Starting my first cycle of Thymosin Alpha-1: Any advice on injection frequency?

I finally got my prescription for Thymosin Alpha-1 filled now that the Category 1 reclassification has made things so much easier to source through my local compounding pharmacy. I'm looking to use it primarily for immune support and to help with some lingering inflammation issues I've had since a bad bout of flu last winter. My doctor suggested a starting dose of 1mg, but I'm seeing conflicting info on whether to do it daily or just 2-3 times a week. Does anyone have experience with a specific protocol for general immune modulation? I'm also curious if anyone has stacked this with Selank for stress management—I've heard they play well together, but I want to be careful about overdoing it in my first month. Any tips on injection site comfort would be appreciated too, as I'm still getting used to the SubQ routine.
