IGF-1 LR3 (1mg)

GF-1 LR3 – Overview

What is IGF-1 LR3?

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic version of human IGF-1, modified to increase its stability and extend its half-life in the body. IGF-1 is a key mediator of growth hormone (GH), driving muscle growth, cellular repair, and recovery. The LR3 version is 2–3 times more potent and remains active for significantly longer, making it a popular choice in performance, regenerative, and anti-aging therapies.

For Practitioners: Clinical Guidance

Mechanism of Action

IGF-1 LR3 binds to IGF-1 receptors in muscle and tissue cells, promoting protein synthesis, cellular proliferation, and tissue regeneration. It enhances the effects of growth hormone while bypassing the liver’s production of natural IGF-1, resulting in more direct systemic effects. The "long R3" modification prevents binding to IGF-binding proteins, allowing more active peptide availability.

Benefits

• Stimulates muscle growth and lean tissue development
• Enhances recovery from training, injury, or surgery
• Promotes fat loss and metabolic efficiency
• Supports nerve regeneration and cellular repair
• May improve skin, hair, and connective tissue health

Dosing Protocol

• Typical Dose: 20–100 mcg per day
• Frequency: Once daily, preferably post-workout or in the morning
• Route: Subcutaneous injection; intramuscular use also practiced in some settings
• Cycle Duration: 4–6 weeks; longer cycles require medical oversight due to potential desensitization

Monitoring

• Assess muscle mass, strength, recovery, and body composition
• Optional: IGF-1 serum levels, glucose/insulin sensitivity, and lipid profile
• Watch for signs of hypoglycemia, joint stiffness, or tissue overgrowth

For Patients: What You Should Know

What It Does

• Interested in long-term anti-aging and cellular repair benefits

How to Take It

• Inject under the skin once daily, ideally after exercise or in the morning
• Use only the amount prescribed by your practitioner
• Store properly and never exceed recommended cycle length

What to Expect

• Increased muscle definition and faster recovery
• Improved performance, energy, and fat loss
• Visible results often appear within 2–4 weeks of consistent use

Possible Side Effects

• Mild redness or irritation at injection site
• Potential for joint stiffness or hand tingling
• Rare: low blood sugar (hypoglycemia), bloating, or water retention

IGF-1 LR3 is a potent tool for body optimization and repair—make sure to work closely with your practitioner to use it safely and effectively.
