TweetI have used it several times in the last couple years and IMO I am with guns. I am worried about my heart on clen and other stims. I like DNP and feel it can be used safely. Stay hydrated, plenty of antioxidants (a,c,e,coQ10) and some others I cant think of off the top of my head. I know several guys that use 200mg - 250mg a day for 30 days. As with anything we use it has its drawbacks but I have some waiting and will run it again in Jan.
