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 →HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | Selank | HGH Fragment 176-191 |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. |
| Typical Dosage | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
