I don't doubt that the ester patents claim "higher mg/mL obtained with ester" and "reduced injection pain with ester."
But let us not confuse patents with peer reviewed scintific journals. Patents are written in a highly inclusive format with statements made regardless of experimental basis. This is to protect the invention from taken, scewed slightly, and then re-submitted by another party.
Hydrolysis of the ester occurs and the interphase. And ester length does indeed increase oil solubility of the steroid.. it is for this reason that molecules with longer esters give rise to hormone levels that don't peak as high as short esters and don't return to baseline as fast either.
In other words, I think the pharmacological evolutionary persistance of acetate, prop, enanthate, etc esters is rooted deeper than simple administration vehicle value.
