Guest guest Posted April 11, 2000 Report Share Posted April 11, 2000 As a 53 YO Male I am certainly in the low testosterone age group (statistically). Have been curious about the Andro & NorAndros. Did some reading & came up with some interpretations of the info. I am sure there are readers & posters here that have opinions & facts & more info. Please comment, tear me up, educate me..educate all of us. This seems like it would be an extremely valuable discussion. All of members of the Andro family are converted to testosterone by natural enzymes in the body. There are three basic types or isomers of Andro; Androstenedione, 4-Androstendiol and 5-Androstendiol. There are additional variations but these are the three basic forms. There are alpha and beta variations. There are differences in the physiological effects of the major isomers variations. There are individuals and companies that recommend specific alpha or beta isomers however I feel that this is more of establishing a market niche than critical physiology. In addition to the Andro's there are the Nor-Andros; 19 - NorAndrostenedione and 19 - NorAndrostenediol. The Nor Andro's are converted to NorTestosterone/ nandrolone. The NorAndros lack a carbon molecule at the 19th position on the carbon chain. The enzymes that convert the Andro to testosterone will not add the carbon to the 19th position ( they do add a hydrogen molecule ) and without that single carbon atom it will not / cannot become testosterone. The difference between the Andro's and the NorAndro's is the conversion to testosterone or nor testosterone/ nandrolene. Andro converts to testosterone which is the most important hormone in the male body for energy, libido, muscle size and strength. However there are the androgenic (related to the masculine imparting effects) side effects which include hair loss, testicular shrinkage and the conversion of testosterone to estrogen. This last effect is the greatest concern to me personally. Increased levels of estrogen levels increase body fat, lead to possible heart disease, and impart the possibility of female physical characteristics such as enlarged breasts or gynocomastia. Yes, what is known in the gyms as " bitch tits " is a result of high levels of estrogen, resulting from the natural conversion of excess testosterone to estrogen. And excess levels of testosterone will convert to estrogen. The rate of conversion of testosterone to estrogen increases as we age. Nortestosterone provides many / most of the anabolic (muscle building) effects of testosterone without the negative androgenic side effects. Since the NorAndro isomers do not convert to testosterone many of the negative side effects of Andro are eliminated. The NorAndro isomers have many of the same anabolic effects without the androgenic effects. The nor Andros convert to nor-testosterone which has the anabolic effects without the androgenic effects. The NorAndros convert to nortestosterone and nandrolone, which is a marker for the anabolic steroid Deca Durabolin. The Nor's will aid in training without the side effects of hair loss, increased libido or bitch tits. There are supplements that claim to reduce the conversion of testosterone to estrogen. However this is an area of much discussion and I have seen no objective research on this topic. Chrysin is one nutrient that is claimed to stop the conversion. There are vendors that claim the chrystin on the market now is of poor quality. There are prescription medications that do block the testosterone > estrogen conversion. 4 androstendiol and 5 androstendiol 4 androstendiol and 5 androstendiol are so close to identical that selecting one over the other is like flipping a coin. The 4andro seems to be a little more resistant to the estrogen production. 4 Andro converts much quicker to testosterone than Andro and seem to be superior in raising free testosterone levels. The 5 Andro converts to testosterone plus the 5 Andro isomer may have an anabolic effect on its own, without the conversion to testosterone. NorAndro NorAndro converts to nortestosterone / nandrolone not testosterone. The anabolic effects of nandrolone are similar to testosterone. The nandrolone remains attached to the receptor much longer than testosterone and thus will have a longer lasting effect. I have read that they will stay on the receptor site for up to 4 days! The NorAndro will not have the androgenic negative side effects of acne, unusual hair growth or male pattern baldness. NorAndro will not convert to estrogen. Ok, tear me up..
