got some of Good_old_hive's batch from december. to me it feels like a 7-8/10, pretty good but not as good as CapeCrusader's. have had it lab tested and it came back as: 75% 4-mmc 14% mephedrone 11% 4-mpbp
keep in mind this was done on cheaper spectrography equipment and i'm not sure about the experience of the technician. i thought 4-mmc and mephedrone were the same thing so that might just be a lab error. not sure what 4-mpbp is but presumably some sort of unreacted precursor or synthesis byproduct.
i've found mephedrone to be extremely subjective before, seems to vary from batch to batch even if the purity is high. perhaps its like k where the isomer ratio makes a big difference? or different impurities are causing a pronounced effect? or its all just in my head?
regardless will be ordering from CC in future. hive is definitely a solid vendor, but his product isn't what i remember meph being like and his country of origin is potentially heaty to order from imo.
Mephedrone is 4-MMC. Could you ask the lab about this?
