been on and off juice for close to 13 years now. but for the past year and a half i have stayed on test at about 500 a week and then cruising for about a month at 250 a week. when i am on 500 a week i have thrown in some tren once or twice during the past year. but mostly just on test. i am 34 years old now and was wandering if any of u stay on all the time now and will it hurt my chance of having kids in the future. i have heard many diffrent things.
