Epithalamin vs GHRP-2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →GHRP-2
Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
Full details →Side-by-Side Comparison
| Aspect | Epithalamin | GHRP-2 |
|---|---|---|
| Mechanism | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. |
| Typical Dosage | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. |
| Administration | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. |
| Side Effects | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. |
