I'll give a quick break down about myself

Age: 18

Height: 5''8

Weight: 148 lbs

Bench rep: 185 (x10)

Bench max: 225

I have no history of any serious health problems, I wan't to really build my biceps, pectorals and abs. What supplement could I take that would help me with this goal and does not have any bad side affects like hair loss, liver disease and so on. Also something not to expensive.

Thank you very much for any help.
