Were your doctors concerned about your done density when your testosterone was low for so long?
For those who are wondering, Restandol is testosterone undecanoate for oral use. It's not yet approved for use in the U.S., but it seems as though the process is underway.
Liver toxicity is a concern with some oral anabolic steroids, but not testosterone undecanoate:
Instead, Andriol is an esterified form of Testosterone (Testosterone Undecanoate), whereby it is affixed to an extremely long fatty acid chain ester. Research has demonstrated that when Andriol is consumed (especially in the presence of dietary fats), the high lipophilic nature of it allows at least partial absorption via the bodyís lymphatic system through the gastrointestinal tract. Although Andriol is not liver toxic at all, there are some disadvantages to its nature. Because it relies on fat solubility to be absorbed in the body, research has shown that Androlís oral bioavailability is around 7%.https://www.steroidal.com/steroid-profiles/andriol/
It may be analogous to transdermal testosterone, in that absorption and efficacy may be good for some, but not others.
