I feel that a lot of steroids help with drive, which in turn helps with endurance. Tren is maybe the big exception, as it will give you the opposite effect. If you are new to gear, sure, I think that a little anavar will help. I wouldn't go on building my cycles around orals in the future, as they are often more dangerous than injectables, but yes, if you want to use var for a sport, I'd suggest about 20-30mg ED for 6 to 8 wks, split into 2 doses a day. In the future, I would consider looking into a low dose of test along with EQ. With some adex, you can control fluid from the test, the test will support your body's normal functions and the EQ will dramatically increase RBC, which will bring more O2 to your blood and vastly increase endurance.
