In Plain English
Selank with a protective cap on one end to make it last longer in your body. Selank is already mild and calming; the acetylated version does the same thing but requires less and works for longer. Like a slow-release version of the same compound.
Overview
N-Acetyl Selank is the N-terminally acetylated form of Selank, a synthetic analogue of tuftsin developed in Russia. The acetylation reduces enzymatic degradation at the N-terminus, potentially increasing potency and extending the duration of action. Like Selank, it is primarily studied for anxiolytic and cognitive-enhancing properties. Users describe it as smoother and more potent than regular Selank, though comparative human data is essentially absent.
Common Formats
- Intranasal solution (research)
- Lyophilized powder
Storage Notes
Store lyophilized at -20°C. Reconstituted intranasal solution: refrigerate, use within weeks.
