Epithalamin vs Retatrutide

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.

Retatrutide

Retatrutide is an investigational triple agonist targeting GIP, GLP-1, and glucagon receptors. Phase 2 trials showed unprecedented weight loss of up to 24% at 48 weeks, making it potentially the most effective obesity treatment studied.

Side-by-Side Comparison

AspectEpithalaminRetatrutide
MechanismSimilar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms.Triple receptor activation provides complementary metabolic effects: GLP-1 and GIP reduce appetite and improve insulin sensitivity, while glucagon receptor activation increases energy expenditure and promotes hepatic fat oxidation.
Typical DosageResearch dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols.Clinical trials used doses from 1mg to 12mg weekly. Optimal dosing still being determined in ongoing Phase 3 trials.
AdministrationIntramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon.Subcutaneous injection once weekly. Currently only available through clinical trials - not yet FDA approved.
Side EffectsGenerally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon.Similar GI effects to other incretin-based therapies: nausea, diarrhea, vomiting, constipation. Dose-dependent severity.
