Growth Hormone Peptides Peptides

Growth Hormone Secretagogue Research

Growth hormone peptides modulate the hypothalamic-pituitary axis to stimulate endogenous GH release. This category spans GHRH analogues like CJC-1295 and Sermorelin, ghrelin mimetics such as Ipamorelin and GHRP-6, and direct growth factors including HGH and IGF-1 LR3. Together, they represent the most well-characterized peptide class in endocrinology research.

Key Research Highlights

GHRH + GHRP combinations produce synergistic GH pulses - see our pre-formulated blends
Ipamorelin is the most selective ghrelin mimetic - stimulates GH without significant cortisol or prolactin elevation
Tesamorelin is FDA-approved for HIV-associated lipodystrophy, validated for visceral fat reduction
CJC-1295 with DAC provides sustained GH elevation (8-10 day half-life) vs No DAC's pulsatile release

The GH Axis

Understanding the growth hormone axis is essential for selecting the right peptide for a given research objective. GHRH analogues and ghrelin mimetics work at different points in the signaling cascade.

GHRH Pathway

CJC-1295, Sermorelin, and Tesamorelin bind to GHRH receptors on pituitary somatotrophs, directly stimulating GH synthesis and release. The DAC (Drug Affinity Complex) modification on CJC-1295 extends albumin binding and half-life.

Ghrelin Mimetic Pathway

Ipamorelin, GHRP-2, GHRP-6, and Hexarelin activate the growth hormone secretagogue receptor (GHS-R1a). When combined with a GHRH analogue, the two pathways produce a GH pulse far greater than either alone.

Reconstitution & Dosing

All GH peptides require bacteriostatic water for reconstitution. Use our reconstitution calculator and dosage calculator for precise measurements. For syringe volume conversions, see the syringe unit calculator.
