Thymulin vs Hexarelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymulin
Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.
Full details →Hexarelin
Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.

| Aspect | Thymulin | Hexarelin |
|---|---|---|
| Mechanism | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. | Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling. |
| Typical Dosage | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. | Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization. |
| Administration | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. | Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols. |
| Side Effects | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. | Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects. |
