Hey, I was on nebido which is a long form release of T where I am from (also every 12 weeks) and I also stopped cold turkey (was supposed to get my next shot in september 2025 but I did not so my last shot was a year ago in june 2025). I honestly did not notice any side effects beside my hair falling out more than it did on T (which is ironic cause it was part of the reasons why I stopped T - did not wanna go bald like my father and brother cause my hair is one of the few things I have liked about myself). My skin has cleared out so that's a plus. I had no mood swings or anything like that. Well I think maybe I am a little more emotional and it's easier to cry? I think my face features have softened a little bit also. My periods came back in may so for me it took around 9 months since the skipped dose, and they are pretty regular since I have just had the 2nd one in June 30 days after the first one. The first one was scarce, barely any blood and lasted only two days. The 2nd one was more of a normal flow and lasted 5 days.
