6'4 182 lbs.

Continue training and eating religiously, you need to go up to at least 200pounds before you look anything like a natural BB. Just a simple plain fact.

You are only 18, which means you have about 5-6 more years ahead of you to grow and naturally fill in, so be patient and do NOT ever turn your back to the gym only because this could be a slow progress for you.

.... and lastly, forget about ostentatious yet useless supps. Buy yourself a decent whey protein (Optimum, Muscletech, Gaspari, Dymatize, Ultimate and etc.), once scoop about 30-45 mins. before you hit the gym with some natural apple juice and another scoop immediately after your workout with again some sort of natural carb source. Creatine Mono will also make a difference by drawing water and glucose into your trained muscle fibers, you can add 5gr to your post-workout shake and drink it up.

At some point during your training regimen, you will however have to switch from the pyramidal workout system to power training system for better results concerning muscle bulk and incremented overall strength. Nutrition will help you so far, you have to start introducing your fibers heavier weights and lower reps. Do some research on the 5x5 training regimen, you will have a much better idea of what I am talking about here. Nonetheless, when you are bodybuilding for hypertrophy, you will still need to go through one or two power training phases each year, each phase lasting for about 4-6 weeks.
