That is what Biotest's Mag-10 is -- 1-testosterone with an ethylcarbonate ester, which is supposed to improve the oral bioavailability. They don't have any references to data on its effectiveness on their website that I have seen, and other esters as well as ethers have not been particularly good in the pasy, so who knows at this point.
There will soon be other 1-testosterone products (though, I hope the manufacturers use the chemical name and "testosterone" is going to send out all kinds of warning flags to the Man. As usual, I am sure most of them will not be efficacious, but 1-testosterone is a bad mf'r, so the potential is there.
