A bit ago I purchased some 4 aco dmt from a popular vendor that recently began stocking it. When it finally came I noticed that it was a tan powder. I've sampled it two times since, and both times I've gotten worrying symptoms. The first time things went well until some strange chest pains started happening. Throughout the experience I also had an increased heart rate, about 120 bmp. I liked the experience overall though, and decided to give it anpother try about a month later.
This second time I plugged it. The chest pains happened again this time and were even stronger than before. My heart rate increased to 130 on average also. I had a stethoscope on hand this time and listen to my heart. I noticed that my heart was beating very irregularly, skipping beats and changing pace about 10 times a minute. I called my girlfriend in to check, thinking it could just be my mind playing tricks on me and she also heard the irregular beating and became very concerned. The chest pains finally dissapated about 6 hours after I plugged it, but it was about 10 hours until I slept.
I trust this vendor a lot, I've done bussiness with them a number of times with no problems in quality, but this makes me wonder if there is some impurity that could be in the tan powder that would cause such weird heart problems. I've seen the tan powder mentioned as being less desireable in a few threads, but never knew specifically why. Has anyone else had chest pains when they've taken it before?
Also, the dosages were 25 oral the first time, and 15 plugged the second time. It seemed considerably weaker than reports I had read also.
