If your doing low dose, keeping it mild then one a week is fine , but when going for the " main event " , on higher dose , then one or twice a month is enough.
To me DMT is like a Ferrari , it's great when pottering around in it , no worry's, , but it's only when you push it to what it's capable of , is when You see it in its true light .
I usually do 25mg on my emesh and I am gone, I would like to go higher but been stuck on this dose a while, I know more would be a greater and longer experience, well so I have read and been told.
I would love to visit more but very cautious of a hyperslap and also and more is MR Fear, I hope to move on from this, even twice a month would be brilliant. More meditation daily and on the day planned to visit just lay out everything, load up and sit with it.
I like your DMT is like a Ferrari expression very very true!
