Noopept vs Zilucoplan (Zilbrysq)
An educational, source-based comparison of Noopept and Zilucoplan (Zilbrysq) — how each peptide works, what it's researched for, and what to know before going deeper.
Dipeptide-derived nootropic researched for memory and neuroprotection.
A synthetic dipeptide (N-phenylacetyl-L-prolylglycine ethyl ester) derived from the endogenous nootropic cycloprolylglycine. Research suggests it potentiates AMPA receptor activity, increases BDNF and NGF expression, and provides antioxidant protection in neuronal tissue.
- Memory consolidation and retrieval
- Neuroprotection in ischemic injury
- Anxiety and emotional modulation
- Age-related cognitive decline
- • Approved in Russia; not FDA-approved in the US.
- • Generally well tolerated with few reported side effects.
Macrocyclic peptide complement C5 inhibitor for generalized myasthenia gravis.
A synthetic 15-amino-acid macrocyclic peptide that binds complement component C5 and blocks its cleavage to C5a/C5b, preventing formation of the membrane attack complex at the neuromuscular junction. Self-administered subcutaneously.
- Generalized myasthenia gravis (anti-AChR antibody positive)
- • FDA-approved 2023.
- • Requires meningococcal vaccination — risk of serious meningococcal infection.
- • Injection-site reactions common.
Trial-evidence rating
Educational grade reflecting how many peer-reviewed studies and FDA actions we cite for each peptide. Not a clinical recommendation.
