Did you have any luck with this?
Yes I got it from a Chinese supplier in 2024, but ended up not using it for very long. I still have a bunch of it that I don't need since I was able to heal my serotonin sensitivity with supervised ketamine treatments for TRD. The downstream neurotrophic effects was just what my brain needed to repair or bypass the damage. I was able to gradually increase my protein to a high level until serotonin symptoms vanished entirely.
Other factors that I believed helped:
Tianeptine sodium/sulfate - good supplemental neuroplastic and mood/anxiety support, but careful not to become dependent on (I did for a while but was able to reduce and now just use as needed)
Replacing chronic high dose antipsychotics (10 years) with Mirtazapine over the course of just a few weeks - I believe Seroquel was keeping my brain sick and increasing long-term risks.
Memantine - helpful for a while but a bit dulling to take all the time
Numerous supplements such as Magnesium L-threonate
Recent:
NSI-189 - started a couple months ago, very good neurotrophic that has continued healing and increases stress resiliance.
BPC-157 - started about a month ago, good body healing/workout recovery effects and apparently is protective against serotonin syndrome by inhibiting 5-HT2A.
ACD-856 - a few days ago - another neurotrophic - so far so good
