I recently received some of both 5-mapb and 6-mapb. I've been doing some reading up.. I hear mixed reports on the 5-mapb. Everyone seems to have good experiences but a lot of them end with severe side effects afterwards.. what about the N-methylation would cause such a drastic increase in side effects? I have not found much info at all about 6-mapb. mostly speculatory threads and maybe 1 experience report from another forum.. I plan to try each one separately at first to get a feel for them.. but I'm always reading about how the Best combo in the world is a mixture of 5/6-apb.. I was never able to get this accomplished so I wonder would it be substantially more dangerous to try a mix of 5/6-Mapb? Is there a risk of Serotonin syndrome or some other dangerous reaction? I also have some 6-apb as well but I am not entirely convinced that this 6-apb is great quality so I am leaving that one alone for time being.
