Clyclo dextrins are sugar molecules that are bonded together in such a way that they form a perfect sphere. If you put a steroid inside the sphere you then have the steroid hidden within a hydrophilic carrier. I suppose you think that only hydrophilic compounds can be shot sc, however there is no reason for this to be true.

BTW the test finally hit me after nearly a month of SC shots... I suppose the release rate of 100mg of test from a sc shot is very slow... Probably if I was shooting greater amounts of steroid I would have felt it sooner
