I've heard similar accounts of MDMA losing effectiveness with folks who have used regularly for extended periods of time. I haven't experienced it myself but I try to wait at least 8-12 weeks between uses. I have a theory that for many people it comes down to the highly variable quality of what you get on the street. I buy all my stuff on the dark net and test it, and after figuring out a couple of other variables that have a big effect on me (mainly: timing of food consumption. I fast minimum 5 hours before a roll) I have had very consistent experiences. But the quality issue would certainly not be at play with the Shulgins so I wonder if there's something to the long term effectiveness stories.
