Another consideration is that they don't want these products being sold online to begin with. They are supposed to be brick and mortar only, so that kind of goes along with your line of thought questioning the legitimacy of the ones selling it online.Has anyone ever bought from the sites that pull up via search for this? I know things are always quite a bit more expensive thru brick and mortar, but $50 seems too good to be true given the additional ingredients in Byld besides PA, as well as the dose of PA.
