What was the old brand?
A hormone is a substance the body makes to carry a message from one part of the body to another.
In 1990, the US approved sermorelin, sold as Geref, for use in a test. The medicine was given to check whether the pituitary gland could release growth hormone.
Another approval followed in 1997 for children whose growth was affected by a growth hormone shortage.
The pituitary is a small gland below the brain. The first use was to get a test result; the second was treatment for children. FDA is this notebook’s shorthand for the Food and Drug Administration, the agency that oversees US drugs.
What changed?
Geref’s maker ended sales in 2008 and requested an end to the approvals.
Both approvals ended on June 18, 2009.
The FDA’s 2013 finding said neither safety nor effectiveness problems explained Geref’s departure from the market.
The 2013 finding explained why Geref left the market. It did not approve any sermorelin medicine offered today.
Is the old product available now?
No sermorelin product carrying FDA approval was being sold in the US as of September 2026.
Sermorelin had never been approved for adult treatment.
Approved growth hormone medicines do exist for adults with a true growth hormone shortage.
Ask which product is being proposed now and what supports the intended use. A history lesson alone does not answer either question.
