Cerebrolysin- Summary
- HGH Fragment 176-191 (also known as AOD-9604) is a stabilized, modified fragment of the human growth hormone molecule corresponding to amino acids 176–191 with an addition of a tyrosine residue at the N-terminus. It retains HGH's fat-burning properties without the anabolic, diabetogenic, or IGF-1-stimulating effects.
- 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.
