i just did a toluene pull on 50g of exhausted MHRB and ended up with a little bit of yellow oil which doesnt seem like it can dry anymore. i guess most of the dmt was already pulled out with the naphtha. maybe a hot toluene would yield a bit more, im not sure.. but i probably wont be pulling any more from that batch.. i have a 200g extraction going now and plan to do a few heated toluene pulls on that
