IGF-1 LR3 – 1mg
$100.00
Overview:
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a potent growth peptide designed to amplify muscle growth, recovery, and fat metabolism. It offers enhanced bioavailability and a much longer half-life than natural IGF-1.
Uses: Perfect for lean bulking, muscle hardening, and accelerated recovery phases. Often used by advanced athletes looking to push past plateaus in size and strength.
Stacking: Works synergistically with HGH, insulin (advanced users only), or peptides like CJC-1295 or Ipamorelin for max anabolic effect.
Benefits:
-
Increases lean muscle growth
-
Enhances nutrient partitioning and fat loss
-
Promotes hyperplasia (more muscle cells)
-
Speeds up recovery and injury repair
Dosage: Supplied in a 1mg vial. Typical dose ranges from 20–100mcg per day. Inject once daily post-workout or first thing in the morning, subcutaneously or intramuscularly. Most users run it for 4–6 weeks.
What is IGF-1 LR3?
IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor 1) is a modified version of natural IGF-1, designed to be more stable and effective. By replacing arginine at position 3 and extending the amino acid chain, this version has a half-life of around 20–30 hours—making it significantly more potent and longer-lasting than natural IGF-1.
Mechanism of Action:
IGF-1 LR3 stimulates muscle growth by binding to the IGF-1 receptor, activating cellular proliferation and differentiation. Its primary role in the body is to mediate the anabolic effects of growth hormone—especially by encouraging hyperplasia (creation of new muscle cells), not just hypertrophy (enlarging existing ones). This makes it extremely effective for long-term gains.
Key Benefits:
Muscle Hyperplasia: Unlike steroids, which increase muscle size, IGF-1 LR3 can increase the number of muscle fibers, offering a whole new level of growth potential.
Improved Recovery: Speeds up recovery by stimulating tissue regeneration at a cellular level.
Fat Burning: IGF-1 enhances nutrient partitioning and glucose uptake, making it easier to stay lean while building size.
Enhanced Pumps: Increased cell volumization leads to tighter, fuller muscles during and after workouts.
Joint & Tendon Support: Promotes healing of connective tissue and may support long-term joint health.
Stacking:
With HGH: A highly synergistic combination, especially when HGH is taken in the morning and IGF-1 post-training.
With Peptides: Stack with CJC-1295 DAC, Ipamorelin, or GHRP-2/6 for natural GH release and amplified IGF-1 response.
Advanced Stack: Some high-level users incorporate insulin (only if experienced and properly educated) for elite-level size gains.
Dosage & Administration:
Vial Content: 1mg lyophilized powder
Reconstitution: Mix with 1ml–2ml of bacteriostatic water
Typical Dose: 20mcg to 100mcg per day
Beginners: 20–40mcg
Intermediate/Advanced: 50–100mcg
Injection Timing: Best used post-workout or first thing in the morning
Injection Type: Subcutaneous or intramuscular (usually in a rotating site)
Cycle Length: 4–6 weeks on, followed by 4+ weeks off
Side Effects:
Mild Hypoglycemia: Especially when stacked with insulin or at higher doses
Injection site irritation (rare)
Headaches or fatigue (usually at high doses)
No suppression of testosterone or estrogen – PCT not required
Best Use Cases:
Lean mass gaining phases
Breaking growth plateaus
Post-injury recovery and muscle preservation
Athletic performance enhancement
Cosmetic fullness and density for bodybuilders pre-show
