SWIM sliced the 14" SP cactus into 3" sections, and cut the stars lengthwise into wedges. SWIM then peeled and cored the wedges, and put them into a bowl and put it into the freezer overnight. In the morning, the thaw left a fairly large quantity of liquid in the bowl. The liquid was drained and set aside. SWIM squeezed the wedges to wring the remaining liquid from the cactus and put the chunks into the blender. The mush was then put into a pot with some lemon juice and a small bottle of purified water. The mix was slowly simmered for aprox. 2 hours. SWIM then performed the T-shirt in the blender trick (as seen in the #5 method in the Erowid cactus vault) to wring out the water. The two liquids were then added together. SWIM only drank one third of the liquid (because this was an unknown substance and an unknown potentcy). The experience was comfortable, but definitely present. It felt like one-half to three-quarters of a dose. Definitely successful. It has a little bit of the alkaloid tight jaw/low voltage to the lower wisdom teeth feeling, but not bad. Energized at the core, but totally lazy. No visuals at this strength, but real euphoric body high. Twice this dose should be incredible. All of the liquid would probably be out of the comfort zone.
