hi can anyone give me any advice on how to tell if or what gear i get is cut with. over last 6months i have had various differnt types, including*Stuff that looked like hardened wet washing powder in mass and broke without use of heaps of force,into tiny little crysallike shards very potent, not much smell tasted like shit very clean high (ingested) no hard core comedown at all really easy on my body. * this stuff was hard as rock was caramel and creamy swirls as if a piece of actual rock like sandstone broke with lot of force into powdery like lumpstook agesto dissolve in hot water some reason this type reminds me of the smell of calamine lotion, foggy high not euphoric with that zoom same come down very flatlined* this stuff looked similar to a dark purple/deep burgundy quartz crystal that hard th break apart not much smell tillyou crush it goes toa shiny crystaline powder almost how jelly powder looks and then it stinks tastes foul too, acidy ok high body goes into damage control doesnt like this shit and very mediocre post comedown. i have ben told that anything that is coming in hard rock form including the 3 above these days is becauseof itscut with msm and to tell by mixing it with boiling water putting in fit as if to use and see if it crystalises back up as it cools,i tried this with the last 2-no more ofthe first typeleft- *-( and dot variousdegrees, 1stayed clearish except for a little sedementy type thing that formed at the tip and floated around, 1 got half crystalised with really long and oddshapedrods someeven part circular, 1 crystalised solid within minutes to an cracked opaque glass look. i dont knowwkat to make of this. also what are theside effects of msm on your body cause i had crystally sharp things coming out ofmy skin that burned when i hot hot and have massacred my skin which is super sensitive,i thought it was fibreglass fibres also my circulation isnt crash hot but my legs, ankles swelled really fast really bad,ive had this before and assume gear related its usually if ive been up for days and had my trotters on oink oink,but not both legs same as usual left was way worse and basically seeing all those sharp crystalls in that fit out on a tissue was like slivers of glass and i freaked thinkin bout it doing that in my gut , kidneys etc so i have this stuff dont want to move any or use any until i know more i wouldnt want to inflict these side effects of mine on anyone even if im a one off i need to know.thanks if i have posted wrong or something let me know as its my first post, thanks.
