Increasing GH will help with height and bone masculinization, but pinning hgh is the less stable option with higher peaks, which is why I recommend an oral like mk677.
The major thing to note, if you're pinning hgh it's easier to run into issues like Acromegaly which will make you look retarded.
A secretagogue isn't free from risk of Acromegaly, but is less likely as long as you're not megadosing like a moron.
Also another major thing, if you're looking at androgens, you should wait a couple years before you get into anything like test, though something like mtren or fluoxymesterone are usable.
But if you raise your test levels too high at your age, you can limit your height growth potential by increasing estrogen, though mtren, fluoxymesterone, and other synth-test analogues avoid this by not metabolising into estrogen.
