Sounds like you still have room for natural improvement bro. It's a good idea to max out your natural potential before jumping into a PH or AAS cycle. If you still have a gut and want to lean up, you could take Lean Xtreme and that'll help shed that gut and lean you out. There's also all kinds of creatine supps you can take for strength and size. Get you some Jacked for a preworkout and you'll want to throw 100 pound dumbbells through the wall. Get some Xtend for your intra (during) workout to help fight fatigue and some Torrent for your postworkout. That's a pretty good stack right there for some good strength and size gains while keeping it lean at the same time. You're about my size, so I recommend you take 3 multi-vits a day, couple fish oils, 3+ protein shakes a day, a cheap ZMA supp for sleep recovery, and lots of protein, complex carbs (fruits, veggies, whole grain), and vitamin C.
Hang loose on the anabolic stuff for a little while longer. Once you use a PH or AAS, you risk jacking up your hormone levels and if you still have natural potential you can achieve, you won't fully benefit from an anabolic. With your height at 6'3, you want to be around a weight of 200 or so with your body fat lower or equal to 10%. I'm 6'3 as well and I weigh 213 with a bf% of 8% last I checked several weeks ago. If you still have a gut, you're probably not ready yet.
