Toxicity issues: I can relate to the associative word recall problems, but they were oh-so minor, just enough present that it got me thinking of the 2C-B-Fly had anything to do with it. This happens to me occasionally anyways for no (apparent) reason, so take from that what you will.
Peripheral vasoconstriction was definitely an issue, hands and feet were cold with a bluish tinge, but more centrally there was a feeling of warmth. Damn those fragment sentences.
My friend and I both experienced odd headaches that we suspect were a direct effect of the chemical. This was more notable at 15 mg than at 10 mg.
It was not nearly as potent as we had expected it to be. Both of us felt that 20-25 mg would have been easily tolerable (neither of us is especially sensitive/insensitive to drugs in general), though we both declined to pursue the chemical further due to the extremely likely prospect of that damned funny headache.
So, now, I have a question: does anybody know anything or can anyone offer any speculation as to potency loss of this compound when stored in aqueous solution? a FOAF has about 40 mL of a 1 mg/mL 2cbfly solution laying around and they're wondering if it's still good after nearly a year in water. It has been stored in a canning jar in a dark, cool place.
