When do arms and legs stop growing?

[T_T]

I'm 17 years old
My limbs are very short compared to my siblings (I suspect this is because of growth stunting)
The official studies on arm and leg growth indicate that legs do not grow after the (?last?) growth spurt at around 15 maybe 16 years old

I'm asking this because
1) I want to start taking mk677/AIs and if I don't get limb growth I won't bother
2) My limbs are very short and if only my spine grows I'll look deformed

Depends on the person, but around 18 seems to be the case for most
