Well Erase-Pro (or anything) is not a magic supplement that will give you abs if everything else, particularly diet, isn't 100% in check. You say your diet is "pretty good". It should be "great"... "pretty good" won't cut it. Literally. Do you know what your TDEE is? Do you count calories or macros? It's not enough to simply "not eat junk". I never ate junk for years and I looked in the mirror one day and really didn't like what I saw... and that was because unbeknownst to me I wasn't doing anything right, even though I thought it was enough just to eat good healthy food. It's more complicated than that, and does take quite a bit of effort and hard work. Not that I'm saying you're not putting the effort in, as I'm sure you are, but it's just a case of knowing what areas need to be focused on... and popping a few pills every day isn't going to be the solution I'm afraid... as much as we ALL wish it was lol.
Oh, and I guarantee you don't "lack the ability" to lose your bodyfat, you simply lack the knowledge... that may sound harsh, I don't mean it to be.
