HGH before puberty ends

[therealalex.com]

I'm going to hear often online the downsides of taking HGH before puberty ends, but is there any actual way to ascend taking it? I've done some research online about all the possible effects on taking HGH early on and for the most part I'm being told I can speed up growth and hence end with less growth than if I were to wait naturally. However what is on my mind is if it is worth taking if around the end of puberty (meaning most growth would have already happened) and I take advantage of what I have left to grow. Furthermore, I'd like to know if having seen relatively slow growth is a good sign of taking HGH. Regardless I'm aware that genetics are the main role player here but I would just like to hear other peoples outlook in this situation. Is there a realistic scenario where starting near the end of puberty produces a net growth benefit, or is that mostly cope? Thanks.
