Tesofensine is genuinely interesting, it is basically a snri type antidepressant drug, except it blocks reuptake of dopamine as well as noradrenaline and serotonin. Developed originally as an antidepressant, and works in rodents but never tested for that in humans, and got sidetracked as a weight loss drug when they noticed it caused weight loss in rodents. It has had human clinical trials for weight loss showing 9% weight loss over a year, making it one of the very few agents that are not GLP's that actually work. I think they also did a study with it combined with a beta blocker to reduce sympathetic nervous system effects as well.
It does have a very long half life of about a week, and almost every person trying it that I have seen online, has run into issues with it accumulating over time and causing delayed adverse effects because of this, especially if using daily dosing, and many ended up using tiny or weekly doses instead. Anxiety and insomnia are the most common issues if I remember correctly.
