It's possible but not practical at times. Most winstrol needs wider needles for injection as the particles in it are big (unless you got the micronized kind). This in turn will of course cause more painful injections cause of the damage done to muscle using bigger needles. No problem with a glute that is sore but quads, delts, bi's, tri's are not that fun when injected with big needles. But some of you guys have an insane threshold for pain. I'll keep my 23's and 25's thank u.
