Methyldienolone is an anabolic steroid that was
researched in the early 1960’s, but never sold as a prescription drug. It is a nandrolone-based compound, modified to be orally active and to have greatly increased anabolic properties. Methyldienolone is a close chemical cousin of methyltrienolone, one of the strongest steroids profiled in this reference. Methyldienolone is not quite as potent, however it remains quite strong next to most commercial agents. Animal tests find it to be 5 times more potent than Dianabol, 10 times more potent than methyltestosterone, and 13 times more potent than Primobolan® on a milligram for milligram basis. Although the real world relevance of these values may be questionable, methyldienolone is well favored by bodybuilders for its ability to promote lean muscle gains with minimal side effects.
