Don't let age stop you. There's bros on here in their 50s, me included, that hit it hard everyday and look good in an under armour tee. You still have quite a few years where natural gains are possible. I ain't got nothing against guys doing gear, in fact I'd say if you are going to, do it while younger while you're body can tolerate the stress better. if you don't have 5 solid years in natural training though I'd say wait until you do. Either way you won't get Derek Lunsford big but you can still gain some decent size and even compete... just not in the Olympia. FWIW I know a guy who is 58 and competes, he started at 50. But as others stated PCP is the best place to start when you have symptoms
