IGF-1 LR3

IGF-1 LR3 is a synthetic 83-amino acid analog of human insulin-like growth factor-1 that has never been approved for human use in any country. Despite approximately 3x greater potency than native IGF-1 with a 20-30 hour half-life due to reduced IGF-binding protein interaction, no human clinical trials have ever been conducted. The compound is prohibited in competitive sports, carries significant risks including severe hypoglycemia and cancer proliferation, and remains strictly a research chemical for laboratory use only.

• Muscle Hypertrophy
• Anti-Catabolic Effects
• Hyperplasia Induction

Approximately 3x more potent than native IGF-1 with 20-30 hour half-life due to reduced IGFBP binding. Promotes both muscle hypertrophy and hyperplasia in animal models.

Full IGF-1 receptor agonist with reduced IGF-binding protein interaction. N-terminal extension and R3 substitution prevent sequestration, maintaining free circulating levels. Activates PI3K/Akt/mTOR and MAPK/ERK pathways.

Research protocols from published literature — not dosing recommendations.

• Human Growth Hormone — Avoid Combination: Creates excessive IGF-1 levels. HGH already elevates endogenous IGF-1, adding exogenous LR3 amplifies cancer risk and organ hypertrophy.
• CJC-1295/Ipamorelin — Use Caution: Both stimulate GH/IGF-1 axis. Combined use may cause receptor desensitization and compounded metabolic effects.
• MK-677 — Monitor Combination: MK-677 increases endogenous IGF-1. Monitor for joint pain, water retention, and insulin sensitivity disruption.
• Insulin — Avoid Combination: Synergistic hypoglycemic effects can be life-threatening. Requires professional medical supervision if combined.
• BPC-157 — Synergistic: Popular healing stack. BPC-157 (250-500mcg 2x daily) with IGF-1 LR3 (40-60mcg daily) may accelerate tissue repair.
• TB-500 — Synergistic: Complementary healing mechanisms. TB-500 (2-5mg weekly) with IGF-1 LR3 enhances recovery through different pathways.
• Anabolic Steroids — Use Caution: Amplified anabolic effects but substantially increased health risks including organ hypertrophy and metabolic dysfunction.
• Metformin — Dose Dependent: May help mitigate insulin resistance from chronic IGF-1 use, but requires blood glucose monitoring and dose adjustment.
• Cerebrolysin — Monitor Combination: Both affect growth factor pathways and neuroplasticity. IGF-1 LR3 binds IGF-1 receptors while Cerebrolysin enhances BDNF/NGF. Potential for additive neurotrophic effects - use conservative doses and monitor for signs of excessive stimulation.

Supplies:

• 0.6% Acetic Acid (maximum stability)
• OR Bacteriostatic Water (7-day stability only)
• 29-32 gauge insulin syringes
• Alcohol swabs
• Sterile vial

1. 1Equilibrate vial to room temperature (15-30 min)
2. 2Sanitize rubber stopper with alcohol
3. 3Calculate concentration (e.g., 1mg in 2mL = 500mcg/mL)
4. 4Draw calculated volume of solution
5. 5Inject slowly along vial wall, not directly on powder
6. 6Gently swirl - never shake vigorously
7. 7Allow to dissolve completely (2-5 min)
8. 8Store immediately at 2-8°C protected from light

Week 1-2: Increased pump, fullness, possible hypoglycemia episodes if carbs inadequate. Week 2-4: Enhanced recovery, strength gains, visible muscle fullness, possible water retention. Week 4-6: Maximum effects but approaching receptor desensitization. Joint stiffness common.. Post-cycle: Gradual loss of pumps over 1-2 weeks. Strength/size gains may persist if training maintained..

CRITICAL: Consume 30-60g fast carbohydrates immediately after injection. Never inject before sleep - overnight hypoglycemia risk. Monitor blood glucose regularly, especially first week. Contraindicated with any cancer history or undiagnosed growths. May cause organ hypertrophy (heart, intestines) with prolonged use. WADA prohibited - will cause failed drug test in athletes.

IGF-1 LR3 should be stored at Lyophilized: -20°C long-term. Reconstituted in acetic acid: 2-8°C up to 1 year. In bac water: 7 days max..
