So the yeilds swim has been getting from a/b extraction have not been that great over the last few months, only 200mg to 100g mhrb. Any one else have the same, or is every one else that gets from the Netherlands has great yields an I happen to unfortunate. q21 has always been good with other closed down distrbutors of mhrb.

It's because the Netherlands is below sea level; chemistry just doesn't work right there.

Well everything seems to have sorted its self out Im back to 500-600mg per 100g mhrb, once again a happy traveler

Is the bark from a reputable supplier? How many boils are you doing in the acid step? How many pulls are you doing, with what amounts of solvent? How are you retrieving your dmt from the solvent? How do you mix the solvent and the bark?

500mg per 100g bark is still too little imo

Tek 2 is being used here all is followed directly.. https://wiki.dmt-nexus.m.../Lime_A/B_Extraction_Tek

3 pulls 1 every 10 min and a final 24 hours later. Not so sure on the supplier..http://mhrb-shop.nl/index.php?route=common/home
Its the only available choice for the next month for this part of the UK that im aware of.
