IGF-1 LR3 Research Protocols

Aug 27, 2025

Overview

This protocol outlines standard and advanced dosing, reconstitution, storage, and administration guidelines for IGF-1 LR3 (1mg vial) in research applications focused on muscle growth and recovery.

Dosing & Reconstitution Approaches

  • Standard protocol: 30–80 mcg daily, reconstituted to 3 mL (333 mcg/mL).
  • Advanced protocol: 50–120 mcg daily, reconstituted to 2 mL (500 mcg/mL).
  • Cycle duration is typically 8–12 weeks, with daily subcutaneous injections.
  • Reconstitute by adding bacteriostatic water slowly and gently swirling the vial.
  • Store lyophilized powder in the freezer; refrigerate after mixing and use within 30 days.

Dosing Schedule Examples

Standard / Gradual Approach (3 mL)

  • Weeks 1–2: ~33 mcg once daily (10 units).
  • Weeks 3–4: 50 mcg once daily (15 units).
  • Weeks 5–6: 66 mcg once daily (20 units).
  • Weeks 7–8: 80 mcg once daily (24 units).

Advanced / Aggressive Approach (2 mL)

  • Weeks 1–2: 50 mcg once daily (10 units).
  • Weeks 3–4: 75 mcg once daily (15 units).
  • Weeks 5–6: 100 mcg once daily (20 units).
  • Weeks 7–8: 120 mcg once daily (24 units).

Administration & Injection Technique

  • Use new, sterile insulin syringes for each injection.
  • Rotate subcutaneous injection sites (abdomen, thigh, etc.).
  • Clean stopper and injection site with alcohol swabs.
  • Inject at a 45–90 degree angle and do so slowly.

Supplies Needed

  • Peptide vials: 3–8 per cycle depending on length and dosage.
  • Insulin syringes: One per day (e.g., 56 for 8 weeks).
  • Bacteriostatic water and alcohol swabs.

Safety & Monitoring

  • Monitor for hypoglycemia and adverse reactions.
  • Track progress and adjust dosage if necessary.
  • Avoid repeated freeze-thaw cycles and consult a healthcare professional as needed.

Mechanism and Effects

  • IGF-1 LR3 is a long-acting analog of insulin-like growth factor 1.
  • May promote muscle, bone, and connective tissue growth and repair.
  • Supports protein synthesis and influences carbohydrate metabolism.
  • Potential side effects: hypoglycemia, joint pain, injection-site redness, or unwanted growth at high doses.

Recommendations / Advice

  • Always consult a qualified healthcare provider before starting or modifying any peptide protocol.
  • Pair protocol with protein-focused nutrition, strength training, recovery, sleep, and stress management for optimal results.
