1. What is it and where does it come from?
19-Norandrostenedione is basically an androstene molecule with a carbon atom missing in the 19th position. I know, I know you’d have to be a chemistry major to figure that out. Well, to save you the trouble it’s basically this: 19-norandrostenedione is converted by an enzyme (17-beta hydroxysteroid dehydrogenase) into nandrolone in the body’s liver.
So, in essence, 19-norandrostenedione does not convert directly to testosterone as Invalid Link Removed and Invalid Link Removed do. Instead it converts directly to nandrolone, which is moderately anabolic. Anabolic properties can help you gain muscle quick. High quality 19-norandrostenedione supplement is available from Bodybuilding.com.
2. What does it do and what scientific studies give evidence to support this?Working much like its cousin, testosterone, 19-norandrostenedione studies show that 19-norandrostene may be even better than any other legal testosterone precursor because it does not carry the same side effects as more highly anabolic hormones. Some of the benefits of supplementing with 19-norandrostenedione include avoiding the effects of DHT problems (male pattern balding and prostate enlargement). This is great news for those who want the muscle gains without the hormonal side effects!!! This is because of the conversion to nandrolone instead of testosterone directly. Also, since 19-norandrostenedione uses the same enzyme to convert as androstenedione, they work very well together which conserves your body’s enzyme use and maximizes your hormonal conversion efficiency. Studies conducted on nandrolone show that it is highly efficient compared to testosterone because it attaches to steroid receptors easier and stays attached longer. The conversion rate (to testosterone effects) is 5.61%, the same as androstenedione, but less than pure testosterone (illegal). So, the trade-offs are: getting a little less anabolic steroid, 19-norandrostendione, but still getting awesome results with a much much lower chance of side effects such as DHT problems, as compared to direct precursor
