IGF-1 LR3

What is Insulin-like Growth Factor 1, Long R3 Injection?

Insulin-like Growth Factor 1, Long R3 (IGF-1 LR3) is a synthetic peptide hormone classified as an injectable peptide in this 1 mg vial from Dragon Pharma. A modified version of natural IGF-1 with an extended half-life, it's used in bodybuilding for muscle growth and recovery, and in anti-aging for cellular repair. Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water, it has no hepatotoxicity, no aromatization, and minimal side effects when used responsibly.

Mechanism of Action IGF-1 LR3

IGF-1 LR3 binds to IGF-1 receptors, stimulating protein synthesis, cell proliferation, and hypertrophy in muscle tissues, promoting growth and repair. It enhances nutrient uptake and inhibits apoptosis, supporting anti-aging by maintaining cellular integrity. Users notice improved recovery, muscle fullness, and vitality within days to weeks.

With an extended half-life of approximately 20-30 hours (due to Long R3 modification), IGF-1 LR3 requires daily or every-other-day injections for optimal effects. It doesn't interact with androgenic or estrogenic pathways, ensuring no hormonal disruptions. What doesn't happen: no HPTA suppression, no water retention, and no liver toxicity, making it ideal for growth protocols.

Overuse may cause side effects like hypoglycemia, manageable with proper dosing and monitoring.

How It Works & Key Benefits

IGF-1 LR3 excels for bodybuilders and athletes seeking muscle growth and recovery, requiring a high-protein diet and training to maximize its anabolic effects.

• Promotes muscle growth and hypertrophy.
• Accelerates recovery from intense training.
• Enhances anti-aging and cellular repair.
• Improves nutrient uptake for performance.
• Supports joint and tissue health.
• Stacks effectively for comprehensive growth.

Who It's For & Product Specifications

Best for intermediate to advanced bodybuilders and athletes seeking muscle recovery, growth, or anti-aging benefits; suitable for men and women with careful dosing. Not recommended for those with peptide allergies or without injection knowledge.

How to Use

1. Dosage: 50-100 mcg/day, split into 1-2 doses; start at 50 mcg to assess tolerance.
2. Frequency: Daily via subcutaneous injection, preferably post-workout or evening.
3. Cycle length: 4-8 weeks, with breaks to avoid tolerance.
4. Preparation/Monitoring tips: Reconstitute with 1-2 ml bacteriostatic water; use insulin syringes; store refrigerated; monitor blood sugar and IGF-1 via labs; maintain high-protein diet.
5. Results timeline: Improved recovery in 1-2 weeks; muscle and anti-aging benefits in 4-6 weeks.
6. PCT timing: Not required as IGF-1 LR3 doesn't suppress hormones; align with steroid stack's PCT if combined (e.g., 3-4 days post-short ester).

Popular Stacks

CJC-1295: Synergizes for enhanced GH and IGF-1 release.

Testosterone Enanthate: Enhances muscle growth in anabolic cycles.

BPC-157: Supports localized tissue repair.

Cycle Support: Enhances overall health during intense protocols.

Comparisons & Alternatives

IGF-1 LR3 vs IGF-1 DES: LR3 has a longer half-life for systemic effects; DES is shorter-acting for localized muscle growth.

IGF-1 LR3 vs HGH: IGF-1 LR3 targets IGF-1 directly for muscle; HGH provides broader systemic benefits.

IGF-1 LR3 vs Insulin: IGF-1 LR3 promotes growth without severe hypoglycemia risk; Insulin is more potent but riskier.

Side Effects & Risk Management

• Systemic: Mild hypoglycemia—monitor blood sugar, eat carbs if needed.
• Dermatologic: Rare injection site redness—use sterile technique, rotate sites.
• Endocrine: None; no hormonal suppression.
• Cardiometabolic: None; no BP or lipid impact.
• Joint & Tendon: None; supports tissue health.

Review labs with a professional where lawful to ensure authenticity and proper dosing for safety.

Post-Cycle Therapy (PCT)

IGF-1 LR3 requires no PCT as it doesn't suppress testosterone or HPTA; align with steroid stack's PCT if combined (e.g., 3-4 days post-short ester). Use tamoxifen or clomiphene for 4 weeks if needed, guided by bloodwork.
