What Is GH (Growth Hormone)?
Category: Biology
A hormone produced by the pituitary gland that stimulates growth, cell reproduction, and regeneration. GH secretagogue peptides stimulate the body's natural GH production.
Detailed Explanation
Growth Hormone (GH), also known as somatotropin, is a 191-amino acid protein hormone produced by the anterior pituitary gland. It plays central roles in growth, body composition, cell repair, and metabolism. GH is released in a pulsatile pattern, with the largest pulses occurring during deep sleep. Natural GH production declines with age, a process called somatopause. GH secretagogue peptides work by stimulating the body to produce and release more of its own GH, rather than introducing exogenous hormone.
Practical Context
GH secretagogue peptides like Ipamorelin and CJC-1295 offer an alternative approach to GH optimization compared to direct HGH injection. By stimulating natural production, these peptides maintain the body's feedback mechanisms and produce a more physiological pulsatile release pattern. They are taken on an empty stomach because food (especially carbs and fats) can blunt the GH response. Timing doses around sleep can enhance the natural nocturnal GH surge.
Frequently Asked Questions
What is the difference between GH peptides and HGH?
GH peptides stimulate your pituitary to produce its own growth hormone naturally, maintaining feedback loops. HGH is direct injection of synthetic growth hormone, which can suppress natural production.
Why do GH peptides need to be taken fasted?
Food, especially carbohydrates and fats, triggers insulin release which blunts the GH response. Fasting for at least 2 hours before and 30 minutes after ensures maximum GH release.

Related Terms
- GHRH (Growth Hormone Releasing Hormone) - A category of peptides that amplify growth hormone pulses. Examples include CJC-1295 and Sermorelin. Most effective when combined with a GHRP.
- GHRP (Growth Hormone Releasing Peptide) - A category of peptides that trigger growth hormone release from the pituitary gland. Examples include Ipamorelin, GHRP-2, and GHRP-6.
- Secretagogue - A substance that promotes the secretion of a hormone. GH secretagogues stimulate the pituitary gland to release growth hormone naturally, unlike exogenous HGH which directly introduces the hormone.
- Pulsatile Release - The natural pattern of GH secretion in which hormones are released in bursts rather than continuously. GH peptide stacks aim to mimic this natural pattern.
