How do xenohormones work? As their name suggests, they are not real hormones, but compounds foreign (xeno in Greek) to human body, showing the same effects (and sometimes also side effects) as corresponding hormones.
Modified tocopherols and tocotrienols are xenohormones corresponding with anabolic steroid hormones.
It means that they are stimulating the same processes in the human body – like protein synthesis
(anabolic action) or AR receptors stimulation (androgenic action).
Once scientists learned about those effects of modified tocopherols/tocotrienols, they were just a step away from creating more-or-less perfect clones of existing anabolic steroids like testosterone enanthate, nandrolone decanoate, methandienone or trenbolone.
Of course, there are some significant differences. For example, xenoandrogens do not aromatize. They however sometimes show mild estrogenic effects, probably by directly stimulating one of the two estrogen receptors.
While some of those mechanisms are well understood, others are still only vaguely described.
Thanks to the modern technologies like NextGen DNA sampling and SNIP (Single nucleotide polymorphism) detection, the anabolic and androgenic effects as well as some other properties of xenohormones can be identified relatively very quickly in laboratory animals.
In this way, commercial laboratories have been able to develop considerable range of xenohormones very similar to existing anabolic androgenic steroids.
