Do all vendors accept the same GHK-Cu coupon?
No. Coupon codes are vendor-specific — a code from Vendor A won't work at Vendor B. Each row in the table below shows which vendor's checkout the code applies to. Apply only the code matching the vendor you're buying from.
Are GHK-Cu coupons stackable with bulk discounts?
Stackability depends on the vendor's policy. Most vendors allow ONE promo code per order — a coupon OR a bulk-tier discount, not both. A few vendors (typically the larger storefronts) allow stacking; check the vendor's checkout page after applying the code to confirm.
