desperate to move forward in my career

:woot:yes i am aware that steroids are bad for you; please do not respond to this forum bashing my choice to take them. i am a decent swimmer who needs to be great. i am currently a lifeguard for my county and i am making 11.50 an hour. i want to move up and work at another place, i wont say where, and make 19.50. point is i need to know what steroid is the best for a swimmer to take to increase my run and swim time. is there a steroid that increase endurance and speed while helping build lean muscle? assistance in this matter would be greatly appreciated as i have respect for swimmers abroad. thanks for taking the time to read my forum i look forward to hearing responses..
