I imagine most of you all have seen one of these by now. I won’t list the seller as l don’t want to inadvertently break rules. Can google it. This thing is a game changer for me. Absolutely painless, fast, and most important in my case, allows for another person to (less stressfully) administer your shots for you. My wife is far more comfortable handling this than jamming an IM syringe as we all normally do. It’s a bit pricey but man so worth it.
