You are not the first one here who tries to increase his height without ll.
I said this before and I will say it again, I have tried everything(yes literally every method, technique, supplement, exercise, diet etc..) in the last three years and I could not even gain 1 cm. want my advice? just don't waste your time and focus on planning for a ll surgery if you really want to become taller . Maybe save money, read diaries, read doctor profiles, contact doctors etc...
Or, you can wait for at least 20+ years till they discover a magical medicine that increases height, your choice.
Btw, one of my uncles is short (5 feet 2 inches), he is a doctor, his son is 18 years old now and he was only 5 feet, my uncle prescribed him hgh injections (somatropin) when he was 15, guess how tall he is now? 5 feet 3! And he has stopped growing like you!
I am a pharmacist, I read many research papers regarding hgh related height increase, studies showed that hgh may only give extra 2-3 inches over the expected genetic height, and that is when the patients start taking injections when they are in their early teenage years 13-14.
And let's not forget how expensive these injections are. A three years courses would probably cost you no less than $60000(depending on the quality and effective dose).
