GHRP-6 vs Alpha-Defensin

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

GHRP-6

Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.

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.

Side-by-Side Comparison

AspectGHRP-6Alpha-Defensin
MechanismActs as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects.Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation.
Typical DosageTypical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects.Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use.
AdministrationSubcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting.Various routes studied including topical, local injection, and systemic administration depending on application.
Side EffectsIntense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes.Limited human use data. May cause local inflammation. Potential for immune activation effects.
