For pure xtals i only use the e-mesh.
I don´t know about 5mg knocking your head off. There won´t be much effect unless that person
was talking about 5 Meo Dmt.
If you have taken a large hit of enhanced leaf in your plenty you know what to expect.
The process is just very effective.
And while harmalas make it a bit slower they also increase the power of the spice.
Give it a try and start low.
Some people just never really got their smoking technique right and once they use the e- mesh
or Gvg or whatever works for them they are very surprised by the power.
My only extremly uncomfortable experience was with the e-mesh and no harmalas.
It is not expensive and alot of fun.
Have a gud one
Hope you like it
Psychedelic drugs don´t change you, they don´t change your character,
unless you want to be changed. They enable change. They can´t impose it.
