There’s overwhelming evidence that Americans and Canadians are in the poorest health overall, considering the health care we have available. The health care we’ve got our hands should make us one of the healthiest nations in the world. However, we rank very low on the list. Most doctors and scientists contribute this to the foods we put into our body and also the chemicals that we come in contact when eating, working, and enjoying. For your health options that we have available to us, we have among the greatest rates of cancer, heart disease, diabetes, and childhood cancer rates in the world.
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.
