i mentioned on onother thread that i was thinkig of running a 10 week cycle with test cyp, sus250 and trenE. The thing is that i hear that you lose endurance with tren.So what i want to know is how bad of endurance do you lose for example i usually run 1 mile in 8min 40 sec, will it be so bad as to where i will run it like in 12 min. I am looking for your personal experinces on the loss of endurance while on tren.,and if it is that bad i might as well stick with decca.
