Outside of the fun/excitement of trying something different, whats the big deal? there are dozens of different ph/designers/steroids out there, i'm sure that there is one that would meet your needs.
Well, anything can be improved, so why not improve actual PHs?
For example: My favorite PH (due its very, very low sides) is H-Drol (4-chloro-methyl-testosterone), but even that PH has its risk (its methylated, so its hepatoxics and the methylation could increase AR affinity, so there is a posibility to aggravate hairloss). But, why not make an un-methyled version of HDrol (for example, an acetate version of HD)??
I'm not a "chem", but i think acetate can improve oral absorption, like methylation, but its not hepatoxic and not increase AR affinity, so dont aggravate hairloss.
Thats only an example, and maybe i'm wrong with 4-chloro-testosterone-acetate (iīm not a chem), but anyway i think probably there is a lot of interesting new compounds (or modified compounds) "waiting" to be developed (and a lot of people waiting to buy it).
