Human Growth Hormone (HGH) vs Lactoferricin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

| Aspect | Human Growth Hormone (HGH) | Lactoferricin |
|---|---|---|
| Mechanism | 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 and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. |
| Typical Dosage | 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 applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. |
| Administration | Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated. | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. |
| Side Effects | Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses. | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. |
