The biggest risk of all will always be legality if you live in a country where anabolic steroid use is prohibited without a prescription; if not, use and enjoy with the liberty granted you. Beyond legality, as with all forms of steroids there is a risk of potential negative side-effects; understand, “risk” simply means risk, it does not mean certainty by any means. Of the risk commonly associated with Dbol high blood pressure is the most common one and if there is any negative side-effect you’ll need to keep a close eye on it is high blood pressure. Blood pressure aside you’re not completely out of the water yet; Dianabol steroids can present the risk of Gynecomastia or what is commonly known as “Gyno” or “Bitch Tits.” Even so, unless you are ultra-sensitive to gyno, if you use an aromatase inhibitor throughout your Dbol use, in most cases you will be in the clear.
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.
