Epigen vs Teriparatide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epigen
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.

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.
Full details →Side-by-Side Comparison
| Aspect | Epigen | Teriparatide |
|---|---|---|
| Mechanism | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. | 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 | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. | 20mcg subcutaneously once daily. Maximum treatment duration of 2 years due to theoretical osteosarcoma risk from rat studies. |
| Administration | Primarily topical application for skincare. Research may use other routes for systemic effects. | 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 | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. | Orthostatic hypotension, leg cramps, nausea, dizziness, headache, and injection site reactions. Transient hypercalcemia possible. |
