What a pile of baloney! Being on the low end, or in the middle, or the average height range is not a disorder; and people who have genuine growth problems (those not expected to reach within the normal range) either live with being small or else get the assistance of a legitimate physician (or several). These spammers need a new marketing approach because they're coming across like "snake oil salesmen". This is not a US company, for the record.
Genetically many women are shorter than others, and it shows someone has very little scientific knowledge for implying otherwise. I used to wear heals because pants are just way too long in the US, and I did not always want to sew these up. No I just buy shorter pants and wear flats. I like my height and could care less about those who promote products suggesting people should put on height.
People will market anything online these days, which doesn't exactly make it right...I remember seeing an ad for some type of cream to get rid of man boobs, which made me laugh more than anything else!!
