Alpha-Defensin vs Sermorelin & GHRP-2 & GHRP-6
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.
Full details →Sermorelin & GHRP-2 & GHRP-6
A powerful tri-blend combining Sermorelin (a GHRH analog) with two growth hormone releasing peptides. This combination produces significantly greater GH release than any single peptide, with studies showing up to 54-fold increases in pulsatile GH secretion.

| Aspect | Alpha-Defensin | Sermorelin & GHRP-2 & GHRP-6 |
|---|---|---|
| Mechanism | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. | Sermorelin stimulates the pituitary via GHRH receptors, while GHRP-2 and GHRP-6 act as ghrelin mimetics on different receptor subtypes. The combination creates synergistic GH release through multiple complementary pathways. GHRP-6 also strongly stimulates appetite. |
| Typical Dosage | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. | Typical protocols: Sermorelin 100-300mcg, GHRP-2 100-300mcg, GHRP-6 100-300mcg. Often administered 2-3 times daily, 30 minutes before meals or at bedtime. |
| Administration | Various routes studied including topical, local injection, and systemic administration depending on application. | Subcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately. |
| Side Effects | Limited human use data. May cause local inflammation. Potential for immune activation effects. | Increased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels. |
