I once tried to mix HGH (water soluble) with Test E (oil soluble). My Einstein brain was thinking I could kill two birds with one shot, right? Well, it was a mess. The water soluble HGH did not dissolve in oil at all. The whole concoction was a great big ball of mush. gixxerboy1 makes a good observation. I wonder how they dissolve the water soluble adex into oil.
