Alpha-Defensin vs Human Growth Hormone (HGH)

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Alpha-Defensin

Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.

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.

Side-by-Side Comparison

AspectAlpha-DefensinHuman Growth Hormone (HGH)
MechanismInsert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation.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.
Typical DosageResearch compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use.Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher.
AdministrationVarious routes studied including topical, local injection, and systemic administration depending on application.Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated.
Side EffectsLimited human use data. May cause local inflammation. Potential for immune activation effects.Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses.
