Legal Status and Safety

Online, sermorelin is often presented as a natural alternative to growth hormone. Its real position is more complicated: a former prescription drug whose licences have lapsed, which is now available mainly through special routes.

Medicines Regulators

• United States: Geref's approvals ended in 2009. In 2013 the FDA ruled that the product had not been withdrawn for safety or effectiveness reasons, which leaves the door open for compounded versions prescribed by a doctor.
• European Union: no sermorelin medicine is currently authorised. Selling it with health claims would fall under medicines law.
• United Kingdom: no sermorelin product holds a licence from the MHRA.
• Other countries: rules on importing and holding research peptides vary, so the local position always needs checking.

Sport

The World Anti-Doping Agency lists growth hormone releasing hormone and its analogues, including sermorelin, under class S2 of its Prohibited List, alongside other peptide hormones and growth factors. The ban applies at all times, not just during competition, and laboratories can detect sermorelin in urine.

What Is Known About Safety

In the children's trials and the small adult studies, sermorelin was generally well tolerated. Reported problems were mostly mild: flushing of the face, discomfort at the injection site and, in one adult study, a short-lived rise in blood fats.

What Is Not Known

• Long-term use in adults: no study has followed healthy adults on sermorelin for years.
• Raised IGF-1 over time: high IGF-1 levels have been linked to health risks in other settings, and the long-term effect of pushing them up with sermorelin is unclear.
• Product quality: today's material does not come from the original licensed production, and research-grade powders are not made to medicine standards.
• Who should not use it: without a licence there is no official patient leaflet setting out warnings or conditions where it should be avoided.

A Laboratory Reagent

Research-grade sermorelin is sold for experiments. It comes with no approved dose, no medical supervision and no route for reporting side effects.

Bottom Line

Sermorelin has a real medical history, but it is no longer a licensed medicine in Europe or the US. Athletes face sanctions if it is found, and anyone thinking about it for health reasons should talk to a doctor first.
