Side-by-Side Comparison

AspectAlpha-DefensinGHRP-2
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 the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6.
Typical DosageResearch compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use.Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release.
AdministrationVarious routes studied including topical, local injection, and systemic administration depending on application.Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep.
Side EffectsLimited human use data. May cause local inflammation. Potential for immune activation effects.Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations.
