TRT + HGH is the natural progression, especially as you get older. But if you are younger or trying to put that off as long as possible, Kisspeptin absolutely works. It's not going to move mountains, but if you combine Kisspeptin with proper sleep, diet, and training, you're going to maximize possible results. Stacking it with CJC / IPA is also the right call.
Get your bloodwork done as a baseline and then start the Kisspeptin cycle.
