GHRH and GHRPs as Anti-Aging Therapeutics to Restore Declining Growth Hormone
GHRH and GHRPs offer promising approaches to restore age-related GH decline, addressing the visceral fat accumulation and metabolic changes of GH deficiency in aging.
Quick Facts
What This Study Found
GHRH and GHRPs can restore GH secretion in aging and disease, addressing the visceral fat accumulation and metabolic changes associated with GH decline.
Key Numbers
How They Did This
Review chapter discussing the pathophysiology of GH decline and the therapeutic potential of GHRH and GHRPs across aging and disease states.
Why This Research Matters
Age-related GH decline affects virtually everyone, contributing to body composition changes and metabolic deterioration. Secretagogue therapy offers a practical, physiological approach to restoring youthful GH levels.
The Bigger Picture
This review positioned GH secretagogues as anti-aging therapeutics, anticipating the current interest in peptide-based approaches to healthy aging.
What This Study Doesn't Tell Us
Review chapter; long-term safety of chronic GH stimulation in aging not fully established. Cancer risk with chronically elevated GH/IGF-1 is debated.
Questions This Raises
- ?Is long-term GH secretagogue therapy safe for aging populations?
- ?Which patients benefit most from GHRH vs. GHRP approaches?

What do these levels mean? →Frequently Asked Questions
Why does GH decline with age?
Multiple factors: the hypothalamus produces less GHRH, somatostatin inhibition increases, body fat accumulation (which suppresses GH) increases, and IGF-1 feedback becomes more inhibitory. The result is a progressive decline in GH pulsatility.
Are GH secretagogues better than GH injections?
Potentially. Secretagogues preserve the body's natural pulsatile GH release pattern and are self-limiting (the pituitary can only release what it has). GH injections bypass this regulation and can cause more side effects at higher doses.
