What sermorelin does

How sermorelin works

A hormone is a chemical message the body makes. Sermorelin is a lab-made copy of part of the message that tells a gland to release growth hormone.

That gland is the pituitary, which sits under the brain. It releases growth hormone in response to the message. Sermorelin does not supply growth hormone itself.

Growth hormone helps children grow. Releasing more of it does not by itself prove a benefit for an adult.

Sermorelin belongs to a group of medicines that prompt growth hormone release. The US drug regulator is called the Food and Drug Administration (FDA). It says these medicines cannot work if the gland cannot release that hormone.

The older approval had narrow uses

Geref (sermorelin) was approved for testing growth hormone release in 1990.

In 1997, it was also approved to treat poor growth in children with a growth hormone shortage of unknown cause.

Those approvals did not cover adult goals such as better energy, sleep or body shape.

At the maker’s request, both approvals were withdrawn on June 18, 2009.

In 2013, FDA found that safety or effectiveness problems were not the reason Geref left the market.

That finding explained why Geref had stopped being sold. It did not approve the medicines pharmacies make now.

As of September 2026, no FDA-approved sermorelin product is being sold in the US.

A compounded medicine is one a pharmacist or doctor makes to order.

In September 2026, these made-to-order medicines remain unapproved by FDA. FDA does not check their safety, how well they were made or how well they work before sale.
