Jbry, there are really no studies of supraphysiologic studies of any anabolic steroids, be it injectable testosterone or other compounds that convert to test one way or another. I'm not sure though I'm sure the russians took data of their athletes using aas, but I'm not sure any of that was released to the public. Very hard to use the scientific method to verify the data. Too many variables. Most of the randomized double blind studies of any hormonal substances are based on either transplant patients, specifically lung transplant or others with severe metabolic imbalances, or hiv/other wasting disorders. I am not aware of any studies on healthy men that have tested a higher than trt dosage of test, or any other anabolic steroid for that matter. No money in it for the pharm companies. Anecdotally there is plenty of evidence to either side of the arguement. I feel that for me personally, I'd rather run 8 weeks of test p at 400mg/week vs superdrol, or any other oral compound at a dosage that will be comparable to test at those levels. To me I get a safer cycle, as far as liver enzymes go, cholesterol I'm not sure as the only evidence on superdrol and most steroids on lab levels is from anecdotal evidence with many variables, out of test vs superdrol for the same time. I will say this about orals. At lower dosages or safer dosage ranges orals can be run indefinitely as long as one is consistently checking their lab values. I have patients who have lung transplants, go on ecmo, recover and are severly malnurished even though they are on tpn, tube feeds, or even high calorie diets with supplements of hydrolyzed whey four times daily. These patients are typically put on about 10mg of anavar either once or twice a day. They show increased weight gain, appetite, energy, muscle mass gain, etc. I have seen these same patients also on statins, prograf, prednisone, cellcept, and plenty of other meds including heavy antibiotics. Some of them show a slight increase in lfts, some of them don't. Some show an increase in bun and creatinine, some don't. Many of these patients, if men, are also on androderm patches. Seems to be fairly safe, but once again those are very low dosages. So as far as is there a difference in gains from someone taking andriol vs test e for the same period of time, at comparable dosages, then probably not. Is there a difference in lab values from someone using oral steroids vs. injectable steroids, yes, sometimes injectables are worse, i.e. tren, sometimes orals are worse i.e. superdrol, cheque drops. There really are no definitive answers, I will say that I personally prefer injectable test vs any other form of orals that will convert into test. And as far as what is the difference to injecting test into your butt, to those who have ran injectables then I assume they would know, the mental aspect of injecting yourself is great motivation. I get more pumped shooting myself before a workout than any preworkout or oral could ever give me. The risk for addiction, in my opinion, is much greater to those injecting vs those who only take orals. Interesting convo though, is there anything else you want my opinion on?
