Gaining

Are their tablets that I can take to increase my appetite?
I seem to not be hungry when eating so I end up eating less than I want to.

You could take some edibles. Not the same thing, but if you get some indica it can increase your appetite a lot.

There's many appetite stimulants on amazon and wg stuff, usually for body builders but if avoid the nutrient ones and just the appetite stuff then it should work, I also buy bulking powder cos it's v v high cal and cam mix with other stuff to get 4k in 1 shake
