IGF-1 LR3 1 mg

IGF-1 LR3 1 mg – Peptide for Growth and Muscle Recovery

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic peptide known for its ability to support lean muscle growth, recovery, and cellular repair. This extended version of natural IGF-1 has a longer half-life, providing greater bioavailability and longer activity in the body. Peptide Hubs offers this research-grade peptide in a 2 mL vial containing 1 mg of IGF-1 LR3.

What Makes IGF-1 LR3 Unique?

IGF-1 LR3 is engineered to resist binding to IGF-binding proteins (IGFBPs), allowing it to remain active for up to 20–30 hours. As a result, it promotes muscle cell proliferation and tissue repair more effectively than standard IGF-1. According to research published in the Journal of Molecular Endocrinology, IGF-1 plays a pivotal role in muscle regeneration and satellite cell activation.

Benefits of IGF-1 LR3 1 mg

• Enhances muscle growth and strength
• Speeds up recovery after intense training
• Stimulates cellular repair and regeneration
• Improves fat metabolism and nutrient partitioning
• Supports anti-aging and neuroprotective research

Researchers often combine this peptide with Ipamorelin or CJC-1295 DAC to stimulate endogenous GH levels for a synergistic effect.

Suggested Research Protocol

In research contexts, IGF-1 LR3 is typically administered via subcutaneous or intramuscular injection at doses ranging from 20 to 100 mcg per day. Protocols often last 2–4 weeks. For enhanced healing, it may be stacked with BPC-157 or GHK-CU.

Buy from a Trusted Peptide Source

Although this peptide does not currently include a published lab test, it is sourced from a reliable research-grade supplier with a reputation for purity and consistency in peptide formulation.

Recommended Stacks with IGF-1 LR3
