Hi. I m a 19 year old guy who is 5 7 . I came across this program called Grow Taller 4 Idiots which basically is an e book which consists of the proper diet, the vitamins and minerals necessary to gain height, the sleep routines, etc. It also describes the stretching exercise routine and a HGH cocktail that we re supposed to drink to boost our body s HGH. It s made by grinding 43 grams of cabbage and broad beans, each and one tomato. Now, my question is, is this effective? Can i grow taller after puberty at the age i currently am? Because I would love to add a couple more inches to my height. My father is 5 6 and my mother is 5 2 . Thank you.
