I don't think anyone on this board is experienced enough to use osmotics. They are very tricky to get right. If you fuck up, your blood pressure will shoot through the roof, and you may have big, big probs.
I don't think anyone knows what andreas munzer actually died from. People were saying he was taking like 40 halo a day plus igf1, hgh, drol, and EPO. EPO will increase your red blood cell count, and sometimes this causes a problem, but it makes you lots lots more vascular. Did you guys ever hear about the european olympic runners that were blood doping and they would die, because the RBCs would get caught in a cap, or art or something and they would have a heart attack? The more RBCs the better oxygen, but too many, and your blood can't move!
