Estrogenic Activity low
Progestational Activity high
Ethylestrenol is an oral anabolic steroid derived from nandrolone. As is typical for many 19-nor steroids, this agent exhibits far greater anabolic properties than androgenic, is only weakly estrogenic and is strongly progestational Structurally, ethylestrenol most closely resembles Nilevar (norethandrolonel. The two difter only by the absence of an oxygen atom at the position of ethylestrenol, and in the body ethylestrenol actually has a notable affinity to convert to norethandrolone’ This path of metabolism is responsible for much of the anabolic androgenic, and estrogenic activity we see with this compound, and in most regards ethylestrenol can be viewed as a pro-drug to norethandrolone. Although ethylestrenol is strongly anabolic relative to its androgenicity, athletes generally find this steroid to be extremely weak. The level of muscle growth obtained with this steroid is generally much less noticeable than that expected with either Nilevar or Deca-Durabolin and its considerably less effective than both stanozolol and Oxandrolone on a milligram for milligram basis.
