I would suggest pill form. If you think about it, winny usually comes 25mgs a pill, take one in the morning, one later on in the later afternoon. If you have to pin, you're going to pin at least once a day, sometimes twice a day depending on the dosage. Also, most winny is water based, so never inject it with your oil based compounds or you could get a nasty abscess. Btw, most people just end up drinking their winny from the bottle and it costs more. just my .02
