What This Study Found

GH secretagogues (GHRP-6, hexarelin, MK-677) offer clinical advantages over GH injections: oral availability, physiological pulsatile release patterns, and multiple applications from GH deficiency to aging, obesity, and critical illness.

Key Numbers

How They Did This

Comprehensive clinical pharmacology review covering GH biology, regulation, GH secretagogue pharmacology, and clinical applications across multiple indications.

Why This Research Matters

This serves as the definitive clinical pharmacology reference for practitioners and researchers working with GH and GH secretagogues across all therapeutic applications.

The Bigger Picture

The clinical landscape for GH therapy is evolving from daily injections to oral secretagogues. This review maps the complete pharmacology guiding this transition.

What This Study Doesn't Tell Us

Review from 2002. Some clinical applications were still in development. Long-term safety data for chronic GH secretagogue use was limited.

Questions This Raises

  • ?Will oral GH secretagogues be approved for GH deficiency?
  • ?Which clinical application offers the best risk-benefit profile?
  • ?How should chronic GH secretagogue therapy be monitored?

Trust & Context

Key Stat:
Comprehensive reference Covers all GH secretagogues (GHRP, hexarelin, ipamorelin, MK-677) across all clinical applications — the complete clinical pharmacology guide

Frequently Asked Questions

What GH secretagogues are available?

Major compounds include GHRP-6, GHRP-2, hexarelin, ipamorelin, and MK-677. They differ in selectivity, route (injectable vs oral), and side effect profiles. MK-677 is the most advanced oral option.

Are GH secretagogues better than GH injections?

They offer potential advantages: oral dosing (MK-677), more natural GH release patterns, and the body's own feedback regulation. Whether they fully match GH injection efficacy for all conditions is still being determined.
