I want to try NYC. I make my own ECA because it is alot cheaper. I found some yohimbe hcl 2.7mg per cap. Is there difference between norephedrine and ephedrine? I thought the idea was to come off ephedrine so the receptors can upregulate. I plan on using clen 2wks on 2 wks off for the summer and need something to fill the off weeks. Any help greatly appreciated.
