Semax vs Zilucoplan (Zilbrysq)
An educational, source-based comparison of Semax and Zilucoplan (Zilbrysq) — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic heptapeptide derived from ACTH(4-10). Research suggests it modulates BDNF and NGF expression, dopaminergic and serotonergic tone, and shows neuroprotective effects in ischemia models.
- BDNF/NGF upregulation
- Ischemic stroke recovery (clinical use in Russia)
- Attention and cognitive performance
- Anxiolytic-style effects
- • Approved as a medication in Russia; not FDA-approved in the US.
- • Most clinical literature is in Russian.
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.
Semax vs Zilucoplan (Zilbrysq) — Key differences
- Class: Semax is classified as Nootropic · Neuroprotection, while Zilucoplan (Zilbrysq) is Complement Inhibitor · Neuromuscular.
- Primary research focus: Semax — bdnf/ngf upregulation; Zilucoplan (Zilbrysq) — generalized myasthenia gravis (anti-achr antibody positive).
- Tag: Cognition vs FDA-Approved · Neuromuscular.
