Did you use absolute ethanol or 95%? I wonder if the small percentage of water in Everclear would have any effect on whether or not the DMT will degrade...

I think I'm going to join in on this little test here, store three even amounts of DMT in 95% ethanol, 99% IPA, and VM&P naptha for a year to determine if DMT is more likely to oxidize in one than the others. I am out of ACS-grade petroleum ether and I wish I had some absolute ethanol, but using Everclear and VM&P will be more applicable because people on the forum are more likely to have access to those/have those around their house.
