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.
I have been using anavar for the last two months and have gotten amazing results so far. I am a 20 year old female and although i was already very lean before beggining my cycle my goal was to add on 10 more pounds of muscle. I was a little skeptical of it since its a steroid and all and being a girl i was worried about side effects. I can happily say that i have reached my goal with the only side effect being a few pimpes but that is to be expected when putting extra testosterone into your body. For anyone on there either looking to add some lean muscle mass or even shred up a bit for the summer take anavar! its amazing
Anavar is very popular among athletes for the great results it provides and the few side effects it has. Even though it is a mild steroid, oxandrolone helps to build very high quality muscle mass, without water retention. It barely has any androgenic activity, and it has a low level of toxicity. Particularly, the lack of androgenic effects, together with the muscularity it provides, made it a bestseller among male and female athletes. However, when using anavar one should never forget that it’s still a steroid, and safety precautions must be taken.
