Pending medical review Updated October 16, 2026

What is it?

Sermorelin is a lab-made peptide. It is a short copy of a natural body signal that tells your body to make growth hormone.

Why do people use it?

Some people say it helps with energy, muscle, sleep, or aging. These are claims. They are not proven facts for those uses.

Does it really work?

The FDA once approved sermorelin under the brand name Geref. FDA records now list every Geref product as "Discontinued." That means it is no longer sold as an approved brand in the US. An old approval does not prove it helps with aging or muscle.

Is it safe? Side effects

  • There is no current FDA-approved sermorelin label to check side effects against.
  • Any sermorelin sold today is not the approved Geref product.
  • Ask a doctor about risks before using any growth-hormone product.
