Thymalin vs Dulaglutide

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

Thymalin

Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

Dulaglutide

Dulaglutide (Trulicity) is a once-weekly GLP-1 receptor agonist for type 2 diabetes. Its larger molecular size from fusion with an Fc fragment extends half-life and may reduce some GI side effects.

Side-by-Side Comparison

AspectThymalinDulaglutide
MechanismRegulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production.GLP-1 analog fused to a modified human IgG4 Fc fragment, providing extended duration of action. Activates GLP-1 receptors for glucose-dependent insulin secretion and appetite suppression.
Typical DosageClinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance.Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response.
AdministrationIntramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols.Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens.
Side EffectsGenerally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated.Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration.
