19-Norandrostenediol, 19-Norandrostenedione

19-norandrostenediol is a precursor to the steroid nandrolone. This is considered to be one of the safest and most side effect free steroids. It does not convert to DHT, which makes prostate enlargement, acne, and hair loss all much less likely, but it does have some estrogenic side effects. 19-norandrostenediol is superior to 19-norandrostenedione because it has a higher conversion rate to nandrolone and does not directly aromatize as the dione version does. 19-Norandrostenedione is a potent precursor substrate to the anabolic hormone nortestosterone. Through a natural enzymatic reaction, 19-Norandrostenedione is converted to nortestosterone. Nortestosterone is anabolic hormone that possesses a higher anabolic to androgenic ratio than testosterone - its anabolic properties are greater than its androgenic properties. This is a very sought after quality for those who are sensitive to elevated androgens.

19-Norandrostenedione (and its derivative 19-Norandrostenediol) is an androstenedione molecule without any carbon at the 19th position. Without carbon added, norandrostenedione cannot be converted to testosterone. Instead, it is converted to nortestosterone, in other words, nandrolone. Nandrolone is an extremely anabolic substance with a very high anabolic to androgenic ratio and will not convert to estrogen. As a result, users can expect big muscle gains and body fat loss without any of the unwanted negative effects of either androgenic or estrogenic compounds.

Norandrostenediol is the latest addition to the steroidal pro-hormone arsenal that is converted in the body to Nandrolone (which many of you may recognize for its highly "anabolic" properties). Preliminary studies seem to indicate that Norandrostenediol is a better Nandrolone precursor than Norandrostenedione. It acts as a very potent anabolic compound that has strong nutrient partitioning effects that drastically increases lean body mass and decreases body fat stores. It also seems to have anti-estrogenic properties and improves one’s sense of well-being.

Norandrostenedione is another precursor hormone which is also converted by the liver to nandrolone. It is very effective at binding to the body's steroid receptors and will bind tighter and remain attached to the receptors even longer than testosterone.
