i am a type 2 diabetic, i am 47 years old and was positive three years ago for diabetes, i am 6 foot 3 and weigh 270 been pumping all my life. the only way to get big and strong is proper diet and training, i am in the gym seven days a week, your boyfriend is putting a gun to his head with steroids and rest assured all the bodybuilders are doing steroids, he needs to stop this before he ends up in the emergency room, yes it is tempting to get big quick but when he stops all the size will go away, at his age he is still young and dumb so take out a good life insurance policy on him and reap the benefits.
Your boyfriend should be more careful about his diabetes and stop taking the steroids. A book by the American Diabetes Association recommends frequent checking of blood sugars if prescribed a steroid by a doctor.Your boyfriends diabetes doctor should be consulted as he would know where to get help and how to stop the cravings for the steroids. 5'11" and 220 lbs. is certainly not small, as i'm 6'4" and 183 and don't think i'm small. i don't understand how people get into those mind frame where they are perfectly normal and think their body size is too small. i'd recommend psychological counseling for that, which may be part of what is necessary to stop the steroid use.
He should be checking his blood sugar frequently as it may go high as well with all the extra sugar he is eating. i have had diabetes for 31 years now and i understand how difficult a lklifestyle that diabetes enforces on us but for a normal lifestyle as possible keeping your blood sugars as close to normal as possible is a must. Please recommend he see a doctor. Good luck, bret
