You shouldnt even mess with insulin until you have done extensive research. I dont mean to sound like a dick but you dont really sound like you read up. The 10 mark on your syringe is 10 units, but if your in your second week you should know that already. As for your dosing, you shouldnt really go over 10 units otherwise you would have to take in a shitload of carbs and risk making yourself diabetic, its not worth it. You would especially have to watch out if your using humalin R because its a little longer lasting than humalog. Unless your a competitive bodybuilder and have been using AAS for a while I wouldnt even think about using insulin. Granted it can be a little bit of a quick fix, but the risks are too great especially when you dont know what your dealing with.
