Selank vs Dulaglutide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Selank
Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement.
Full details →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.

| Aspect | Selank | Dulaglutide |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | 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 Dosage | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration. |
