Thymulin vs Ipamorelin
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 →Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Full details →Side-by-Side Comparison
| Aspect | Thymulin | Ipamorelin |
|---|---|---|
| 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, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones. |
| Typical Dosage | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. | Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. |
| Administration | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. |
| Side Effects | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. |
