need help here

Im 23 5'7 145 lbs. have been working out but it seems that im not getting bigger but I am stronger though. If anyone could give me a sample of diet for me and what kind of supplements that i need to take. I only take 50 grams of protein after workout. thanks !

whoa....diet, check the diet section. You dont need any supplements until you get the diet down.

Can you post your diet? It's probably lacking. Shoot for 2.5k-3k calories.
