The short answer
The small adult studies did not establish those promises.
Some small studies in older adults found higher growth hormone after sermorelin or a closely related medicine.
That is a result to discuss, rather than a guarantee about daily life.

Check who was studied
The main study linked to the old approval enrolled 110 children with diagnosed low growth hormone.
The report covered 86 children, who grew faster, but included no other group to compare growth with.
Check how long people were followed
The adult studies were small and short; they cannot tell us what happens after years of use.
How long the adult studies ran Corpas: 10 older men, followed for 2 weeks.
Vittone: 11 older men, followed for 6 weeks.
Khorram: 19 older adults, followed for 16 weeks.
Khorram tested a medicine closely related to sermorelin, not sermorelin itself.
Check which result changed
The adult studies that measured body fat tested sermorelin or a closely related medicine and found no change in body fat.
In Khorram's study, a medicine closely related to sermorelin did not improve sleep quality.
Ask for evidence that fits your goal
Was this same medicine tested in adults like me, for the change I hope to feel? What would count as a useful result?

Brief source notes
- Children's growth study
The study summary reports the growth results and how the research was done.
- Corpas adult hormone study
The study summary describes changes in growth hormone over a short time.
- Vittone adult study
The study summary reports blood test results and changes in the body separately.
- Khorram study of a medicine related to sermorelin
This study used a different medicine, so ask how its results apply to sermorelin.
