I'm underweight for my age (19) and was wondering if there was any effects in the long run. In other words, if you have taken it on day 1 has there been any negative body changes (ex. Excessive weight gain, even after discontinuing the product) on day 365? My parents are not very amused by this idea but I'm a bit desperate at this point. And I know that every body type is different but I just wanna get some sort of general idea you know, as I do consider and understand why my parents would not go for such a product. Please reply I would really appreciate it!!
