Steroid esters, which are nonpolar, are oil-soluble, and are just put into oil based solutions. Steroids without esters are just put into water to be injected, not soluble, and sit as a suspension in the water. Oil based injections are preferred as they last longer and require less injection. After injection, the steroids stay in the body/bloodstream for a couple days. The time varies a lot, as oil based and water based injections last for different times in the bloodstream - esters are dissolved before the rest of the steroid is - and also because some bodies metabolize steroids faster than others. The injections are better for the health than oral steroids, but since they stay in the body for so long, steroid test have an easier time catching steroid users if they are on
