Yeah I always filter mine — it's cheap peace of mind and makes me feel a lot better about using them over an extended period.

I've done a pretty thorough search through as a whole and picked up quite a bit of info, but I want to hear what people are actually doing in practice. My current plan is to take Zyrtec about 30 minutes before injecting and apply some Benadryl cream directly on the injection site. I also came across mentions of Flonase being part of some people's approach. What's the full protocol you're running? Looking for something real and tested, not just theoretical. Appreciate any input!
