Congrats on starting T brother! Ofc I can’t speak for everyone but I know I personally didn’t feel more congested after starting.. it could be a cold but I also wouldn’t be surprised if something like that could be a symptom of starting a surplus of hormones that aren’t usually there. I also do injections so idk if the ingestion is different in a way that wouldn’t effect my sinuses? IDK HAH but at least it shouldn’t be anything to really worry about. Hope you get bothered less by the boogers either way
