medium experiences..maybe 15-20. Depends on the seeds though. I think 3-4 seeds with caapi extract is a powerful trip that lasts around anhour, sometimes more, with a strong peak for about 10-15 minutes..thats the seeds I have anyway..so with the changa I made with 40 seeds I got like 10 good strong doses..but then again I was only using 2 iso pulls..and I am sure I was not getting all the bufo out.
