it goes through the liver, yes... but bolus dose, no... winny is very painful to inject, I would imagine it being worse subq, but never tried.. might ask heavy that q..oil based winny would hurt less, no real benefit cause precontest you want to limit oils(and winny is more potent orally)...maybe for the people that cant handle the pain of water winny(of course that pretty much defeats the purpose of not taking winny tabs precomp, since oil is going to not help with the 'drying' effect as much.. might as well eat it at that point
