I have pro-prop its 200mg per ml and i heard the stuff is great but hurts like a bitch, im on prop now that doesnt gurt buts its soon to run out and im hesitant on starting the new one becuase of the imense pain that i keep hearing bout it. I was wondering if i were to mix 20mls of sterile oil if it would lesson the pain. Also my freind just started a prop 400mg a week cycle for 10 weeks how do you think his gains are gonna be.
