You can get Humulin R and the generics of it at a pharmacy just not Humalog.
The thing is with insulin, it has that risk of death, yes. But its not as dangerous with common sense. Diabetics don't die. Yes, there bodies process and are different from someone who is not and taking it but the concept is still the same.
It can change your physique for the better or worse if you do not know how to properly use it. But you have to ask yourself, have you really used all the available AAS that can do that as well? Are you going to take bodybuilding to the level that the possible risk of death, worth it? Or are you just a weekend warrior at the bars trying to look good?
