Has anyone here with the appropriate apparatus ever tested to see how much actual N,N,DMT is in their extraction result using different teks? Or is there literature anywhere on the interweb? I remember seeing a DEA report (I think) on DMT in MHRB and purity was something like 3% or 30%?

Even a rough approximation would be interesting to know... i.e. 20% of result was DMT for Tek 'x', or 90% was DMT for Tek 'y'.

Do you mean appropriate apparatus such as a scale?

Folks here note the weight of extracted spice from the starting plant material all the time. Or do i misunderstand what you're wanting to know?

When starting with mimosa bark the members of the Nexus are reporting 1%-2% extracted spice from the starting material's original weight.

EDIT: I should say that the 1%-2% is the desirable range; certainely possible to get less, ha. And more total spice collected if it is "jimjam" and not just attempts at cleaned up N, N-DMT.

I presume you are asking about N,N-DMT content in the mimosa extract. DEA got 0.8% per weight. The numbers you mentioned (30%) were for a methanol(alcohols are very unselective) extraction.

Burnt, a fellow member, tested some extract. Check "Advanced chemistry topic".
