Adamax- Summary
- Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
- 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.
- Half-Life
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- Estimated 1-3 hours (short; peptide degradation)
- Admin Route
- Oral
- Subcutaneous, Intranasal (research)
