Growth Hormone Research Peptides
This category contains growth hormone-releasing hormone (GHRH) analogues, ghrelin mimetics, and related secretagogues studied for their interactions with the hypothalamic-pituitary-somatotroph axis. These are among the most established classes of research peptides, with decades of published preclinical and human research.

Key compounds:

Sermorelin — 29-AA GHRH(1-29) fragment; acts at GHRHR on pituitary somatotrophs; reference GHRH analogue in research
CJC No DAC (Mod GRF 1-29) — Stabilized GHRH fragment with modified residues; improved half-life over sermorelin
Ipamorelin — Selective ghrelin receptor (GHS-R1a) agonist; studied for GH pulse stimulation without cortisol effects observed with earlier secretagogues
CJC + Ipamorelin — Combination targeting both GHRHR and GHS-R1a simultaneously; common research combination
IGF-1 LR3 — Long arginine 3 variant of insulin-like growth factor-1; downstream effector of GH; used in muscle biology and receptor research
Tesamorelin — GHRH analogue with trans-2-hexenoic acid modification; extensively studied in visceral adiposity and lipodystrophy research

Research uses include: pituitary axis characterization, GH secretion dynamics, receptor binding assays (GHRHR and GHS-R1a), and downstream IGF-1 pathway studies. All compounds ≥98% purity, HPLC + MS verified.
