I love supporting Alp and I support Tucker, I just don’t care much for the product. I like the idea of having cleaner, healthier alternatives, but not when it stains my mouth and leaves residue behind while I’m at work. I also wish the flavor was a bit stronger. Instead of using green tea extract, please switch to a non-staining caffeine source. I was really excited to try these, but until the formula changes, I’ll stick with Ultra pouches.
