Eloralintide- Summary
- Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Gly) developed by Professor Vladimir Khavinson, tissue-specific for the testes. It supports Leydig cell function, normalization of testosterone biosynthesis, and spermatogenic activity. Testagen is used in men's health protocols for age-related testosterone decline, male fertility support, and testicular anti-aging.
- 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.

- Typical Dose
- 10 mg per day
- Under investigation in Phase 1/2 trials
- Frequency
- Daily for 10–30 days
- Once weekly
- Key Benefits
- Supports endogenous testosterone synthesis via Leydig cell normalization
- Promotes spermatogenesis and sperm quality
- Anti-aging effects on testicular tissue
- May attenuate age-related testosterone decline
- Mechanistically distinct from TRT — does not suppress HPG axis
- Useful adjunct to Gonadorelin and Kisspeptin-10 in male hormonal protocols
- Supports male fertility without exogenous hormone replacement
- 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
- Side Effects
- Generally well tolerated
- Mild injection site reactions
- No significant endocrine disruption reported at standard doses
- Nausea
- Vomiting
- Decreased appetite
- Injection site reactions
