I have been doing a transdermal homebrew cycle of 19-nor and 4-ad for about 5 weeks, and a buddy of mine gave me a vial of ref-b for free. My question is that ever since I have started the dbol i have been getting pains on the left side of my chest. Im not sure if its my heart or something, or if its just because I've been lifting much more weight than normally. Any feedback is helpful, and also what is everyone's b.p.m. while they are taking because my resting heart rate is about 90
