The most-studied GHRH analog — FDA-approved diagnostic with 30+ years of clinical data
Sermorelin acetate is a synthetic 29-amino acid peptide corresponding to the first 29 residues of endogenous growth hormone-releasing hormone (GHRH 1-44). It represents the minimal active fragment required for full biological activity at the GHRH receptor. Sermorelin was FDA-approved in 1997 as Geref for the diagnosis of GH deficiency and was also approved for treatment of pediatric GH deficiency.

Dr. Richard Walker
Professor Emeritus, University of South Florida
Neuroendocrinologist and gerontologist. Over 40 years researching GHRH, aging, and the somatotropic axis. Led landmark sermorelin studies in elderly populations.
Sermorelin restores the amplitude of GH pulses that naturally diminish with aging. It works with the body's own feedback systems rather than overriding them — making it fundamentally different from exogenous GH.
200–300 mcg subcutaneous at bedtime. Can be used long-term with periodic monitoring. The pulsatile release preserves somatostatin feedback and pituitary health.

Dr. Thierry Hertoghe
President, International Hormone Society
Fourth-generation endocrinologist. Author of 'The Hormone Handbook.' 40+ years in hormone replacement therapy.
Sermorelin is the safest approach to GH optimization because it stimulates your own pituitary — it can only release as much GH as your pituitary can produce. This natural ceiling prevents the supraphysiological levels that cause problems with HGH.
200–500 mcg subcutaneous at bedtime. Can be combined with GHRP for enhanced effect. Long-term use is well-tolerated. Monitor IGF-1 every 3 months.

Dr. Ron Rothenberg
Clinical Professor, University of California San Diego
Founder, California HealthSpan Institute. Board-certified in emergency medicine and anti-aging medicine. Fellow of A4M.
Sermorelin is my first-line recommendation for patients wanting GH optimization. It has the best safety profile, preserves pituitary function, and has decades of clinical data behind it.
200–300 mcg subcutaneous nightly at bedtime on empty stomach. 3–6 month initial protocol with IGF-1 monitoring. Can be used as ongoing maintenance therapy.

Dr. Andrew Huberman
Professor of Neurobiology, Stanford University
Ph.D. in Neuroscience. Host of Huberman Lab.
Sermorelin is interesting because it was actually FDA-approved. It stimulates your pituitary to release its own growth hormone, which means the natural feedback loops stay intact. That's a fundamentally different approach than injecting HGH.
Bedtime dosing, fasted. Consider sermorelin as the most conservative GH optimization approach with the best risk-benefit profile. Combine with ipamorelin for synergistic effect.

Protocolo de Dosificación
3 FasesRégimen de dosificación paso a paso compilado de profesionales líderes e investigación clínica.
Start with conservative dose. Administer 30–60 minutes before bed on empty stomach. Check IGF-1 baseline and at week 4.
Titrate based on IGF-1 response and clinical effect. Add morning dose if IGF-1 response insufficient with bedtime-only dosing. Combine with ipamorelin for synergistic effect.
Sermorelin is well-suited for long-term maintenance. Many practitioners prescribe continuously with quarterly IGF-1 monitoring. No desensitization reported.
Add 2.5 mL bacteriostatic water to 5 mg vial = 2,000 mcg/mL. 200 mcg = 10 units; 300 mcg = 15 units on insulin syringe.
Cycling less critical than with GHRPs — sermorelin works through GHRH pathway with preserved somatostatin feedback. Many practitioners run continuous low-dose with quarterly labs. Optional: 3 months on, 1 month off.
Lyophilized: -20°C for 24+ months. Reconstituted: 2–8°C, use within 28 days. Relatively fragile peptide — protect from heat and light.
Subcutaneous injection at bedtime, fasted. The GH pulse aligns with natural nocturnal secretion. Can be combined with ipamorelin in the same syringe for synergistic effect.

Mecanismo de Acción
3 vías biológicas distintas a través de las cuales opera este péptido.
GHRH Receptor Activation
Sermorelin binds GHRH receptors on pituitary somatotrophs, activating cAMP/PKA signaling for GH synthesis and pulsatile release while maintaining somatostatin feedback.
- First 29 amino acids of GHRH — the minimal active fragment
- cAMP/PKA/CREB pathway drives GH gene transcription
- Natural somatostatin feedback preserved — prevents supraphysiological levels
Vittone et al. (1997) PMID: 9329323
Physiological GH Pulse Restoration
Unlike exogenous HGH which overrides pituitary function, sermorelin restores the amplitude of endogenous GH pulses while preserving the natural frequency and pattern.
- 24-hour GH secretion increased 95% in elderly men
- GH pulse amplitude increased 74% — frequency maintained
- Pituitary function enhanced rather than suppressed
Vittone et al. (1997) PMID: 9329323
Immunomodulation via GHRH Pathway
GHRH receptor activation has direct immunomodulatory effects including enhanced T-cell proliferation, NK cell activity, and balanced cytokine production.
- Direct GHRH receptors on immune cells (T-cells, macrophages)
- Enhanced natural killer cell activity
- Balanced pro- and anti-inflammatory cytokine regulation

Especificaciones
Cómo Funciona Sermorelin Acetate
Sermorelin is a synthetic 29-amino acid peptide corresponding to the first 29 amino acids of endogenous GHRH, which represents the minimally active fragment required for full biological activity. It binds to GHRH receptors on pituitary somatotrophs, activating adenylyl cyclase via Gs proteins to increase cAMP and stimulate GH gene transcription, synthesis, and pulsatile release. It preserves the natural GH feedback axis and promotes slow-wave sleep-associated GH secretion.
