IGF-1 LR3 is a synthetic variant of IGF-1 modified for greater potency and longer half-life. The Long R3 substitution reduces binding to IGF-binding proteins (IGFBPs), increasing bioavailability at the receptor level. Key actions include:

• Anabolic Signaling: Binds the IGF-1 receptor and activates PI3K-Akt-mTOR pathways to promote protein synthesis and inhibit proteolysis, driving hypertrophy and tissue repair.

• Recovery & Performance: Supports satellite-cell activity and connective-tissue remodeling for quicker turnaround between sessions.

• Body Recomposition: May support fat metabolism while preserving lean mass under structured training and nutrition.

This is a research-grade peptide; responses depend on protocol design, baseline status, and study conditions.

• Reconstitution: Reconstitute with Bacteriostatic Water (3 mL recommended). Add slowly and swirl gently do not shake.

• Specifications: Lyophilized powder; purity >98%, meets or exceeds U.S. Pharmacopeia (USP) regulations.

• Storage:

  • Lyophilized: Stable for 2 years; protect from light.

  • After reconstitution: Refrigerate (2–8 °C) and use within 45 days of opening/reconstitution.

• Best Practices: Handle on a clean surface using aseptic technique and gloves to avoid contamination.
