Summary
2C-T-4 has a slow onset lasting 30-120 minutes, with users sometimes experiencing initial anxiety during the come-up phase. Wait at least 3 hours before considering re-dosing. The substance produces moderate body load including nausea, muscle tension, and vasoconstriction.
Perspectives
“Visual effects set in at about two hours. There was much color enhancement, particularly of green, and some flowing of colors. The bright impressionistic picture of the little girl, in the bathroom, was particularly good for the visuals to take over, especially when I was concentrating on urinating. The shadows in the large picture above the fireplace would change constantly. I could not either control or turn off these effects during the middle period (3–6 hours). From the physical point of view, something early in the experience simply didn’t feel right. Both my lower legs tended to fall asleep, and this seemed to spread to my hands and lower arms. It was uncomfortable and although I was apprehensive at first it didn’t get any worse with time so I ignored it. This is not one my favorite materials, and it takes too long to wear off. If I were to do it again I would settle for 4 or 5 milligrams. It may well cut out the extremity problem amd still allow for a pleasant experience.”
