Is PCT Needed for HGH?

So far, my research has concluded that HGH won’t shut down your natural growth hormone secretions, so I just want to confirm with some opinions on here.

I’ve heard that people go on MK-677 or peptides (GHRPs, etc.) to ‘kickstart’ natural growth hormone release again after pinning GH.

My question would be, would HGH shut down natural production of GH? And would it be fine to abruptly stop HGH with no PCT protocol?

There is no pct protocol for HGH. It shuts down natural production and when you cease it starts back up again rather quickly. Explain how much you want to use, for how long you want to use it, and justify the unholy cost of a drug that 99% of gym rats do not need.
