What is IGF1 LR3?

IGF1 LR3 is an advanced and enhanced version of IGF-1 (insulin-like growth factor), developed to provide a much longer duration of action and a superior anabolic effect. Unlike natural IGF-1, which is active for only a few minutes, IGF1 LR3 can remain effective for up to 20–30 hours, promoting tissue growth and regeneration more significantly.

It is widely used in sports, regenerative medicine, and anti-aging to accelerate recovery, support muscle mass gain, and improve body composition. Thanks to its versatility, IGF1 LR3 can be easily integrated into protocols aimed at both performance and long-term well-being.

Main effects of IGF1 LR3

• 💪 Accelerated muscle growth: stimulates hypertrophy and hyperplasia (increase in size and number of fibers).

• 🛌 Faster recovery: improves post-workout cell regeneration.

• 📉 Fat reduction: supports metabolism and a leaner physique.

• 👶 Anti-aging action: benefits for skin, joints, and cognitive function.

• 🏃‍♂️ More energy and endurance: optimizes glucose utilization and cellular efficiency.

How to take IGF1 LR3

The product is supplied in a vial containing 1 mg of lyophilized powder and must be reconstituted with bacteriostatic water before use.

Recommended dosage

• Beginners: 20–40 mcg/day

• Experienced users: up to 80–100 mcg/day, if necessary

Diagram

• 1 injection per day (in the morning on an empty stomach or after training)

• Cycles of 2–6 weeks, with breaks of at least 4 weeks

Precautions

• Avoid overdoses (risk of changes in insulin sensitivity).

• Monitor blood sugar levels during prolonged use.

• Always use in cycles; not recommended during pregnancy, diabetes, or cancer.

How IGF1 LR3 works

• Activation of IGF-1 receptors: initiates signals for growth and tissue repair.

• mTOR and protein synthesis: boosts muscle protein synthesis.

• Muscle hyperplasia: promotes the formation of new fibers, a rare but highly beneficial event.

• Anti-catabolic action: preserves mass in conditions of stress or calorie deficit.

• Glucose management: improves glucose transport in tissues, supporting energy levels.

• Regeneration and rejuvenation: supports stem cells, blood flow, and joint health.

IGF-1 vs IGF1 LR3

• Structure: IGF1 LR3 is modified with additional amino acids for greater stability.

• Duration: Natural IGF-1 ~12–15 minutes; IGF-1 LR3 20–30 hours.

• Bioavailability: less binding to IGFBP → more pronounced effects.

• Results: IGF1 LR3 provides more intense stimulation of growth, recovery, and hyperplasia.

Storage

• Refrigerator 2–8 °C; do not freeze.

• Protect from light.

• After reconstitution, use within ~30 days.
