BPC-157 vs Human Growth Hormone (HGH) vs IGF-1 LR3
A three-way comparison to help you find the right peptide for your research goals.
BPC-157
Body Protection Compound-157 is a synthetic peptide derived from a protein found in human gastric juice. It has shown remarkable healing properties in research studies.
Full details →Human Growth Hormone (HGH)
Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.
Full details →IGF-1 LR3
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of IGF-1 with extended half-life and enhanced potency. The modifications prevent binding to IGF binding proteins, increasing bioavailability.

| Aspect | BPC-157 | Human Growth Hormone (HGH) | IGF-1 LR3 |
|---|---|---|---|
| Mechanism | BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels. | Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues. | Binds to IGF-1 receptors to promote protein synthesis, muscle growth, and fat metabolism. The LR3 modification (13 amino acid extension and arginine substitution) extends half-life from minutes to 20-30 hours. |
| Typical Dosage | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. | Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher. | Research protocols typically use 20-100mcg daily, often divided into multiple injections or administered bilaterally to target muscles. |
| Administration | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. | Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated. | Intramuscular injection (site-specific growth) or subcutaneous for systemic effects. Often cycled 4-6 weeks on, equal time off. |
| Side Effects | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. | Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses. | Hypoglycemia, joint pain, water retention, potential jaw/hand growth with extended use, and injection site reactions. |
