well for what i have learn here SD is a great pro-hormone along with phera-plex. I have a bottle of Sd right now and am planing on getting some Phera-plex soon. I was wondering is their any other Pro-hormones out their that you guys know of that work like these two? I thought i heard their was one that might be like tren? Well i was just wondering if their was any Pro-H that could compare to Sd and PP or come close?
