6 weeks then 10 weeks between rolls – would you do both or wait?

Did MDMA on 2 days of a 3-day festival, 17–19 July. Got a rave 30 August and another 5 November.

I know the usual 3-month rule and know there's no magic completely safe gap.

Was thinking 120mg MDMA then 15mg 2C-B powder later at both rather than redosing MDMA. All gear is tested.

That would be about 6 weeks from the festival to August, then 9/10 weeks until November. After that I wouldn't be doing MDMA again until a planned event next May, so a decent break afterwards.

Would you roll at both, or just do 2C-B in August and save the MDMA for November?

Also got a couple of weeks until the August rave. Anything actually worth taking supplement-wise beforehand? Sleep, decent diet etc is a given, just wondering if there's anything people genuinely rate rather than bro science.
