What's up guys? I like to do allot of cardio and am wondering how a 12 week cycle of Test E at 500mg/wk with Winny at 50mg/ed for the last 6 weeks would effect my cardio. Currently I do 20 min. post WO at a HR of 125bpm every WO day. (4 times a week) I also do 2 days of 400m sprints (4 or 5 sprints) EW, and a 4-5 mile run on one of my off days. Can I expect to keep this up, or am I going to notice a drop off in endurance? Thanks
