what should i try?

[lmgab]

Im looking to get in better cardiovascular shape for basketball and am looking for something that could help me as a performance enhancer temporarily
is there something i could use to give me more endurance while sprinting and i could use temporarily as an aid and eventually be able to play and do sprints full speed without dying without the need of any steroid.
i was wondering about clen. Do you know if like other steroids, everything gained from using it is lost when get off it.

diet and exercise, clen will help you loose some fat once your diet and workout routine is in order.

Bro there is no magic pill or shot.Sad to say it still comes down to hard work n sweat.

Do lots of sprints...I remember those days..I use to hate sprints, unitl I got in shape. I bustes my a$$ and before I knew it, sprints were no problem. I found myself pushing harder and harder each time. It also made a gatorade and homecooked meal seem like heaven!

the reason im asking is because i have asthma, and a regualar albuterol inhaler doesn't help much.and though clen could help
if i were to use it, would any gains i made while using it go away when i stop because i know i cant keep using it forever.
