GH Peptide

GH Axis Research Peptides

The growth hormone axis is regulated by two opposing hypothalamic signals — growth hormone releasing hormone (GHRH), which stimulates somatotroph release, and somatostatin, which suppresses it — with ghrelin acting through a separate receptor (GHSR) as a third input. The compounds in this category target those inputs through different receptors, which is why they are frequently studied in combination.

Two Distinct Mechanisms

• GHRH analogs — Tesamorelin and CJC-1295 (No DAC) are modified GHRH sequences studied for receptor affinity and degradation resistance relative to native GHRH
• Ghrelin receptor agonists — Ipamorelin acts at GHSR-1a and is studied for its selectivity profile compared with earlier secretagogues

Because the two act on separate receptors, combination vials exist specifically to support comparative work on additive or synergistic signaling in pituitary cell models.

Handling

These are lyophilized peptides — refrigerate on arrival, reconstitute with bacteriostatic water, and hold reconstituted material at 2–8°C. Related metabolic endpoints are covered under Metabolic Research.
