If you live in a country where steroids are legal, it is not difficult to buy Proviron at all. In fact, you can probably find Proviron for sale in numerous pharmacies and drug stores. However, if you live in the US, UK, and certain other countries where steroids are illegal without prescriptions, you may find it more difficult to buy Proviron. The internet is often a good source, and you may find shippers willing to send Proviron to you through the mail. This is quite risky, though, and it may lead to legal trouble. Learning where to buy Proviron tablets can be tricky, so it’s vital to do your research.
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.
