Mod GRF 1-29 vs Alpha-Defensin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Mod GRF 1-29
Mod GRF 1-29 (Modified GRF 1-29, also called CJC-1295 without DAC or Tetrasubstituted GRF 1-29) is a modified growth hormone-releasing hormone analog with improved stability over natural GHRH.
Full details →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.

| Aspect | Mod GRF 1-29 | Alpha-Defensin |
|---|---|---|
| Mechanism | Binds to GHRH receptors in the pituitary gland to stimulate growth hormone release. Four amino acid substitutions improve resistance to enzymatic degradation while maintaining biological activity. | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily, usually combined with a GHRP like Ipamorelin for synergistic effects. | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. |
| Administration | Subcutaneous injection. Best administered on empty stomach. Short half-life (~30 minutes) necessitates multiple daily doses, unlike DAC version. | Various routes studied including topical, local injection, and systemic administration depending on application. |
| Side Effects | Flushing, headache, dizziness, and injection site reactions. Generally well-tolerated. May cause water retention. | Limited human use data. May cause local inflammation. Potential for immune activation effects. |
