SHLP2 vs Thymulin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
SHLP2
SHLP2 (Small Humanin-Like Peptide 2) is a mitochondrial-derived peptide similar to humanin. It has shown insulin-sensitizing and cytoprotective effects in research, with potential metabolic benefits.

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.

| Aspect | SHLP2 | Thymulin |
|---|---|---|
| Dose Range | 1 mg–5 mg | 100 mcg–400 mcg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 4–8 weeks | 4–8 weeks |
| Route | subcutaneous | subcutaneous |
| Mechanism | Enhances insulin sensitivity and glucose uptake. Provides cytoprotective effects similar to humanin. May act through similar but distinct receptor pathways. | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. |
| Typical Dosage | Research compound with doses in the microgram to low milligram range studied in animal models. Human dosing not established. | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. |
| Administration | Subcutaneous or intraperitoneal injection in research settings. Various SHLP analogs (1-6) have different properties. | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. |
| Side Effects | Limited data. Animal studies suggest good tolerability. May affect glucose metabolism. | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. |
