The LSD study captures the same effect actually. There is no sustained BDNF increase outside the 6 hour window they measured. In fact, it's seems as if the BDNF is entirely eliminated at the end of the 6 hours. From this, I'd guess one wouldn't see a sustained increase in BDNF levels from microdosing either.
