What's your opinion on TB-500/GHK-Cu peptide chatter online?

Every time I look up TB-500 or GHK-Cu, the internet splits into two camps: miracle recovery/skin fix and pure hype with risky shortcuts.

I'm not asking for sourcing or protocols. I'm trying to understand the chatter itself. What claims do you see repeated most (injury recovery, inflammation, skin/hair, scar healing), and which ones seem most exaggerated or unsupported?

If you've researched this deeply or discussed it with a clinician, what's the biggest thing people online get wrong about TB-500/GHK-Cu? And what red flags make you ignore a post immediately?
