dont run tren first cycle... find some test enanthate , cypionate, sust. prop if u want but need more injections and hurts more for a first timer. Test baby!
Tren for a first cycle could be a good idea, depending on your stats and your goal. But it could also be a nasty experience. I'd do something simple like sustanon/dbols (or another test of your choice) and keep the tren for your 2nd or 3rd cycle.
