01 The product name is not a ruling Halal means permitted; haram means prohibited. A name such as peptide or GHK-Cu alone does not establish the finished product’s status.
02 Ask about ingredients and production Check ingredient sources, other ingredients and manufacturing processes. Ask the supplier for product-specific information.
03 Check what a certificate covers Confirm the exact product and current certificate with its certifier. If you remain uncertain, ask a trusted scholar using the product details.
