Cerebrolysin vs Pramlintide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia.
Full details →Pramlintide
Pramlintide (Symlin) is a synthetic analog of amylin, FDA-approved as an adjunct to insulin therapy in type 1 and type 2 diabetes. It helps control post-meal blood sugar spikes and promotes modest weight loss.

| Aspect | Cerebrolysin | Pramlintide |
|---|---|---|
| Mechanism | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. | Mimics amylin's effects: slows gastric emptying, suppresses glucagon secretion after meals, and promotes satiety through central mechanisms. Complements insulin therapy. |
| Typical Dosage | Clinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days. | Type 1: Start 15mcg before meals, titrate to 30-60mcg. Type 2: Start 60mcg, may increase to 120mcg. Always with meal containing 30+ grams carbs or 250+ calories. |
| Administration | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. | Subcutaneous injection immediately before major meals. Must reduce mealtime insulin by 50% when starting to prevent hypoglycemia. Never mix with insulin. |
| Side Effects | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. | Nausea (very common initially), headache, anorexia, vomiting, and abdominal pain. GI effects typically improve over time. |
