ben i have heard that weight gainers are just a way to put on fat.they are junk things.for example,a guy told me that he bought eas' mass factor and he is still trying to send away his redundant fat.in my opinion,you should buy a whey.but if you want to continue taking this gainer,ok,no problem.you decide.if you want to consume carbohydrates,you should take maltodextrine and dextrose,post workout.here,in Greece,you can find dextrose in drug stores and maltodextrine in super markets.i hope i helped you as much as i could |
