I waited till I was 27 and had 12yrs of lifting experiece, and am now reaping the benefits. Lifting for me is a life long passion. Dont be in hurry to buy some gear thinking that is the ticket. Learn the fundamentals, practice them. Then try as many forms of training you can find. These will be your experimemts in finding out what works for you, and this will also keep you growing. Finally, learn about nutrition, eating for size is the most anabolic thing for you, its better than any steriod or supplement out there! Thats my .02cts. Good luck!
