I'd highly recommend everyone to test all of your substances before ingesting with reagent tests (common sense). A "taste" test is not a proper way to discern commonalities. Also if a human is on medications like SSRI's or prescribed stimulates then any recreational substance will be extremely hindered.Okay guys id say this guys great! Opsec 10/10, customer service 11/10, quality: from 1-10 my readings of the rainbow m was maybe 5. Almost like another reading was mixed into the mag i ordered. I dont have a tolerance to this. All ik that my past with this mag i has authentic reactions. Other than that, my favorite vendor because ik hell make this right! I hope so cuz the rainbow tasted like salt not sour
