02How They Differ
Selank
A synthetic tuftsin analog studied for GABAergic modulation and anxiolytic signaling.
Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin. Research focuses on its modulation of GABAergic neurotransmission and influence on BDNF expression, studied in anxiety and stress behavioral models.
DSIP
A nonapeptide studied for delta-wave sleep architecture and circadian signaling.
DSIP (delta sleep-inducing peptide) is a naturally occurring nonapeptide first isolated for its association with delta-wave EEG activity. Research models study its role in sleep architecture and circadian regulation.

03Selecting for a Research Model
Because Selank and DSIP are both cognitive research compounds, they are frequently evaluated against one another. Selection depends entirely on the research question, model system, and endpoints being measured. Both compounds are supplied strictly for in-vitro and laboratory research and are not for human or veterinary use.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
