As a result, it is also impossible to set a scientifically or legally sustainable threshold level above which a doping offence can be proved to have been committed. anabolic store Buy online anabolic steroid. Other Reasons for Positive Nandrolone Drug TestsBesides all of the above there is the issue of the presence or contamination, intentional or not, of an athlete's food, drink, and nutritional supplements by compounds that can result in a false positive nandrolone drug test. For example, a recent study (Le Bizec et al. , 2000) has shown that this can occur from the consumption of boar meat. anabolic store Male-bodybuilding-gallery. Where Are We Today?Unfortunately not much has changed. The IOC, of necessity, is still defending the status quo and is still in denial when it comes to acknowledging that the use of their arbitrary NA threshold levels for the detection of exogenous nandrolone and the nor prohormones may be severely flawed. It's been adequately shown that norandrosterone and noretiocholanolone, and likely nandrolone itself, are endogenous hormones in man. anabolic store Pictures-of-steroid-users. Thus, as we have seen, it's the amount of hormone metabolites found in the urine, rather than the presence in the urine, that forms the basis of a positive doping test. In my opinion, because of physiological and possible pathological parameters it is impossible to call a drug test positive for nandrolone because the nandrolone metabolites are endogenous compounds involved in the formation of estrogen (perhaps secondary to the decarboxylation of 19-carboxytestosterone or from androstenedione by way of 19- norandrostenedione), unless significant levels of metabolites are found in the urine. There are several reasons for my opinion:Lack of Data on the Endogenous Metabolism of the Nor steroids. Foremost is the dearth of scientific and medical data that substantiates the decision of a positive drug test. What is known amounts to an acknowledgement that nandrolone, or at least its metabolites, are endogenous steroid and from a few small studies that the urinary levels of it's metabolites are assumed to be very low. As such a cut off level of 2 and 5 ng/ml has been set for men and women respectively as the upper limit of endogenous NA in the urine in an internal IOC Memorandum in August, 1998. Even in this miniscule sampling it is obvious that even in normal people that this contention is wrong since an early study found elevated levels of NA, between 9 and 37 ng/ml, in three male volunteers who had not used the anabolic steroid nandrolone. Regardless, there are no substantial amounts of information from large populations of men and women, under different physiological, psychological and pathological conditions, on serum and urinary levels of 19-nor androgens and other nor compounds. Variations in the level of these compounds, since they are part of the sexual and reproductive steroidal milieu, would logically occur under various conditions, in both men and women, including in women, the various menstrual stages, pregnancy (including the first trimester) and in both sexes secondary to various physiological and pathological states. Possible Reasons for Elevated Levels in WomenAs an example, there is no information in the scientific or medical literature that records the changes in the 19-nor-steroids around ovulation when there is a surge in the gonadotropins and in testosterone and estrogen secretion. A gonadotropin surge seen as part of preovulatory complex of endocrinological and physiological alterations, resulting in an increase in endogenous testosterone, epitestosterone, estrogen and likely nandrolone (given it's intermediary role between testosterone and estrogen) would explain any elevations in all these steroids that might be found in a female athlete's urine. In women, another possible reason for any increases would be an incipient pregnancy in which there are alterations in the gonadotropins and on steroidogenesis. Whatever the reason, endogenous origin of nandrolone would likely be accompanied by across the board elevations other urinary steroids,, including testosterone and epitestosterone. These elevated levels would argue against the use of any exogenous nor steroids. Any use of exogenous nandrolone or even any of the nor-steroids available over the counter, would not likely result in concomitant increases in testosterone or in epitestosterone in urine samples. The use of exogenous nor compounds would (as is seen in the use of exogenous testosterone and anabolic steroids) likely have had an inhibitory effect on the gonadotropins and on endogenous steroidogenesis, and as such on the serum and urine levels of testosterone and epitestosterone, which would be decreased, accompanied by elevations in NA and NE. Thus the actual use of nandrolone or continued use of the prohormones would have other effects on the hormonal profile that would be directly opposite the profile that would be found if there was a natural increase in steroidogenesis. See the Appendix 2 for more details. Possible SolutionsRather than depend on arbitrary cut off levels, the IOC should pursue other methods that may distinguish endogenous and exogenous compounds. At present IOC accredited laboratories report a possible positive when the ratio of testosterone to epitestosterone is more than 6 to1. But as pointed out by myself, and several others over the past two decades, this ratio can be exceeded without a doping offenses being committed.
