I took Trimetazidine for about a week at the dose of 20 mg three times a day. I didn't notice anything. No improvement, no side effects. I have stopped taking it.
I tried it. I took it at 35mg (sustained release) for a few days. I got an increase in hormones (thyroid, cortisol & androgens), but it felt a bit artificial (i.e. not necessarily a good thing). Will be trying it again at some point to get some more observations, but I strongly suspect I won't be able to take this long term.
Many thanks for the feedback on this, it's always wise not to ignore the 'false' energy feeling as it can mask so many warnings that your overdoing it.
