I for sure enjoy shot day, which one of them is today, ha. I enjoy routines and processes, plus it's a marker for another week down in the journey. A tactile representation of progress. Satisfying.
I also have the paid Shotsy app. It's nice, as I am currently stacking low doses of Tirz and Reta. Keeping track of estimated med levels and injection site rotations is a breeze. I will probably use it to track TRT if I end up on that road, just awaiting lab results for that. But yeah, great app for the GLP-1 users, especially.
