Just need a few tips for anyone who works out in onRPG.
I'm currently 15, turning 16 in a few months. I've been going to the gym 3 times a week for the past month already, and i was wandering if theres anything which I can do to bulk up a little.

Weight: 52kg;
Height: 165cm;

I can bench 40kg with no support/ 45kg with a little help balancing. For dumbbells, I can do 8kgs (10 reps). I've been taking (Musashi Bulk Blend Protein Shake) once a day, and there seems to be little effect. My family friend told me that it would be better for me to get a carb shake which will buff me up faster.

Suggestions?
