Epitalon vs GHRP-2

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Epitalon

Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.

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.

Side-by-Side Comparison

Aspect	Epitalon	GHRP-2
Dose Range	5 mg–10 mg	100 mcg–300 mcg
Frequency	1x daily	3x daily
Cycle Length	2–3 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
Mechanism	Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production 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	Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.	Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release.
Administration	Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.	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 initially.	Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations.
Best For	Sleep Quality	Muscle Growth Fat Loss Sleep Quality
