TOPIC: Trimix after Filler

Hi, I was told by a Urologist yesterday 2 things that were different than what I've heard before.
1. that you shouldn't have sex for 6-8 weeks after filler.
2. that you shouldn't use trimix/quadmix for 6-8 months after filler.

I have heard you can have sex 1 week after filler all the way to 1 month after the procedure.

Any research info out there? I'm not finding it...just what individuial docs advise.
