Epitalon vs Teriparatide
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.

Teriparatide (Forteo) is recombinant human parathyroid hormone (1-34), FDA-approved for osteoporosis treatment. It's unique among osteoporosis drugs in that it stimulates new bone formation.

| Aspect | Epitalon | Teriparatide |
|---|---|---|
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Intermittent PTH exposure paradoxically stimulates osteoblasts more than osteoclasts, resulting in net bone formation. Continuous exposure would cause bone loss, but pulsatile dosing builds bone. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | 20mcg subcutaneously once daily. Maximum treatment duration of 2 years due to theoretical osteosarcoma risk from rat studies. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Subcutaneous injection in thigh or abdomen once daily. Delivered via multi-dose pen. Should sit or lie down after injection due to orthostatic hypotension risk. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Orthostatic hypotension, leg cramps, nausea, dizziness, headache, and injection site reactions. Transient hypercalcemia possible. |
