Calculate IGF-1 LR3 Decay

Key Takeaways: IGF-1 LR3

IGF-1 LR3 is a Other peptide primarily researched for:

  • Superior muscle growth (Hyperplasia)
  • Long-acting half-life (20-30 hours)
  • Improved metabolic rate and fat loss

Freezable? ❌ No (Fragile)

IGF-1 LR3 (Long Arginine 3 IGF-1) is a synthetic, long-acting analog of the human hormone Insulin-like Growth Factor 1. It is designed to be significantly more potent and stable than natural IGF-1.

Extended Half-Life

By modifying the peptide structure, IGF-1 LR3 avoids being neutralized by IGF-binding proteins in the blood. This extends its activity from a few minutes to over 24 hours, allowing it to exert powerful anabolic effects on muscle and organ tissue throughout the day.

Hyperplasia vs Hypertrophy

Researchers are particularly interested in IGF-1 LR3 because it can stimulate hyperplasia—the creation of new muscle cells—rather than just hypertrophy (making existing cells larger). This makes it a primary focus for research into muscle wasting and regenerative medicine.

Key Benefits

  • Superior muscle growth (Hyperplasia)
  • Long-acting half-life (20-30 hours)
  • Improved metabolic rate and fat loss
  • Enhanced tissue and nerve repair

Potential Side Effects

  • Hypoglycemia (if not managed)
  • Injection site swelling
