Semaglutide vs Dermorphin
Side-by-side comparison of key properties, dosing, and research.
GLP-1 / Weight Loss Agonists
SemaglutideRecovery & Repair
Dermorphin- Summary
- Semaglutide is an FDA-approved GLP-1 receptor agonist originally developed for type 2 diabetes that has proven remarkably effective for weight loss. Clinical trials show average 15–20% body weight reduction. It is marketed as Ozempic (diabetes) and Wegovy (weight management).
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Half-Life
- ~7 days
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Admin Route
- SubQ, Oral
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
