Go to any message board, and at some point in time youíll find threads where people are asking how to inject steroids in some of the most ridiculous ways imaginable. Youíll find those asking how to inject steroids intravenously and if you search long enough you can probably find threads where people ask how to inject steroids into their scrotum. Letís be clear, very clear; you do not inject anabolic steroids intravenously. Anabolic androgenic steroids are meant to be injected into the muscle tissue, but some steroids can also be injected subcutaneously.
