I am 48 yrs. old and taking creatine, Amplify protien,glutamine and P6 a test booster. I see gains but slight. I still am active in MMA and I think with all of the above I stay fit more than I would if I wasnt taking it. I have heard I have to cycle off the Test boosters, but have also heard at my age it is OK to keep Test levels high in your system? What are your opinions? I need to some tips on geting bigger and leaner. I am bulky but still carry a lot of extra. I cardio 4 times a week and lift 3 times. Any suggestions on better suppliments? Thanks for your time.
