Ipamorelin

Ipamorelin – Selective GH Secretagogue for Endocrine and Regeneration Research

Ipamorelin is a synthetic pentapeptide and highly selective agonist of the growth hormone secretagogue receptor (GHSR‑1a), developed to investigate controlled, pulsatile release of growth hormone (GH) without significant stimulation of cortisol, prolactin, or other pituitary axes. By mimicking key actions of ghrelin on the pituitary and hypothalamus, this targeted secretagogue is widely used in models of body composition, musculoskeletal repair, bone growth, and metabolic regulation.

Key features

• Highly selective GH release: Ipamorelin robustly increases GH secretion in animals and humans with minimal impact on ACTH, cortisol, prolactin, FSH, LH, or TSH, distinguishing it from earlier GHRPs.

• Ghrelin‑receptor agonism: Binds GHSR‑1a, triggering cAMP/PKA signaling, activation of GHRH neurons, and direct somatotroph stimulation while preserving physiological GH pulse patterns and feedback.

• Anabolic and metabolic focus: Preclinical work shows increased longitudinal bone growth, body‑weight gain, and enhanced protein synthesis, supporting its use in growth, bone, and body‑composition models.

• Combination potential: Often paired with GHRH analogs such as CJC‑1295 to explore synergistic effects on GH/IGF‑1 axis activation and extended anabolic signaling.

  
  

Research applications

Ipamorelin is employed in experimental systems examining:

• GH/IGF‑1 axis dynamics, including acute and chronic changes in GH pulse amplitude, IGF‑1 levels, and downstream anabolic markers.

• Body composition, metabolism, and recovery, where investigators track lean mass, fat mass, nutrient partitioning, and exercise recovery under increased endogenous GH.

• Bone and connective‑tissue biology, including longitudinal bone growth, bone mineral characteristics, and collagen‑rich tissue support in tendons, ligaments, and joints.

• Broader longevity and wellness‑adjacent models exploring sleep architecture, neuroendocrine function, and repair processes linked to physiologic GH rhythms.

  
  

Recommended handling

• For controlled laboratory research use only, by qualified professionals.

• Store in a cool, dry environment away from light; follow institutional SOPs for peptide storage, reconstitution, aliquoting, and disposal.

• Investigators should consult current literature when designing dosing, timing (often evening/overnight in models), and outcome measures for endocrine and regenerative endpoints.
