Eloralintide- Summary
- Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
- Eloralintide is a long-acting amylin analog under development by OPKO Health. Amylin is co-secreted with insulin and regulates post-meal glucose by slowing gastric emptying, suppressing glucagon, and promoting satiety. Eloralintide is designed for once-weekly dosing, differentiating it from the short-acting pramlintide (Symlin). It is being studied for obesity and type 2 diabetes as a complement to GLP-1 based therapies.
- Half-Life
- ~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
- ~7 days (estimated, long-acting design)

- Typical Dose
- 100 mcg
- Under investigation in Phase 1/2 trials
- Frequency
- Twice daily (every 12 hours)
- Once weekly
- Key Benefits
- Maintains testicular size during TRT
- Preserves fertility and sperm production during testosterone use
- Stimulates endogenous LH/FSH production
- Maintains HPG axis function during exogenous hormone use
- Used for HCG-free TRT protocols
- Helps restart natural testosterone production (PCT)
- Once-weekly dosing (vs multiple daily injections for pramlintide)
- Appetite suppression via central amylin receptor activation
- Reduction in post-meal glucagon secretion
- Complementary mechanism to GLP-1 agonists for combination therapy
- Slows gastric emptying for prolonged satiety
- Potential additive weight loss when combined with GLP-1 agents
