Newby here I posted on the newby page but didn't get much help. I'm a football player and I've done 1 cycle of test and winny about a year and half ago. I want to do another and train for speed and quickness. I don't want to run a long cycle and I want to try tren at a low dose w Clen andor t3. And test obvi. But if it truly will effect my cardio that much I'll reconsider and I know var is a great choice for this but like I said. I have my eyes on tren. I just want advice on what how and why. Thanks.. Btw I'm 22 5'10 210 and I've been injured(ankle) so I need to get my cardio in check.
