supplements

Dear Chris,

       I'm 48 yrs. old and want to get back into the shape I was when I got married 17yrs. ago. I'm 5' 9" tall about 220lbs. and have put together a small home gym. My funds are limited so joining a gym is out. My question is that I hope you could recommend a supplement or two that could help me build respectable muscle for my age and help me lose around 30 to 40lbs. I lift 3 to 4 times a week and walk 3.5 miles 6 days a week. I see so many adds that I'm just plain confused. I know I could benefit with some help. I have currently lost 28lbs to date by just adjusting my diet and walking. I've only re-introduced the weights about a month ago 

                  Thank you
                           Jeff Eastman
