never tried that stuff in your picture, i have extensive experience with t3 and t4 though, from what i noticed it doesn't really make you hungry, just kinda makes you feel weak and flat, in terms of t3 anyways. when i take t4 on an empty stomach it exacerbates that empty stomach feeling for me, but not a genuine "hunger" i would say, as in there's no real drive to consume everything you see (the way you get with weed, if you know what i mean), it's just sort of a "man my stomach feels really empty, it would probably be good if i ate something" but it is possible to ignore it. i think in retrospect i'll stick with t4, much easier on the thyroid, etc.
i've also heard of something called "triacana" which apparently was used in the arnold days but can't find anywhere to get it. one of the gh15 suppliers sold it but it was expensive as fuck, and i don't really trust those assholes.
