Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.

Inevitably, one of the first questions many individuals will ask themselves shortly before their 1st injection is “where do I inject?” While there is no right or wrong answer, the most commonly injected muscles among first time users are the glutes and delts. Both muscle groups are relatively painless (potentially), do not have any major veins/arteries near the surface, and contain a lower density of nerves. Quads are another popular bodypart used for injections, although one does need to be a bit more careful when injecting in this area, as there are more nerves, veins, an arteries in the area.
