I don’t know about the OTC ones you have listed, but I want to say on the general topic: don’t get prescription strength appetite stimulants unless you actually have a medical need for them because the side effects can be brutal. Having battled an eating disorder, I’ve been on both Periactin and Megace before at different times. They work very well, at least at first (I found they lost effectiveness over time) but they are only worth it when the alternative is eating so little it’s dangerous because they can really mess with your mood, energy levels, and general health.
