Wanted to do a full 4 weeks, but I had to stop at 3 1/2. Back pumps have become unbearable. These are the only sides I've experienced. Taurine and bananas did nothing for these. I started at 215lbs and I weighed myself today at 230. My strength on all lifts are way up. Considering I do not really watch my diet I'm really pleased with my results. My muscles look fuller and leaner. PCT includes Nolva, Clomid, Giant ATD, Fenugreek and DHEA. Planning on running a E-max cycle later on during the winter. I'm interested in seeing how this compares to SD.
