Main Information

IGF-1 LR3 is a long-acting analog of insulin-like growth factor-1 engineered for higher stability and receptor activity. It supports lean muscle growth, accelerates recovery, and promotes tissue repair by enhancing protein synthesis and nutrient uptake. Suitable for advanced performance and regeneration protocols when precise dosing and monitoring are available.

Scientific Background

GF-1 is one of the main messengers through which growth hormone works. It helps the body build new muscle proteins, repair muscle fibers, and activate “satellite cells” that are essential for growth and recovery.The LR3 form of IGF-1 has been modified to last longer in the body and to stay active instead of being quickly bound and neutralized. This means it can provide a stronger and more consistent anabolic (muscle-building) effect.

With these properties, IGF-1 LR3 not only supports muscle growth and recovery but also helps with tendon and soft tissue repair and may reduce the damage caused by intense exercise. Because it can also affect blood sugar levels in an insulin-like way, protocols need to be carefully designed and monitored.

Usage Instructions

You find the most important facts concerning usage below. For detailed guidance on preparation, administration, and dosage of your product, please refer to the product leaflet provided with your package or at the bottom of this page.

Administration route: Subcutaneous (preferred) or intramuscular
Needle size: 29–31G (subQ) or 25–27G (IM)
Preparation: Reconstitute lyophilized vial with bacteriostatic water; swirl gently, do not shake
Storage: Lyophilized at −20 °C; after reconstitution 2–8 °C, protected from light
Timing: Post-training or morning; maintain consistent timing across a cycle
Glucose note: Monitor carbohydrate intake and be alert for hypoglycemia-like symptoms due to insulin-like activity

Dosage Information

Final microgram (µg) amounts depend on concentration per vial; adjust volume accordingly. Start conservatively and titrate by response.

Performance & Hypertrophy Protocol (Advanced Users)

20–40 µg per day, 5 days on / 2 off, for 4–6 weeks
Post-training or split AM/PM (even split doses)

Localized Recovery / Rehab Support

20–30 µg per day, 5 days/week for 3–4 weeks

Consider site-specific administration near target muscle group (research context)

Deload / Maintenance

20 µg every other day for 2–3 weeks following a higher-intensity block

Important Warnings

Research use only; not for clinical treatment.
Do not exceed suggested ranges without qualified supervision.
Use caution in individuals with glucose dysregulation, neoplasia risk, or active proliferative conditions.
Potential effects: headache, fatigue, injection-site irritation; rare: hypo-like symptoms (sweats, tremor, dizziness).
Discontinue and seek medical advice if you experience severe edema, vision changes, palpitations, or allergic reactions.
Sterile technique required; rotate injection sites; do not reuse needles/syringes.
Not recommended during pregnancy or breastfeeding.
