Is it possible to improve my bench press 62 pounds?

in 2 1/2 months. I am 18 years old and have been working out for 4 months now including bench press. I'm 213 ibs, 6'2. The supplements I'll be taking will be ON Pro Complex, ON Complete Protein Diet, Kre Alkalyn (Creatine), and ON's Casein. Right now I'm benching 125x9x3, and I want to be able to do 187x9x3.
