HD Labs - IGF1LR3 Kit 100mcg (10 vials)

IGF-1 LR3 is a synthetic version of human insulin-like growth factor 1 with an extended half-life, designed to remain active in the body longer than natural IGF-1. This peptide plays a crucial role in muscle regeneration, nutrient uptake, and cellular repair. It works by promoting protein synthesis, improving nitrogen retention, and stimulating satellite cell proliferation, which helps build new muscle fibers. IGF-1 LR3 is widely used by bodybuilders, athletes, and individuals looking to improve muscle quality, reduce fat, and recover faster from intense training. Its ability to enhance nutrient delivery also supports lean muscle gain without significant water retention.

Benefits:

• Stimulates new muscle cell growth and repair

• Enhances protein synthesis and nutrient absorption

• Promotes fat loss while preserving lean muscle

• Improves recovery and performance

• Increases muscle fullness and vascularity

Side Effects:

• Mild hypoglycemia (low blood sugar)

• Temporary headaches or fatigue

• Injection site irritation

• Rare water retention or joint discomfort at higher doses

Dosages & Protocol:
Beginners: 20–40mcg daily (0.02–0.04mg = 0.1–0.2ml)
Intermediate: 40–60mcg daily (0.04–0.06mg = 0.2–0.3ml)
Advanced: 60–100mcg daily (0.06–0.1mg = 0.3–0.5ml), split into 2 doses—morning and post-workout—for best results

Administer on an empty stomach to enhance absorption. Combine with proper nutrition and resistance training to maximize results.

How to Administer:
Reconstitute the IGF-1 LR3 vial by adding 1ml of bacteriostatic water into the vial. Swirl gently until the powder dissolves completely—do not shake. Inject subcutaneously (under the skin) into the abdomen or thigh using an insulin syringe. Rotate injection sites with each dose to avoid irritation.

Storage:
Store the lyophilized (dry) vial in a cool, dark place. Once reconstituted, refrigerate between 2–8°Cand use within 30 days.

Half-Life & Detectability:
Half-life: Approximately 20–30 hours
Detection time: Up to 24–48 hours
For athletes subject to drug testing, it is important to consider these detection times and plan accordingly to avoid positive tests for banned substances.
