Does GHK-Cu occur naturally in the body?

Yes.

GHK is a naturally occurring peptide found in human biological fluids and tissues, and it can bind copper to form GHK-Cu.

This is one reason researchers became interested in it.

However:

Natural occurrence does not automatically mean that injecting concentrated GHK-Cu is safe.

Many naturally occurring biological molecules can cause problems when administered at inappropriate concentrations or through inappropriate routes.WHERE TO BUY GHK-CU


18. How is GHK-Cu used in skincare?WHERE TO BUY GHK-CU

A typical consumer product may contain Copper Tripeptide-1 in a serum or cream.

The practical approach is generally to:

  1. Apply the product according to its manufacturer’s instructions.
  2. Introduce it gradually if you have sensitive skin.
  3. Avoid applying it to damaged or infected skin unless the product is specifically formulated and intended for that purpose.
  4. Stop if significant irritation occurs.
  5. Use sunscreen during the day because copper peptides are not substitutes for sun protection.

There is no universally established “best” cosmetic concentration for every purpose.
