What is Sermorelin?
Sermorelin is a synthetic peptide composed of 29 amino acids. It is an analogue of the endogenous hormone GHRH (Growth Hormone Releasing Hormone), which stimulates the pituitary gland to secrete its own growth hormone (GH).
Unlike direct administration of recombinant GH, sermorelin supports the natural regulation of secretion by preserving physiological feedback mechanisms.
Observations on Sermorelin
Sermorelin is being studied for its possible effects on:
Stimulation of growth hormone secretion – in research models, an increase in endogenous GH from the pituitary gland has been observed.
Muscle mass and strength – an effect on protein and collagen synthesis has been described.
Joint and bone health – an effect on bone mineralization has been observed.
Regeneration and recovery – in experimental conditions, a shortening of recovery time after exercise has been described.
Sleep quality – observed effect on deep sleep phases.
Scientific data
Sermorelin has been studied in clinical and preclinical settings.
In endocrinology, it has been used for the diagnosis of GH deficiency and as a therapeutic agent to stimulate endogenous growth hormone.
In gerontology and restorative medicine, it is being studied for its potential to improve body composition, muscle tone, and bone density.
In sports medicine, there is interest in its effects on recovery and adaptation after exercise.
Dosage and administration
The scientific literature describes subcutaneous administration once daily at 100-300 μg, usually before sleep, to synchronize with physiological GH pulses.
At 5 mg + 3 ml bacteriostatic water: 1.67 mg/ml → 0.06 to 0.18 ml daily
At 10 mg + 3 ml bacteriostatic water: 3.3 mg/ml → 0.03 to 0.09 ml daily
Example values for 5 mg:
0.06 ml = 100μg
0.18 ml = 300 μg
0.15 ml = 250 μg
0.30 ml = 500μg
0.45 ml = 750μg
Example values for 10 mg:
0.03ml = 100μg
0.09ml = 300 μg
0.15 ml = 500 μg
0.30 ml = 1.0 mg
Application in sports
Sermorelin is banned by WADA for use in professional sports because it may:
- stimulates the secretion of growth hormone
- improve tissue repair
- increase muscle mass and strength
- helps reduce fat
Possible side effects
Side effects are usually rare and mild, and include:
- redness or pain at the injection site
- headache
- dizziness
- mild fluid retention
Less commonly, insomnia or palpitations are observed.
