Selank + Semax
The two regulatory peptides appear side by side throughout the literature — one derived from tuftsin, the other from ACTH (4-10) — and are frequently studied together in cognitive-performance and stress-response models.

Cognitive.
Selank, Semax and DSIP — as lyophilised vials and pre-mixed nasal sprays.
Three short peptides with three different jobs in the literature: Selank in anxiety-model and neuroimmune work, Semax in BDNF-expression and neuroprotection studies, DSIP in sleep-architecture and circadian research. Each is stocked as a lyophilised vial and as a pre-mixed intranasal formulation, with the bacteriostatic water to reconstitute the vials.

Studied together
The pairings the literature keeps coming back to.
Which compounds appear together in the published work on this shelf, and which of those we supply pre-blended at a printed ratio. Descriptions of the literature, not instructions — every product is supplied for laboratory research use only.
DSIP on its own
Delta sleep-inducing peptide is usually studied alone, in sleep-architecture and circadian models, which makes it the simplest listing on this shelf: one vial, one diluent.
- DSIP10mg
- Bacteriostatic Water10 mL
The intranasal arm
All three compounds have an intranasal literature of their own. The sprays are the same peptides pre-mixed in solution, so there is no reconstitution step.
