It's so tough, in my opinion, to get people on the natural GH train. Arguably most OTC oral GH boosters are really only worth what they provide in deeper sleep/recover/possible strength increase. If you can find them for a good price, go for it. But if too expensive, people will typically spend money elsewhere.
I've used I-GH-1 sporadically, which isn't good. You really need to take it for a couple months to notice the benefits. I did notice better sleep, which for me was amazing. I felt better and more refreshed each morning.
