IGF-1 LR3 by Dragon Pharma contains Insulin-like Growth Factor 1, Long R3, a synthetic peptide designed to enhance muscle growth, accelerate recovery, and improve performance. Each vial provides 1 mg of lyophilized powder for injection, ideal for bodybuilders aiming for lean muscle gains and enhanced physique. With an extended half-life of 20–30 hours compared to natural IGF-1, IGF-1 LR3 delivers sustained anabolic effects for optimal results.
What It Is
IGF-1 LR3 is a modified version of Insulin-like Growth Factor 1, with a longer half-life due to its Long R3 structure, which resists binding to IGF-binding proteins. Naturally produced in the liver in response to growth hormone (GH), IGF-1 promotes cell growth and repair. In bodybuilding, IGF-1 LR3 is used to enhance muscle hypertrophy, recovery, and fat metabolism, offering a targeted approach to performance enhancement without direct GH administration.
How It Works
IGF-1 LR3 binds to IGF-1 receptors, stimulating protein synthesis and muscle cell proliferation (hyperplasia). It enhances nutrient uptake into muscle cells, promoting growth and repair while inhibiting muscle breakdown. Its long half-life ensures prolonged activity, amplifying anabolic effects compared to natural IGF-1. IGF-1 LR3 also supports fat metabolism and connective tissue repair, making it a versatile peptide for bodybuilding and recovery.
Benefits
- Muscle Growth: Promotes hypertrophy and hyperplasia for lean muscle gains.
- Faster Recovery: Accelerates muscle and tissue repair post-workout.
- Fat Loss: Enhances fat metabolism for a leaner physique.
- Strength Gains: Improves power and performance in training.
- Connective Tissue Support: Strengthens tendons and ligaments.
Who It's For
IGF-1 LR3 is ideal for male and female bodybuilders aged 21–40 seeking muscle growth, recovery, and fat loss in bulking or cutting cycles. It's suitable for intermediate to advanced users familiar with peptides. Not for: Individuals under 21, those with diabetes or insulin-related conditions, or those not under medical supervision. Blood work to monitor IGF-1 levels and glucose is recommended.
How to Use
Dosage: Typical dosage is 20–100 mcg/day, injected intramuscularly or subcutaneously. Beginners should start at 20–40 mcg/day to assess tolerance, increasing to 50–100 mcg/day if needed. Women may use lower doses (20–50 mcg/day).
Administration: Reconstitute the 1 mg vial with 1–2 ml bacteriostatic water. Draw 0.02–0.1 ml (20–100 mcg) into a 0.5-inch insulin syringe (27–30G) and inject intramuscularly (near the target muscle, e.g., biceps) or subcutaneously (e.g., abdomen). Administer post-workout or on an empty stomach for optimal absorption. Cycles typically last 4–6 weeks, followed by a 4–6 week break to prevent receptor desensitization.
Results Timeline: Muscle growth and recovery improvements are noticeable within 1–2 weeks, with significant lean muscle gains and fat loss by 4–6 weeks when paired with a high-protein diet and training.
Stacking Suggestions
IGF-1 LR3 is highly effective in stacks:
- Bulking Stack: Combine with CJC-1295 (100–200 mcg/day) or HGH (2–4 IU/day) for amplified muscle growth and GH synergy.
- Cutting Stack: Pair with Cardarine (10–20 mg/day) for enhanced fat loss and endurance.
- Support: Use with BPC-157 (250–500 mcg/day) for synergistic tissue repair and recovery.
Side Effects
IGF-1 LR3 is generally well-tolerated but may cause:
- Hypoglycemia: Low blood sugar, especially at higher doses; monitor glucose and avoid fasting.
- Injection Site Reactions: Mild redness or swelling; rotate sites.
- Joint Pain: Temporary, linked to rapid tissue growth.
- Water Retention: Rare, dose-dependent; adjust dosage if occurs.
Regular blood work to monitor IGF-1, glucose, and liver function is recommended. Avoid overuse to prevent long-term risks.
Post Cycle Therapy (PCT)
IGF-1 LR3 does not suppress testosterone, so PCT is not required unless stacked with anabolic steroids. If stacked with suppressive compounds, use Clomid (50 mg/day) and Nolvadex (20–40 mg/day) for 4–6 weeks post-cycle. Take a 4–6 week break between IGF-1 LR3 cycles to maintain receptor sensitivity.
Warnings / Disclaimer
IGF-1 LR3 is intended for research purposes only unless prescribed by a licensed physician. It is not suitable for individuals under 21, those with diabetes or insulin-related conditions, or those not under medical supervision. Regular blood work to monitor IGF-1, glucose, and liver function is essential. Store unreconstituted vials at 2–8°C and reconstituted vials in a refrigerator, away from children.
Frequently Asked Questions
Is IGF-1 LR3 better than HGH?
IGF-1 LR3 directly promotes muscle growth and recovery with a longer half-life (20–30 hours) than HGH, but HGH stimulates broader systemic effects via natural IGF-1 production. IGF-1 LR3 is better for targeted muscle gains, while HGH is more versatile for overall growth and anti-aging. Choice depends on goals and budget.
Does IGF-1 increase testosterone?
IGF-1 LR3 does not directly increase testosterone but supports anabolic processes that may indirectly enhance testosterone's effects by improving muscle growth and recovery. It has no significant impact on the hypothalamic-pituitary-gonadal axis.
What are the benefits of IGF-1 peptides?
IGF-1 peptides like LR3 promote muscle growth (hypertrophy and hyperplasia), accelerate recovery, enhance fat loss, improve strength, and support connective tissue repair, making them ideal for bodybuilding and performance enhancement.
What does IGF-1 do to your body?
IGF-1 LR3 stimulates protein synthesis, promotes muscle cell growth, enhances fat metabolism, accelerates tissue repair, and strengthens connective tissues, leading to improved muscle mass, recovery, and a leaner physique.
