Ive been experimenting lately w/Carb up days utilizing GDA - specifically Citrilene (Hydroxy Citric Acid = HCA). Comparatively, I really feel more Pumped The day after than without it. Also, I think it really helps if your a bit insulin-resistant (me) - Im dosing at about 375mg Standardized 30min before and again immediately after- seems to be really benefitial. Q: Are there cheaper but better Supps to help in Maximizing Carb->Muscle shuttle? Ive tried others like Vanadyl Sulfate, Chromium Picolinate but HCA seems to be the most effective. Should I just stick to this? Would the effectiveness diminish in time re: Adaptation/Dependence to HCA for Shuttling Glucose into Muscle cells? Would this make me more Insulin resistant in the long run? I also use ECA during Cardio Days LC days
