Unfortunately this day in age coke is cut to accommodate crack so its mainly cut with procaine and boric which both convert to freebase/crack hence when vendors show wedinos results that say cocaine only because wedinos don't test for inactive things like boric yet the coke is 90% boric. Its best to preform a chloroform wash to remove the impurities first
The TG stuff is between 10 and 15% just drop 10ml chloroform on a gram them finish with acetone wash you will see but I can get street stuff which is about 60% which is strong af but I like my stuff clean
