Steroid drug testing
Choice of such subjects guaranteed that small effects of AD which might be of great relevance to athletes would be deemed statistically not significant - not reliably distinguished from chance - by this study. steroid drug testing Us steroids. Overfat individuals were used as subjects. Starting bodyfat percentages were over 23% for the AD group and over 21% for the placebo group. This might have affected conversion to estrogen,2 because much aromatization occurs in fat tissue, and in any case such subjects are hardly representative of athletes. steroid drug testing Steroid side effects pictures. Subjects were on a diet atypical of athletes, receiving only 85-98 grams of protein per day. This is shown in various studies to be inadequate for individuals undergoing resistance training. 3,4,5 It cannot be ruled out that the reason the AD and placebo groups gained the same amounts is that protein consumption was the limiting factor in each case. steroid drug testing Bodybuilding pics. Failure to control diet essentially guaranteed inconclusive results with respect to fat loss. In short, the methods used were such that it could not have been rationally expected that possibly important effects of androstenedione (such as perhaps raising testosterone levels by 20% or 30% during a window of a few hours, or improving ability to lose fat by say 1/4 or 1/2 lb. per week, or improving strength of a trained athlete by 5%) could be detected. If they did exist they either were not detected, or if detected were deemed not significant because they could have occurred by chance. In other words, the study was born to fail. Valid Conclusions to be Drawn from the DataWhile the study was not capable of determining if small increases such as 20-30% occur from the supplement or from chance, the study does have some limit of detection though this is not reported and I cannot compute it because the authors fail to provide the necessary data. It is obviously rather high though. The data, though variable, seems precise enough to enable us to say it is proven that testosterone levels are not increased by 200%, or perhaps the data is good enough to be able to say that testosterone is not increased by 100%. The authors did not perform the necessary calculations to determine exactly what limit might be set, and instead conclude that there is "no effect. "Work done elsewhere proving with 95% statistical confidence that increase does occur6 is not disproven by the JAMA study. King et al. cannot state with even 50% confidence from their data that there was no increase (since after all they did observe an increase). One simply cannot claim, as these authors did, that one's observations of an increase of about 30% prove that there is no effect!Nothing can be concluded concerning fat loss because the data is too variable. AD may be beneficial or it may not. It may be concluded that no adverse effects occurred on markers of liver function or on LH and FSH levels.
