As far as supps go, you'll make great gains without these anyways seeing as your just starting it seems, but creatine, BCAA's, Glutamine. Diet wise just go to the bulking section and search diet and you'll find tons of stuff. But generally you want to keep your Macronutrients at about 40/40/20. So 40 percent of your diet is protein, 40% carbs, 20% Fat. Mine was at 25/50/25 but my body is.... out there haha. Start off with 40/40/20 and see how your body reacts to things. Good luck bro.
