Perd, I don't understand how you can say, that you barely could feel 100 mg. One dose of 100 mg of the stuff I have, would blow me away.
I have a very light tolerance to arylcyclohexylamines, if any at all. I do know ketamine and MXE very well, but I never developed any tolerance, because I never abused them or used them on consecutive days, except at festivals. I weigh about 70 kg.
To me, a line of 25-35 mg yield an effect somewere in between light and the low end of common. Looking at Solipsis charts from Erowid, that would make it about as potent as ketamine. But here is my problem, it's not ketamine, it's a totally different Drug. Duration is different, the dose/response curve for sure will be different. And it could never be passed off as ketamine, in my opinion, eventhough they have similarities. Oral bioavailability is also most likely going to be different than ketamine, but I haven't tried it oral yet though.
In the beginning I was trying to guesstimate the potency compared to MXE, and I thought it was maybe 2/3 the potency, then I thought, wait, maybe it's more like 1/2. The thing is, it's pointless to try to compare the potency in quarters or percentages, because as I already said; it's a different drug. Similar, yes, but also different. I think this comparing potency has to stop, because it's too difficult to gauge. We need to make a totally new dosage chart for MXM over time.
30 mg for sure is a good light starting dose, insufflatted, for anyone without tolerance. It comes on pretty quick, so it's really easy to top up with more. Even though that dose wasn't as strong as a similar dose of MXE, I was still satisfied and didn't need to take more right away. So in the end, my doses actually came out same as with MXE. But not fucking me up more than I still was able to go out shopping.
What we can say, is that it is certainly less potent and has a shorter duration than MXE, but not by how much. In my humble opinion it's pointless to talk about.
I'm with Boida, in that its potency shouldn't be underestimated, because the effects are more subtle than MXE, but it surely has the power to be just as wonky. In the doses I've taken, it surely doesn't have the same sledgehammer in your face effects MXE can have, but it can still twist your world. Some hard core MXE freaks are going to be dissapointed with this one, but it deserves respect, both for being a beautiful chem, as well as surely having the ability to tear a first timers reality a new asshole. It's not NENK or 2-MeO-ketamine, for sure.
Solipsis. It doesn't seem that ketamine share the same SAR as the other arylcyclohexylamines we know, because if it did, NENK would have been a winner. There's an interesting piece of information in that fact.
