I need some advice been reading a lot on insulin and been thinking about starting a cycle but I have a couple of questions first. Is there that much of a difference in Humalog verse Humulin R? I think here in California U can buy both over the counter and second I work all day and don't get to the gym till around 4:15 PM work out till 5-5:15 PM this is when I would take my insulin shot, my question is how long would a guy have to stay awake to be safe? I usally go to bed around 9-10 PM Thanks
