Umm... i think YOU need to do more research. Stanozolol is NOT water soluble. Its not really oil soluble either. Why do you think it seperates into white powder, and water, when you leave it sitting around? That is also the perpose of solvents for oil based injectables. If you just toss some winny in some oil, it wont disolve(not disolve=insoluble,) you have to disolve it in some form of alcohol or ether, or what-not, and then you suspend the hormone laced solvent in the oil.
For those interested in the numbers, Stanozolol is soluble 1:41 alcohol; 1:74
chloroform; 1:370 ether; soluble in dimethylformamide; slightly soluble in acetone and ethyl acetate.
(water and fat/oil are not listed for a reason) =P
