my first two experiences, sublingual and nasal, respectively, with 30mg were quite strong. I, have used MXE maybe 5 or 6 times in total, spread in 10 months approximately, so tolerance shouldnt have been stabilished. However, my last try with 30mg oral was quite weak! I felt next to nothing, so I am trying to figure what happened.
I thought maybe it degraded, but A quick research in BL tells me its pretty stable. I also dont think tolerance was significative (although I took 60mg of MXM one week before that).
I remember the only time that I took it nasally was quite nice! I was a more social setting and I really didnt notice a big difference, but I recognize I dont have enough experience to conclude that...
BTW, the product i had was off-white, sandy, slightly bitter/salty.
