Of course, every sensible athlete understands that there are no anabolic steroids that do not have a number of side effects. Some of them have a rather modest list of side effects, which are overlapped by the use of one, at most – two drugs. Others have such an impressive list of attendant “surprises” that they can frighten inexperienced athletes. Anapolon and side effects that you will see are pretty inseparable couple. This is the main reason why he is popular with experienced athletes who know most of the “chalks” not by hearsay and know not only their enemy in person, but also ways that allow him to effectively resist.
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.
