So I've ran out of Bayer primo after six weeks in to my 20 week cycle of 200mg EOD (600mg/wk) and my only trustworthy source will be out for another two weeks. I have oral winstrol which i was holding to finish my cycle with 4 weeks of oral winstrol at 40mg ED. As a backup I will start my winstrol oral cycle now for four weeks and then resume my primo. Will that screw everything up? Any suggestions. I can also get NPP 100 right away will that make more sense to use in the meantime. Or am I totally screwed?
