hi guys , i am on 49kg and 173cm , and may i know which protein
will let me gain more weight other than eating? because i have been
eating more than last time and my weight gained from 47.5 to 49 , i
was on isobolic protein , but due to my busy schedule , i do not
have the time to train. That is why i do not have the chance to
take isobolic. May i know is the protein mass gainer will be better
for me?
