What is Semax?
Unlike full ACTH, Semax retains the region associated in the literature with effects on the nervous system, without the hormonal activity on the adrenal glands. Because of its profile it is classified as a nootropic peptide, and in research it is linked to neurotrophic factors such as BDNF.
Research context
The preclinical literature on Semax has explored its relationship with cognition, attention and neuroprotection in animal models.
These findings belong to the field of research and do not constitute evidence of efficacy in humans. Semax is offered for research use only.
