Here's more information for people to understand the huge difference between injectable steroids and oral on liver function:
endocrinologists:
- Dr. Michael A. Werner (admittedly he is an andropause therapy guy): There have been no reports of liver toxicity from transdermal testosterone replacement. However, oral testosterone replacement can cause significant liver problems"
- Richard A. Bebb (interestingly this guy was my endrocrinologist who is not into steroids or andropause replacement) "Liver toxicity is an exceedingly rare side effect that tends to occur only with some of the oral testosterone preparations."
Here's a medical endocrinology exerpt from Google books listing some steroids. Note that the one that says liver toxicity is specifically 17alpha (modified for liver processing, oral) while others specifically so "no evidence of liver toxicity".

Google books search hit on the Sports Science Handbook: "Oral steroids generally have more serious side effects compared to injectable steroids, with a far greater incidence of liver, kidney, cardiovascular and immune system problems being reported."

Here's another Google Book search result (this book is pro androgens) that says "injections, transdermals, gels, do not share this liver toxicity":

Here's one where for guys with low testosterone, their liver function actually improves with testosterone:

Here is the Drugs.com listing for androgel side effects details based on the clinical studies. Note no liver toxicity listed.

"Testosterone cypionate, testosterone enanthate and other injectable anabolic steroids seem to have little adverse effects on the liver. "
Anyway, all sex hormones do get processed by the liver, but "regular" (natural or injected) are processed relatively slowly and don't do much more stress than drinking alcohol. Oral steroids though get excreted if they don't get 17alpha methylation which is used to make them potent, but prevents the liver from getting it out of the bloodstream and apparently damaging the liver at the same time.
I agree that very large doses of regular testosterone would also stress the liver, but generally it is really not a stressor, and again is in line with regular stress put on with other normal lifestyle choices.
I've obviously picked the information that supports my view, and recognize there is other views, but my point is that there is a fair amount of real medical opinion that injectables are either non-toxic or mostly non-toxic. This is to refute your claim that our view is unsubstantiated and uneducated. I agree that like many drugs there is controversy on the subject -- but so is for most medications: check out the controversy over statin drugs (there are doctors that believe they don't help heart disease at all for most people). But you saying there is no medical basis for our claims is flat out wrong.
I think the thing that you don't understand is how extremely health-conscious bodybuilders are. I am vegetarian for the most part, don't drink unless it is a social occasion and then only moderate and only wine, don't eat any fast food, don't smoke, keep very healthy weight, exercise two times every day for over an hour (and exercise very intensely), eat multivitamins, etc. I look at health for the long term and in fact philosophically believe that people in our generation have the opportunity for serious life extension as our medical technology improves. So my support of judicious use of testosterone is based on very careful thought, years of study, and years of experience. It is not about short term gain for long term loss, it is a calculated attempt to maximize my life meaning feeling as well as I can for the biggest portion of my life that I can.
I admit that there are some health risks, but even then I'm not taking many of the health risks that others take, so call it my one indulgence.
You need to have some perspective -- there are now medical opinions saying that sugar (any amount) is toxic and will kill people in the long term and is causing majority of diabetes and fatty liver problems so prevalent today. Every building I go into at work has a warning sign that says that the building is known to contain cancer-causing materials. People happily ate trans fat for decades. People who ride motorcycles in my opinion have a death wish. Looking at the list of side effects on any drug (check out ibprofen) is scary, and can only be judged personally.
But your rabid anti-testosterone stance is really untenable. I object to your attitude and your specific claims about liver toxicity. A balanced opinion would say "there are some health risks, especially related to heart health and some cancers, that should be considered. Stick to modest amounts of injectables, and get your blood work done regularly". That is how you help people and possibly change their opinion.
