I am very glad to have found this place. I find it a bit difficult to explain the Research Chemicals to people who haven't encountered them first-hand. I found Research Chemicals just before THEY swooped in in late 2004. I have recently found that 2c-i is effective, even at very low levels (less than 5 mg). SWIM's friend is less tolerant than SWIM, and tried an amount less than 5 mg (probably 3-3.5 mg). Duration was shorter, visuals were extremely mild, but there was a definite effect, and SWIM's friend said that in many cases, this would be a sufficient amount for her. That was very interesting to SWIM, because I have been researching this for nearly two years, but never thought to administer ultra-low doses. SWIM's standard is 15-20 mg, which provides SWIM with a 6-8 hour ride. I have his Research Chemicals divvied into 5 mg caps, for maximum customization of each person's needs. Again, thanks for having this forum of information! As I have been researching somewhat regularly for over two years, it is hoped that he/she can provide some valuable information as well!
