Im going to mexico in 3 weeks. I would like to do a 8 to 10 week cycle after I come back. I wanna know what is the best gear for me to buy that will gain me about 15 pounds and keep most of it besides leaning me out with no distinct side effects. I wanna know what should I buy and how much of it. Im 5'11 and 185. I have been working out for 5 years and I am fairly strong. I am not to big into TEST.
