It might be more effective to just turn them into injectables or sniffables. Some may be irritating to certain tissues also. Why not just try topicals?
Sounds pretty gross bro... plus if you have to take it a few time per day what would you do? Run to the bathroom and plug one in the ass while at work? And what happens if you need to fart and the PH wasn't fully absorbed yet? You'd fart out a big chunk of the PH you tried to stick in there.
I know it will be more bioavailable this route... but you don't know how fast it will be used, so you don't know if you'll have to be plugging these all day long or not like oral pills. Just a thought... i'm out.
