take gnc 1850 weight gainer.. i gain 4kilos by the first month

here is a tip from me.. last year i was 49kgs.. now im 55kgs n still growing.. eat oatmeal for carbs before workout.. after workout eat as much food as possible. i train 3 times a week at 45 min per session. each week, increase your reps by 10-20.. untill u reached a certain point.. then u switch it up to a more advance thing for example from regular push ups to diamond.. after workout or if your not exercising, drink plenty of water as it prevent you from getting water retention.. hope this helps..
