Got a question about your order, your routine, or whether GHK Labs is right for your skin? You're in the right place.

GHK Labs is run by a tight team of 8 people who actually use the product, know the research behind it, and answer every email themselves. No bots. No scripts. No outsourced support inbox where your message disappears.

The fastest way to reach us: send us a note below or email hello@ghklabs.co. Most messages get a real reply the same business day, and never longer than 24 hours.

A quick thank you. Every order you place keeps a small, independent brand going. It also helps us put the right dose of GHK-Cu into more people's bathrooms instead of another marketing budget. That means a lot.

– The GHK Labs Team

P.S. Already ordered and wondering when it'll land? Most orders ship within 1–2 business days and arrive in 7–10. Your tracking link will hit your inbox the moment it leaves our warehouse.
