IGF-1

Insulin-like growth factor 1, a hormone produced primarily by the liver in response to growth hormone. Mediates many of GH’s anabolic effects including muscle growth, bone density, and tissue repair.

Frequently Asked Questions

What is IGF-1?
Insulin-like growth factor 1, a hormone produced primarily by the liver in response to growth hormone. Mediates many of GH’s anabolic effects including muscle growth, bone density, and tissue repair.
Why is IGF-1 important in peptide research?
IGF-1 is a key pharmacological concept that determines how peptides interact with the body. Understanding this term helps practitioners optimize dosing protocols, predict therapeutic outcomes, and minimize side effects.

Related Terms

Growth hormone secretagogue

A compound that stimulates the pituitary gland to release growth hormone by activating the ghrelin receptor or GHRH receptor. Includes peptides (ipamorelin, GHRP-2, GHRP-6) and the oral compound MK-677.

GHRH

Growth hormone-releasing hormone, a 44-amino acid hypothalamic peptide that stimulates pulsatile GH secretion from the anterior pituitary. Sermorelin, CJC-1295, and tesamorelin are synthetic analogs of GHRH.

Related Peptide Profiles

MK-677

Ibutamoren, an oral growth hormone secretagogue that mimics ghrelin signaling to increase GH and IGF-1 levels over 24 hours.

CJC-1295

A synthetic growth hormone-releasing hormone (GHRH) analog that stimulates pulsatile GH secretion. Available with or without DAC (Drug Affinity Complex).

Ipamorelin

A selective growth hormone secretagogue that stimulates GH release through the ghrelin receptor with minimal effect on cortisol or prolactin.
