Cerebrolysin- Summary
- GHRP-2 is a potent synthetic hexapeptide that stimulates growth hormone release by activating ghrelin receptors in the pituitary and hypothalamus. It produces one of the strongest GH pulses among GHRPs, though unlike Ipamorelin it does cause modest increases in cortisol and prolactin.
- Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
