Well, most of my research has been geared towards bulking, mass. ect. I am running dbol as of now and you know how that goes... I get out of breath typing too fast. Anways, after this cycle I want to get in better shape cardiowise, and I think that certain gear will enhance your red count, thus enchances cardio??? I smoked for 4 years and never really got into shape after I quit. I want to get into shape badly... Just curious if there was anything out there to help in that area. Thanks X.
