Insulin can be extremly dangerous,in case you do not use it properly.Hypoglycemic coma is a critical medical condition that could be non reversible and might lead to brain death.A male bodybuilder who wishes to use insulin,as a part of his off season muscle growth schedule,should be well informed how to use insulin correctly. Insulin is extremly effective as it nurishes the muscle cell,through the transport of micronutrients into the sarcoplasm.Amino acids,sugars,fatty acids,vitamines,minerals,creatine are entering the muscle tissue.However,carbohydrate is the key element in order insulin to work efficiently and safely.It is not only the protein you should care about,but the simple and complex carbs as well.Glycogen synthase is stimulated for muscle and hepatic glycogen formation. Assume a person of 100kg (220lbs) who uses insulin,AAS,HGH. For every 10kg/22lbs of body weight,1 iu of insulin shall be used.That practicaly means that this person have to use 10iu of insulin during the day.This can happen either in two equal divided doses (breakfast & after training),or in one (post work out preferably).For every 1 iu of insulin,10gr of carbohydrates are required for safe use.This equals with 100gr of carbs for the daily 10iu of insulin use.Those 100gr should be 50% from polysacharides (maltodextrine) and 50% from starchy sources of complex carbs (potato,rice,pasta). Mind that the fast acting insulin is way more safe,since it acts in a few minutes,so the user can be ready and well prepared in case of any hypoglycemic effect.On the contrary,the long acting insulin could be tricky,in case hypoglycemia occurs durng driving a vehicle,or even during sleep,that could be lethal. A post workout shake should consist of the folloing ingredients: 50gr maltodextrin with 50gr whey isolate-hydrolysate protein and 10gr glutamine,10gr Bcaa's,5gr HMB,1gr CLA.1gr Ω369,5gr creatine monohydrate,1gr vitamin C and electrolytes.One medium banana will provide another 20gr of fructose,or an energy gel as an alternative choise.
