I recommend starting at 70mg. 110mg is right down the rabbit hole for me. Higher doses made me panic and thought I was going to die. Give it at least an hour before considering redosing. Things get very very crazy at 110mg, and watch you alcohol consumption. Stick to a beer or two, no more. It's definitely a fascinating compound though. Just be careful people, it's a hell of a trip at the right dosage. Don't eyeball, get some sensitive scales. I recommend these:
Smart Weigh GEM20 High Precision Digital Milligram Scale 20 x 0.001g.
£20.00 from amazon. They are exellent.
Oh yeah, the above is oral dosage, mixed with juice or water, doesn't really matter. I heard juice with citric acid is good ie. orange juice, cranberry, lemon juice etc. It can be corrosive if you let the raw powder sit in your mouth, and snorting is pretty useless and gives a dull ache which lasts for ages.
Peace.
After reading through much of the thread I was surprised at how many people have experienced long on-set times, ie. hours and hours. I have done MXP many times and the effects always started to kick in around 45 minutes, peaking within 1.5 hours. Please disregard my '1 hour' resdose time as it obviously affects people in drastically different ways. I would still suggest suggest sticking to more that 110 mg per night though, total. Perhaps this is due in part to the different vendor's suppliers, ie, the composition of the substance.
