This is similar to what
@Jin23 was saying earlier in this thread. I'm putting what I found here but since I'm largely ignorant about this stuff I'm not putting the following as truth but merely as info I found. I would wonder if Jin23 would agree with what is said because these guys could be quacks. I don't know much about Seeds nor J Campbell. I do know that they have a following FWIW.
I was listening to this yesterday.
Highlights...
Dr. Seeds says GHRH like tesamorelin will up regulate that pituitary secretagogue and gets the machinery ready for production of endogenous GH but it won't release it
Somatostatin inhibits the release of it
GHRPs like ipamorelin will stop somatostatin inhibition (will also get body to produce endogenous GH)
Dr. Seeds says use ipamorelin and tesamorelin together at night and then in the morning use ipamorelin
On a side note, Jay says ipamorelin puts him to sleep.
They get into this about 40m40s into this video
