test 250 & fizogen

Greetings to all. My handle is Popi and I am new to this site. I am a novice lifter trying to get my out of shape 40 yr old 5'11" 250 body back in the shape it was in 8 yrs ago (190lbs.) I recently purchased a couple of bottles of Impact Nutrition Test 250 and some Fizogen on & off cycle (non) cali formula. I need to know if any one has taken these sup's and how I can get the best out of them by either taking them individually or combining the two in a stack. Any help would be greatly appreciated. Thanks
