biggest thing to remember when using insulin is DON'T BE LAZY when it comes to eating.
if you wanna get as much benefit and as little negative's you must
#1. Have protein/amino's in your stomach before you take your shot(s)
#2. Avoid fats... this means do not eat fucking cookies, brownies, ice cream,... no cinnamon rolls with butter, ect... for your carb's (as they contain fat). No whole, 2% or 1% milk... if you drink milk, it's gotta be skim... same for eggs, they better be egg-whites. Sure as hell no peanut butter.... no fatty steak.. if you eat ground beef, it'd better be the leanest you can find, and strained and rinsed with water before you eat it.
#3. Watch fat content in your protein shakes. Concentrates have higher fat content than isolates/hydro's.
generally speaking, 2-3 doses of 5-15iu should be plenty.
for example;
am/breakfast - 7am, drink 50g hydro or isolate. 715am 15iu humulin R. 730am, 10g bcaa + 60g dextrose + 60g fructose. If by 8-810am you're still feeling hypo (sweaty forehead, shakey, quick pulse, 'high' feeling, ect... everybody's different), drink down another 20g of dextrose (or 20oz Gatorade.. hell, even Mt. Dew will work)
12pm/noon, repeat the same drink/food, except with 5iu humulin R and cut the dextrose and fructose down to 25g-30g each.
either post-workout or before bed, repeat the same thing you did for breakfast... if before bed, add in 30-50g maltodextrin and an extra 30g isolate/hydro.
