what are some of the side effects when using insulin? I've been on novalin R 10iu's before my workouts for the past year off and on. now I do 5iu's when i wake up and add in 5iu's post workout. so 20ius total per day. i'm also using hgh, test, and hcg. i've noticed after bumping the dose i have some pain in my abs/ribs and when i stop the pain goes away.
