Im currently taking Phera Plex, im only a couple of days in and was thinking about throwing in some clen at 120mcgs running the clen for 10 weeks total. At week 4 im going to up the dose to 160, then to 180 in week 5 through 10. Is clen going to hinder the effects of Phera Plex in anyway?? I know clen can sometimes effect AS results. Ive used clen before several times and love it, i take benedryl ever 3 weeks to keep results up.
