Dosages are only one aspect of all this. Without running a test to isolate everything contained in the Raw Powder, the tests show how much "crap" is in there.
Also, if you get some high grade Raw, you'll just be over dosed. Truly accurate dosages are impossible without knowing potency.
I can really only compare it to illegal drugs and their variations. Someone could sell you a drug that's only 50% of what we actual want. Tryptamines can pretty easy to play with. A crystalline substance that supposed to be a tryptamines can be ran through a couple steps and find out its cut.
If you can brew a RAW you can run though a dehydrator, rinse it and do a melting point check.
Coke on the street I may just be doing for a night. and poisons are short term. A 12-16 wk time frame jabbing things directly into our body is different.
We cant dose what we dont know.
