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.
“Topical steroid addiction” seems related to an inappropriate, excessive use of topical steroids, which is “abuse” – rather than correct “use”. It may arise especially when topical steroids are relatively easily available and are used without proper conventional and on-going dermatological advice, over very long periods.
Paradoxically another psychiatric term is used in this context: “steroid phobia”- a phobia being an irrational fear associated with avoidance behaviour. It is easy to see how hearing about “steroid addiction” can lead to “steroid phobia”.
Atopic eczema has no single cause: it originates from multiple causes, and the best treatment outcomes are based on this understanding. Conventional dermatological wisdom remains firm that topical steroids have an important part to play in the correct treatment of atopic eczema, and it is much more often their under-use, rather than their over use, that explains treatment failure.
Dental pain also tends to respond well to treatment, whether it is post-root canal, trauma-induced, or idiopathic. I have observed trigger points and symptom-inducing scar tissue to regularly resolve more easily when ozone is added into the treatment protocol. Nasal inhalation of ozone gas that has been percolated through olive oil frequently works very well for pain from acute or chronic sinusitis (it must be noted that if ozone is inhaled without percolating it in oil, it is very irritating and damaging to the lungs 30 ). Patients suffering from chronic infections such as Lyme or its coinfections (eg, Bartonella , Erlichia , Babesia , etc) often have faster symptom resolution when using ozone injections in painful muscles or joints. Such amelioration may be due to a combination of the anti-inflammatory effects of ozone and its antimicrobial properties.
