Adamax vs Semax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Adamax is a synthetic neuropeptide related to brain-derived neurotrophic factor (BDNF) signaling pathways. It is explored for cognitive enhancement, neuroprotection, and mood support, with proposed mechanisms involving TrkB receptor activation and enhancement of neuroplasticity similar to endogenous BDNF.
- Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
- Half-Life
- Estimated 1-3 hours (short; peptide degradation)
- Minutes (but effects persist for hours via BDNF induction)
- Admin Route
- Subcutaneous, Intranasal (research)
- Intranasal, SubQ
