i have used the 2mg u.s. pharm winstrol (had to eat a bunch of em) and quality vet (circa 2001) inject. boy that shit made me hooorny as hell. it cut me up and i gained quality muscle, very keep-able but last time fucked up my liver values and i lost some hair. and yes i was doing peripherals and it happened anyway. its gooood shit when stacked with test but obviously disagrees with me. as far as a difference between oral and inject i personally couldnt tell the difference but as holy ghost stated im sure inject is more bioavailable.
