Testosterone shots must be done on a regular basis. Yet, many FtM’s miss the day of their injection.Testo Memo allows transmen (transgender, transsexuals, FtX, etc.) to no longer forget the day of their testosterone injection !You just need to enter the latest day on which you did your shot and the interval (in days) between two shots. You will receive a notification a few days before your next shot. Once this is done, the date of your next shot will be computed for you!
