- This table contrasts oral vs injectable Sermorelin across bioavailability, administration, cost, and clinical use. Demonstrating why route of administration determines efficacy.
- Oral (capsule/spray)
- <1%. Peptide bonds cleave in stomach acid before absorption
- Zero. Pepsin degrades the 29-amino-acid chain within 15–30 minutes at pH 2.0
- Swallow capsule or spray under tongue daily
- Marketed as supplement; no clinical growth hormone data supports efficacy
- Not viable for therapeutic GHRH receptor activation. The peptide does not reach systemic circulation intact
- Subcutaneous injection
- 70–85%. Peptide enters bloodstream directly from adipose tissue
- Not applicable. Bypasses digestive tract entirely
- Inject 0.3–0.5mL into abdominal subcutaneous tissue, typically before bed
- Clinical growth hormone optimization protocols; anti-aging medicine
- Gold standard route. Delivers intact peptide to pituitary receptors with measurable GH pulse response
- Modified oral peptides
- 5–15% (encapsulated or chemically altered to resist pepsin)
- Partial. Modifications protect some bonds but alter receptor affinity
- Varies by formulation. Often requires enteric coating or liposomal encapsulation
- Experimental formulations in research phase; not commercially available for Sermorelin specifically
- May improve absorption but changes the molecule's structure. Efficacy and safety profile differ from native Sermorelin
