IGF-1 LR3 Overview
IGF-1 LR3 is commonly used to describe a modified IGF-1 analogue related to Des(1-3)IGF-I research.
Des(1-3)IGF-I lacks the first three amino acids of native IGF-I, reducing its interaction with certain IGF-binding proteins and increasing its biological potency in experimental systems.
Product Information
Research has shown that Des(1-3)IGF-I can be substantially more potent than native IGF-I in cell and animal models because of reduced binding to IGF-binding proteins.
However, commercially marketed “IGF-1 LR3” products should not automatically be assumed to have been tested in the same studies.
How Does IGF-1 LR3 Work?
Des(1-3) IGF-1 interacts with IGF-1 receptors while displaying reduced binding to several IGF-binding proteins, increasing the amount of active peptide available to tissues.
IGF-1 LR3 Benefits & Effects
Supports Muscle-Growth Research
IGF-1 signaling is strongly associated with cellular growth and protein metabolism. Experimental Des(1-3)IGF-I research has demonstrated enhanced growth-related effects compared with native IGF-I.
Supports Cell-Growth Research
IGF-1 receptors regulate pathways involved in cell growth, proliferation, and survival. Des(1-3)IGF-I has therefore been investigated in cellular-growth models.
Supports Tissue-Growth Research
Animal studies have demonstrated enhanced growth responses following Des(1-3)IGF-I administration, making the analogue relevant to tissue-growth research.
Supports IGF-Receptor Research
The altered interaction with IGF-binding proteins makes Des(1-3)IGF-I useful for investigating how free IGF signaling differs from the activity of native IGF-I.
IGF-1 LR3 Side Effects
Potential concerns associated with excessive IGF signaling include hypoglycemia, edema, headache, joint discomfort, and abnormal tissue growth.
IGF-1 LR3 Dosage
A 20–100 mcg/day dose is frequently reported online, and recent Reddit discussions include users reporting 50–100 mcg/day.
