Hello, I am a 26m, i have 5 7 . The issue is, that want to be taller so i have looked for ways to improve my height. For 2 weeks ago i am doing yoga, and hanging exercise regularly. So far this is the only way to reach my goal. But i wanted more, and i was curious about ways to increase also the length of my bones or the cartilage. (I would be happy with any result) I am not sure if my growth plates are fused, but more likely they are. Limb lengthening is not an option for me so i have looked for other options (supplements) which maybe are just scam, but i decided to give them a chance and first understand how they work (or at least how could :D). I have contacted some companies and one of them gave me some information: Dear Customer, Thank you for your email. Growth Boom will still regenerate your fused bones. It is a very complex process. If you are familiar with medical science we can explain it to you. Please check the attached schema. In this schematic image , you can see how Growth Boom stimulates growth. A schematic representation of hormonal control of body development and growth . Kisspeptin from Kiss neurons stimulates GnRH secretion by a direct effect on GnRH neurons. KiSS-1 neurons in the ARC involves in the negative feedback regulation of GnRH/LH by sex steroids. The expression of KiSS-1 mRNA in the arcuate is inhibited by estradiol (E), and testosterone (T). + = stimulation, – = inhibition Please let me know if you need further information Sincerely I am curious about your thoughts.
