What's the point? 17-alkylation will likely make it more androgenic not to mention liver toxic. It may make it more anabolic or it may make it less going by the trends I see in other known anabolics. 17-Alkylation will also render this compound just as illegal as any other AS so even that benifit of 1-test will not be possible.
1-test is already a potent androgen and several people have reported hairloss. Make it even more androgenic by 17-alkylating it and goodbye hair. Without some kind of data showing a dramatic increase in anabolism, I would shun this compound like the plague.
