Those aids sound good. I would have automatically suggested caffeine and ALCAR but you already know about them.
Yeah, I heard that intermittent fasting is good for weight loss but I'm not sure if it's simply from the reduced caloric intake or if it has metabolic benefits.
In Canada, Ephedrine is available over the counter and very cheap, like $5 for 50 tablets of 8 mg each. It's used for short-term weight loss. Check to see if it's available in Finland.
Yohimbine might also aid in weight loss but it seems like there isn't much evidence to back it up.
