Predicting your maximum height is really not a reasonable endeavor...and you may have very little control over this. Your genes are the driving factor, and true, nutrition and hormones may play a role in the eventual outcome. If it helps you at all to know that at age 16 I was about 165cm and I continued to grow until about age 23, where my height leveled out at 170cm. After starting T at age 40, my height has increased a few more centimeters. Not sure that I actually grew, but I most likely stand up taller due to chest surgery and enhanced confidence.
You may want to think in terms of treating your body well and feeding it with balanced nutrition, without skimping on the protein. There is really no way you will ever know if your growth is enhanced by T or if you just end up where you are genetically programmed, but you do have control over the fuel you give your body!
