Been hunting for copper peptide (GHK-Cu) and wanna see if anyone here’s got a plug that’s not charging clown prices.
Here’s what I found so far:
Retail sites (safe but $$$)
Bulk / raw sources (cheap af but risky)
From my math:
Problem: bulk stuff might be underdosed, cut with filler, or just dyed copper salts unless you test it.
So… who’s got the cheapest real GHK-Cu that ships to US? Bonus if they’ve got a batch-specific COA and not just some random PDF.
Here’s what I found so far:
Retail sites (safe but $$$)
- Peptide Sciences – $70 / 50mg
- Modern Aminos – $48 / 50mg
- Oxford Peptides (UK) – ~£39 / 50mg (ships to US)
- MedChemExpress – $55–$70 / 50mg
Bulk / raw sources (cheap af but risky)
- Made-in-China – $5–$10 per gram from manufacturers like YTBIO (this is prob where the retail guys buy it)
- IndiaMART – $50–$60 / 50mg but most look like middlemen or fakes
- Seen some sellers slapping Peptide Sciences labels on random blue powder
From my math:
- Retail is around $1–$1.40 per mg
- True bulk is $0.005–$0.01 per mg (20× cheaper) if it’s real
Problem: bulk stuff might be underdosed, cut with filler, or just dyed copper salts unless you test it.
So… who’s got the cheapest real GHK-Cu that ships to US? Bonus if they’ve got a batch-specific COA and not just some random PDF.
