What is Selank?
Selank is a tuftsin analog designed to be more stable. In the literature it is classified as a peptide with anxiolytic and nootropic properties, and it is linked to the modulation of neurotransmitters and of factors such as BDNF in study models.
Research context
The preclinical literature on Selank has explored its relationship with anxiety, memory and neuroimmune modulation in animal models.
These findings belong to the field of research and do not constitute evidence of efficacy in humans. Selank is offered for research use only.
