Hello all, I have been lurking on this forum for a few weeks now. A FOAF has just done an A/B extraction using the Marsfold Tek but the acidic ph was 2.4 everything else was the same. He started with 1lb MHRB bought from an online vendor (can I post where?) and ended up with about 5.8g of yellowish crystals. He then recrystalized with virgin Naptha and ended up with mostly white small fluffy crystals..... However, this spice has not smoked like any spice he has used before. It smells the same, it looks the same BUT.... 36mgs did very little...barely threshold. 40mg did not send him anywhere, there were some image flashing, but no kaliediscope patterns, no breakthrough... The after effects were notably strong and lasted longer than usual 55mgs did the same, but the after effects lasted almost an hour.. Was this some bunk Mimosa, maybe a different species? Can this be cleaned up with further recrystalizations, possibly using heptane? My foaf uses a glass bubble type of apparatus, similar to a freebase pipe but with a bent glass bubble vaporizer chamber. It has worked very well for him in the past and he can usually blast off to hyperspace in 1 to 2 tokes @ ~38-50mgs... Any advise I can give to my friendly neighborhood foaf would be much appreciated. Any advise would be greatly appreciated!
