Growth Hormone Secretagogues

I’ve gotten some very nice results from a product called Secretagogue-One but I understand that a product called Pro-hgh by Nutraceutics came first Has anyone used either or both of these products? I’m wondering why I should pay more for less dosages of Pro-hgh when secretagogue -One works quite well. Opinions from all you over 35 athletes with some experience with these products.
