I am currently taking Imactamin Premium One.

Actually, I've tried various medications(?) and supplements(?), but I don't really feel any significant effects.

It's just that I can't feel it, but it might actually be helpful to the body.

Anyway, I don't consistently buy and take a specific product. I try different things by changing various options.

Eat only one at a time, and since you buy at least one, you'll be able to use it for more than a month, so you'll probably end up using the product from the busy month a bit more.

Currently, I am taking Daewoong Pharmaceutical's Impetamin, but I think I need to keep an eye on it.
