Sermorelin & GHRP-2 & GHRP-6 vs Epithalamin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

| Aspect | Sermorelin & GHRP-2 & GHRP-6 | Epithalamin |
|---|---|---|
| Mechanism | 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. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | 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. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Subcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | Increased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
