Saw a supplement brand selling oral GHK-Cu capsules with big 'anti-aging' claims. My understanding is tripeptides get destroyed in the stomach and this is basically charging $60 for expensive copper. Am I wrong?

You're right. Oral tripeptides are almost entirely hydrolyzed in the gut. Any copper that survives is just copper. You can get that from beef liver for $2.

Waste of money. The oral peptide supplement category is 95% people charging a premium for 'peptide' on the label when what's surviving to circulation is amino acids or nothing.

If it could be taken orally it'd be a drug, not a $60 bottle of capsules with a website that won't tell you what the active dose is.

Tried it for like 4 weeks, felt nothing. Switched to subq and noticed actual changes within days so yeah, oral peptides are a scam. The stomach acid thing isn't even controversial, it's just basic biology. Save your money unless you're willing to pin it.

tbh the copper angle is way overblown. GHK-Cu is like 2-3% copper by weight, you're not getting meaningful amounts from a capsule. that said yeah oral peptides are mostly theater, your stomach is basically a blender. the only way this makes sense is if theyre doing some kind of enteric coating or liposomal delivery but nobody selling $60 bottles is actually doing that consistently. if you want to test it just grab some subq and see if you actually notice anything different, then you'll know if it was the peptide or just placebo from the first run.
