MATTER WHAT and if you can...a nice nap a few times during the week.)
Or like 'an123' says which I agree...pawn those and get the 'real thing' or get a good MRP and creatine. Holla!
