I am short in height at the age of 20, is there anything I can do?

Hey there,
I am a 20-year-old Turkish male who has a height of 5'7 (around 170 cms). My mother is around 4'11 and my father must be something like 5'9 (around 175 cms). I am one of the shortest guys among my relatives (we can say that at least 5 or 6 relatives are only a few cms longer than I am, but still). Having a short stature influenced my mental health in a bad way even though I have been trying to overcome the thought of it and get more positive with it. I even sometimes get bullied just because of it and it hurts me a lot. Other than these, I am a huge volleyball enthusiast and even though I have good technique and knowledge of the game I can't play it properly because of the apparent and unmodifiable disadvantages I have.

My sister who has a height of 5'1-5'2 (150-155 cms) is also suffering from the same situation but she also has scoliosis so not so sure if our short stature is caused by the same specific reason.

She once was referred to Genetics specialist and that specialist told my sister that if she was referred to her before the age of 21 she could have prescribe some sort of injections that could make her grow taller.

Now my sister thinks that I should get checked by a Genetics specialist and have those shots prescribed for myself but I am not so sure if they will work or not because I am a medical student and I know epiphyseal plates tend to stop growing at the age of 20-25.

I just wondered if there is anything I can do to grow even a few more inches at this point in my life. It will mean a lot to me if there is but even if there is not, I will just accept the truth and move on with it.

***I was on isotretinoin therapy for nearly 5 months at the age 15. I thought it could be one of the reasons why I was not able to grow longer.

Thank you for your attention.
