I'm 38 and did my 1st cycle at 22 my dad competed so I was around the lifestyle growing up he always would stress to me to go as far as I could naturally but I made my mind up an old pro Don Long kinda guided me on the right way to go about it. I did test only 400mgs pw for 10weeks then I followed the time on =time off for year's then after awhile I just stayed on test yr round
