Prohormone 19NorDiol is an estrogen
For years supplements manufacturers sold products like 19NorDiol, a prohormone that converts into nandrolone. If Bush hadn't banned the first generation of prohormones in 2004, the stuff would still be on the market now.
Well.
An article on the active ingredient in 19NorDiol: 4-estrene-3-beta,17-beta-diol and its twin 4-estrene-3-alpha,17-beta-diol.The prohormone you can buy online is always a mixture of these two, whether you get old-fashioned stuff in capsules or in the hip cypionate form. In the body the enzymes 3-beta-HSD and 3-alpha-HSD convert the prohormones into nandrolone. See below.
Nothing new here.
But what do we read in the article on osteoporosis? That researchers have discovered that 19NorDiol mostly behaves as an androgen.
The table below shows how well the different estrens, 4-estrene-3-alpha,17-beta-diol ad 4-estrene-3-beta,17-beta-diol, interact with various steroid receptors. Note also the interaction with the progesterone receptor.
The figure below is also interesting. It shows the effect of a series of hormones – including the estrens – on the uterus in test animals. The effect is reduced by half if the test animals are also given an anti-estrogen (AE). An anti-androgen (AA) inhibits even more, but still – the message is clear.
The precursor-industry fed consumers a hormone that was not only androgenic, but also an active estrogen. Now you know where your gyno came from.
