IGF-LR3 10mg

IGF-1 LR3 – Prescription-Only Anabolic & Regenerative Peptide

Formulation: IGF-1 LR3 – 10 mg per vial
Classification: Prescription-Only Biologic Peptide – Requires Clinical Oversight, Baseline Labs, and Ongoing Provider Monitoring

What Is IGF-1 LR3?

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a recombinant peptide hormone that enhances the body’s natural growth and repair processes. The “Long Arg3” modification extends its half-life from approximately 20 minutes to over 20 hours, allowing for sustained anabolic and regenerative activity【Humbel RE, Eur J Biochem, 1990】.

IGF-1 LR3 is dispensed by prescription only and is used clinically for muscle growth, recovery optimization, and tissue healing under strict medical supervision.

How It Works

• Muscle Regeneration: Stimulates satellite cell activation and new muscle fiber formation (hyperplasia)【Adams GR et al., Am J Physiol Endocrinol Metab, 2002】.

• Connective-Tissue Repair: Promotes collagen synthesis and chondrocyte activity for joint, tendon, and ligament recovery【Ferry RJ et al., Endocr Rev, 1999】.

• Metabolic Enhancement: Improves glucose utilization and nutrient delivery to support recovery and energy balance【Fryburg DA et al., Am J Physiol, 1991】.

• Anti-Catabolic Support: Preserves lean tissue and reduces protein breakdown during intense training or caloric restriction【Bohé J et al., Am J Physiol Endocrinol Metab, 2001】.

Clinical Benefits

• Promotes lean muscle growth and strength gains

• Accelerates soft tissue healing and injury recovery

• Improves energy metabolism and insulin sensitivity

• Supports joint integrity and collagen remodeling

• Enhances synergy when combined with CJC-1295, Ipamorelin, or MOTS-C

Dosing Recommendations (in Units)

All dosing must be determined by your prescribing provider. The following represents a standard clinical framework for educational purposes.

• Typical Daily Dose: 10–20 units daily (equivalent to 20–40 mcg)

• Frequency: Once daily on training or active recovery days

• Timing: Immediately post-workout or in the morning on non-training days

• Cycle Duration: 4–8 weeks on, followed by 4 weeks off

• Administration: Subcutaneous injection into rotating sites (abdomen, thigh, or upper arm)

• Reconstitution Example:

  • Add 2 mL bacteriostatic water to 10 mg vial

  • Final concentration = 5,000 mcg/mL

  • 1 unit (on a 100-unit insulin syringe) = 50 mcg

  • 10 units = 500 mcg, 20 units = 1,000 mcg (1 mg)

  • Provider will adjust dilution to meet prescribed range

(Example concentrations vary; all dosing and dilution should follow provider instruction.)

Safety & Monitoring

Due to systemic growth and metabolic activity, IGF-1 LR3 should only be used under medical supervision with baseline and follow-up labs to monitor:

• Serum IGF-1 levels

• Glucose and insulin function

• Liver and renal markers

Potential side effects include mild hypoglycemia, localized swelling, or temporary joint stiffness—typically corrected through dose adjustment or timing modification.
