I recently received a shipment of u47700 in the mail. I was using the chemical and experienced very good results. The problem that I worry about is that it's caustic. It is known to irritate and burn tissue, when in mouth or nose. Does this mean since it effects the brain, it also effects it in this caustic way? Since it can cause some temporary damage to your mouth can it cause damage to your brain? or is possibly the part of the chemical in the brain does not act that way and only gives sense of euphoria exc. any info would help as I'm knew to chemistry and ordering products. Thanks a lot and always be safe.
