AOD-9604 vs Thymulin

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

AOD-9604

AOD-9604 is a modified fragment of human growth hormone (HGH fragment 176-191). It was developed to have the fat-reducing effects of growth hormone without the adverse effects on blood sugar or growth.

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

AspectAOD-9604Thymulin
MechanismStimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat accumulation) without affecting blood sugar or growth. Works specifically on adipose tissue through a mechanism independent of GH receptors.Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age.
Typical DosageResearch dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg.Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range.
AdministrationSubcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity.
Side EffectsGenerally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.Limited data on exogenous administration. Theoretical effects on immune function require monitoring.
