I have tried tesofensine from a legit source- also capped. You are right to fear the insomnia and the half life is the longest I have ever experienced. I took one in the morning and that ONE dose seemed to last a week, and within that week I definitely struggled to sleep. It requires a well planned sleep stack imo. I took melatonin, lots of magnesium, ashwaganda and passionflower etc. I also tried gaba but I was a little wary of the serotonin syndrome or messing with that (though I have not done enough research to confirm this risk). I also stopped any caffeine, stims, stressing or fighting with significant other, and even playing video games/tv/social media (essentially anything that even mildly released adrenaline) especially later in the day, as the adrenaline would stick around much longer than usual. I found Laxogenin a little helpful with any anxiety. Some mild headaches the first few days but not too bad. Again, this was only with ONE cap, which I chose not to continue daily due to these effects and my lack of preparation for them. Theoretically someone sensitive or frugal could maybe run this once a week and still get benefits.
All that aside, it was a great appetite suppressant, increased my productivity at work, workouts were great and without a crash afterward, and my girl said I was nicer. I lost weight without feeling the usual lethargy that comes from a deficit. And I plan to run it again, when I have a month with no foreseen stressors, prepared food, anti catabolic's, and a sleep and stress stack at the ready. I also had a friend break up the capsule and micro-dose, and he received the same effects, so that might be a easier trial run. If it were me I would pick a good week, take 1/2 or 1/4 the dose to asses tolerance and if you can handle it. This is what I like about the MA version as it is in a dropper, and more easily dosed.
Looking forward to hearing what you think when you do try it. I'm torn.
