Anabolic steroid alternatives Part 2

What are steroid alternatives?
19-norandrostenedione is the nandrolone equivalent of androstenedione. It is an efficient precursor to its active steroid form, and overall is considered nothing short of a well-proven anabolic. Although like androstenedione this hormone is open to estrogen conversion in its initial state, the tendency for 19-nor steroids to interact with the necessary enzyme is very low. We therefore see very few reported problems with water/fat retention and gynecomastia, even when this supplement is taken in heavier cycles. Most users report a solid gain of muscle mass, typically with an accompanying loss of body fat and increased visibility.

19-nor 4-androstenediol:
Like 4-androstenediol, this prohormone utilizes a more active enzyme in its biotransformation to the steroid nandrolone. It is therefore slightly more potent in comparison to 19-norandrostenedione, however both of these two nandrolone precursors are considered solidly effective anabolics. Only those extremely sensitive to estrogen or using unusually high amounts will likely ever notice a difference in estrogen conversion rates, although technically this prohormone would be more suitable in this regard as it avoids any possible direct path of conversion (the same trait noted with 4-androstenediol).

19-nor 5-androstenediol:
This prohormone is a 19-nor form of 5-androstenediol. While we don't have much to report about 5-androstenediol, there is even less to report about this compound. Its conversion rate to nandrolone is low, and there likewise seems to be little in terms of positive feedback. It seems to be more the product of a clear manufacturing opportunity than of research and successful application. Some may find a use for this compound, but it is clearly not the efficient nandrolone precursor we see in 19-nor 4-androstenediol.
