Ipamorelin vs Thymulin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

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.

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.

Side-by-Side Comparison

AspectIpamorelinThymulin
MechanismActs 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.Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age.
Typical DosageTypical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295.Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range.
AdministrationSubcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides.Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity.
Side EffectsGenerally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially.Limited data on exogenous administration. Theoretical effects on immune function require monitoring.
