The Common Trait:
As mentioned the majority of oral anabolic steroids can be a bit toxic due to a very hepatic nature. With many oral anabolic steroids liver enzyme values will increase dramatically with use but do not let your heart be troubled just yet; well explain as we go along. The reason for this hepatic nature is due simply to the way many of these steroids exist. As you understand simply ingesting something orally is not always the most efficient means of administration; for example, if you were to take a bottle of Testosterone-Enanthate and you were to drink it your body would destroy most of it before it ever made it into the blood; in-fact, youd be doing good if even 10% of the active hormone made it into your blood stream. For this reason many oral anabolic steroids are C17 Alpha-Alkylated, often referred to simply as 17-aa anabolic steroids. What this means is the hormone has been altered at the 17th carbon position in order for it to survive; without this alteration the hormone would be destroyed during its first pass through the liver.
This 17-aa structural change is necessary for the hormone to be usable by the body but unfortunately it creates a toxic effect regarding its interaction with the liver and as a result liver enzyme levels go up. How toxic is it? This is impossible to answer outright as the level of toxicity will vary with each and every oral anabolic steroid and dosing and total duration will come into play. However, regular alcohol consumption is far more toxic to the liver than any oral anabolic hormone and many over the counter medications carry with them a higher hepatic nature than most oral anabolic steroids. Further, the liver has amazing healing properties and if the individual supplements responsibly no permanent damage will be done. For the responsible user once he discontinues use, assuming no other oral anabolic steroids are being used and no other liver damaging factors are in play, such as heavy alcohol consumption the liver will be fine and enzyme levels will return to normal very quickly.
Safe & Mild:
While many oral anabolic steroids are very toxic there are those that carry a very low hepatic nature and are in most cases very side-effect friendly. Such steroids are very popular among many female athletes as anabolic androgenic steroids can in many cases be very problematic for the female athlete. Many anabolic steroids cause virilization in women bringing about effects that destroy a womans very femininity but thankfully there are some steroids that can be used by the female minus this effect. Of the ones that can be used, the oral anabolic steroids in this category include primarily Anavar and Primobolan with Anavar being the most popular and effective. While oral Primo as it is most commonly known will work it is not as effective as the injectable version Primobolan Depot and most women will be best served sticking with Anavar.
