deca lasts forever in your blood
you CANT use it when youre only cycling and want to recover afterwards, simple as that.
just forget about deca and EQ.
if you wanna use nandrolone then use NPP.
and imo shutdown is shutdown. doesnt matter if its 200mg or 1000mg. it probably does matter how long youre shut down though. so shorter high dosed cycles would be "better". however i consider PCTing and cycling a retarded concept, so so much for that
