that's not so bad....but that greatly increases the chances of spewing it all back up....but that inpaticular chemical isn't really harmful, i wo uldn't recommend it tho...i've heard of very few people getting to keep it down wtih that chemical, and with that inpaticular bottle...one isn't going to do much, you need atleast i think 7.5mg/kg of body weight to reach the third platuea (most strived for platuea it's the one people actually start tripping on) and as it stands with that bottle you are getting 3.37 mgs/kg so that's first plateau maybe the second not sure on that. to get you 7.5/kg you need to take atleast 525 mg total or about 2 1/3 bottle. so i think you'd be better off getting one with a higher ratio of dxm per tsp and without the other shit in it....cuz right now you stand a very high chance at puking, way higher than tripping atleast..and if you do get something stronger that estimate drops drasticly so don't go taking that much .....
