Quick details

What is Norandrostenedione?

An illicit hormone, Nandrolone diketone can be metabolized by the body and converted into synthetic metabolic steroid Nandrolone. According to the news, some athletes try to gain a competitive advantage by using illicit use of norradodione and other hormones.

Over the past few years, hormone supplements have been to the general public to promote. Supplemental manufacturers often claim that the use of hormones may increase testosterone, increase muscle strength and quality, reduce body fat, enhance mood, improve sexual performance. However, most hormonal studies contradict these claims. In addition, many hormone supplements are contaminated with non-synthetic metabolic androgen steroids, not included in the list of ingredients.

Norandrostenedione

Norandrostenedione Descriptions:

19-Norandrostenedione (4-estrene-3,17-dione, NOR) is a precursor of the anabolic steroid nandrolone. Until 2005 19-Norandrostenedione was available without prescription in United States, where it was marketed as a prohormone, but it is now classified as a Schedule III drug. It is also banned from use in many sports, including the Olympic Games, under the World Anti-Doping Code.19-Norandrostenedione is readily metabolized to nandrolone after oral administration, but its potency to transactivate the androgen receptor dependent reporter gene expression is 10 times lower as compared todihydrotestosterone (DHT).

Norandrostenedione Applications:

Scientific studies have shown that oral administration of 19-norandrostenedione is "a very ineffective strategy for stimulating skeletal muscle mass increases but may be associated with side effects".

In vivo experiments in castrated rats demonstrated that subcutaneous treatment with 19-norandrostenedione resulted only in a stimulation of the weight of the levator ani muscle, while the prostate and seminal vesicle weights remained completely unaffected. In contrast to its metabolite nandrolone, 19-norandrostenedione highly selectively stimulates the growth of the skeletal muscles but has only weak androgenic properties.

In the early 2000s, contamination of androstenedione products with traces of 19-norandrostenedione caused false positives for doping tests for nandrolone because 19-norandrosterone is a metabolite of both nandrolone and 19-norandrostenedione. In a randomized controlled trial trace contamination of androstenedione with 19-norandrostenedione was sufficient for users of androstendione to test positive for nandrolone.This detail became less relevant after 19-norandrostenedione and androstenedione were banned by major sporting bodies.
