if you're just coming off a cycle of Epi and you're running your PCT I'm not sure I'd be so eager to mess w JW. nobody really knows how or what it does and some users complain that it causes further shut down. definitely if you're ending a heavy duty cycle you must give yourself enough time off to fully recuperate. your body is not ready to take on another cycle directly after PCT. usually time on + PCT = time off, so I'd give it a good while before running JW.
I don't have much experience with Jungle Warfare, but from ALRI's writeup it's supposed to encourage lipolysis. So I guess you COULD use it for fat burning. However, I would not think about taking it until a good while after your cycle is done. Just diet down meanwhile.
