Side-by-Side Comparison

AspectAlpha-DefensinDSIP
MechanismInsert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation.Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties.
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 30 minutes before sleep. Some protocols use it cyclically.
AdministrationVarious routes studied including topical, local injection, and systemic administration depending on application.Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.
Side EffectsLimited human use data. May cause local inflammation. Potential for immune activation effects.May cause grogginess upon waking, vivid dreams, or temporary headaches.
