Kicks in fast, first day I felt like shit like the flu or something, put on some size fast, burns fat like crazy you will literally piss out fat cells in the morning your piss will be almost brown no matter how much water you drink, sides are kinda harsh, oily skin, back pumps but not as bad as dbol, run out of breath if you try to run any distance.... I stopped taking it cuse the shit makes me crazy, like rage fucking crazy then all depressed and sad...
