Growth Hormone Axis Education Protocol
Comprehensive educational overview of the GH/IGF-1 axis for clinician discussion
• This protocol is provided for educational and informational purposes only. It does not constitute medical advice, a diagnosis, a treatment plan, or a prescription.
• All dose ranges, frequencies, durations, and compound selections must be determined by a licensed healthcare professional based on your individual medical history, lab results, and clinical assessment.
• Lab monitoring may be required depending on the compound(s), individual health status, and duration of use. Discuss appropriate monitoring protocols with your clinician.
• Do not use any peptide compound if you are pregnant, breastfeeding, a minor, or have uncontrolled medical conditions without explicit direction from your physician.
Overview
A foundational educational protocol explaining how the growth hormone axis works, what research compounds interact with it, and what questions to bring to an endocrinologist.
Mechanism Summary
The GH axis involves hypothalamic GHRH → anterior pituitary GH release → liver IGF-1 production. Secretagogues can stimulate this axis through GHRH receptor or ghrelin receptor pathways. Downstream effects include metabolism, body composition, tissue repair, and aging-related changes.
Intended Goal
Build foundational understanding of GH axis before clinical consultation
CJC-1295
GH secretagogue / GHRH analogue
Long-acting GHRH analogue. Often studied with a ghrelin mimetic. Catalog reference.
Sermorelin
GH secretagogue / GHRH analogue
Short-acting GHRH analogue with established clinical use context. Catalog reference.
Ipamorelin
GH secretagogue / ghrelin mimetic
Selective ghrelin receptor agonist. Frequently paired with CJC-1295. Catalog reference.
GHRP-2
GH secretagogue / ghrelin mimetic
Potent ghrelin receptor agonist. Higher GH pulse amplitude than Ipamorelin. Catalog reference.
Research reference values only. Confirm all parameters with current literature and your clinician.
Who may be a candidate
- ✓Adults exploring GH axis options with their endocrinologist
- ✓Individuals with clinician-diagnosed GH deficiency
Exclusions
- ✕Not for individuals seeking self-directed GH optimization without clinical evaluation
Do I have documented GH deficiency?
What should my target IGF-1 range be for my age?
How often would you check my labs?
What are the cancer risk considerations given my history?
