Cerebrolysin vs Teriparatide

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.

Teriparatide

Teriparatide (Forteo) is recombinant human parathyroid hormone (1-34), FDA-approved for osteoporosis treatment. It's unique among osteoporosis drugs in that it stimulates new bone formation.

Side-by-Side Comparison

Aspect	Cerebrolysin	Teriparatide
Dose Range	2150 mg–4300 mg	20 mcg
Frequency	1x daily	1x daily
Cycle Length	1–2 weeks	52–104 weeks
Route	intramuscular	subcutaneous
Mechanism	Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties.	Intermittent PTH exposure paradoxically stimulates osteoblasts more than osteoclasts, resulting in net bone formation. Continuous exposure would cause bone loss, but pulsatile dosing builds bone.
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.	20mcg subcutaneously once daily. Maximum treatment duration of 2 years due to theoretical osteosarcoma risk from rat studies.
Administration	Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes.	Subcutaneous injection in thigh or abdomen once daily. Delivered via multi-dose pen. Should sit or lie down after injection due to orthostatic hypotension risk.
Side Effects	Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.	Orthostatic hypotension, leg cramps, nausea, dizziness, headache, and injection site reactions. Transient hypercalcemia possible.
