Please help this skinny tito [M28; 5’4”; 52kgs]

I am 28 years old but I only weigh 52kgs. (I was only 48kgs 2 mos. ago). Nag gain lang ako ng 4 kilos nung nag-start akong mag-gym at uminom ng serious mass gainer.

Akala ko, based na rin sa mga sinasabi sakin ng nakakasabay ko sa gym, na lalakas akong kumain. PERO HINDI. hahahaha

Meron ba kayong marerecommend na vitamins or any supplement na pwedeng tumulong sakin para ganahan akong kumain?

Already tried Appebon at Appeton before pero walang effect hehe. Planning to stop the Serious Mass Gainer kasi nagiging dependent na ako dun for my calorie intake.

THANK YOU SO MUCH. WILL APPRECIATE ANY RECOMMENDATIONS :)
