Of course you can, and you should. GH and some gear to go along with it is the best and smartest thing you can do. Not cheap though, but if you know where to get both a t a decent price then thats the way to go. Insulin obligates us to get a life vital diet , cuz of the carbs ingestion , i say its not worth the isk, also insulin is momentanious, it dosent last long and you only look swoolen for the time you are on it.
