Mod GRF 1-29 vs Pinealon
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 →Pinealon
Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies.

| Aspect | Mod GRF 1-29 | Pinealon |
|---|---|---|
| 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. | Penetrates cell membranes and interacts with DNA to regulate gene expression related to neuronal survival and function. May support pineal gland function and melatonin production. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily, usually combined with a GHRP like Ipamorelin for synergistic effects. | Typical dosing: 10-20mg daily, taken in divided doses. Often used in cycles of 10-20 days. |
| Administration | Subcutaneous injection. Best administered on empty stomach. Short half-life (~30 minutes) necessitates multiple daily doses, unlike DAC version. | Can be taken orally (capsules) or sublingually. Best absorbed on an empty stomach. Often combined with other neuroprotective peptides. |
| Side Effects | Flushing, headache, dizziness, and injection site reactions. Generally well-tolerated. May cause water retention. | Generally well-tolerated. Limited reported side effects. May affect sleep patterns initially. |
