Laxogenin is well known to be the superior agent available that can give you anabolic gains in mass and strength without HPTA suppression, or other side effects associated with anabolic steroids. Therefore, athletes can use it on a caloric restricted diet to prevent loss of muscle and strength. Furthermore, it will also help control glucose and increase thyroid function (metabolism). According to one experiment from the late 80's in Japan, laxogenin has been shown to have anti inflammatory benefits and a prominent anti-tumor potential.
Another great benefit which makes it the most sought after drug by steroid users is that it shows very low toxicity of the liver. Usually other steroids often cause high amount of liver toxicity in its users which make them less popular. However, with Anavar one also gets to experience no fluid retention in the joints during the steroid cycle. Being non-estrogenic in nature, Anavar also reduces the risk of virilization in women and gynecomastia in men. With Anavar, the weight increase after the steroid cycle is also very less, almost negligible.
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.
