Height of an individual is determined by Genetics, Environmental & Nutritional factors and Hormonal
factors (most important the Growth Hormone
secreted by pituitary gland
An individual stops growing in height after the fusion of the Epiphyses (growth plates) of the long bones, which occurs by the age of 19-22 yrs in males.
So...as you have already crossed the above mentioned age group, there is no chance of achieving your dream height except with surgical means.
One more thing...avoid consuming any over the counter medication
which claim to boost your growth hormone & increase height...it may be harmful.
Wishing you Good Health.
Thanks and take care.
