Intranasal Peptide Sprays Canada — Metered Research Sprays

Sprays carry a peptide already in solution, in a metered pump that delivers a fixed quantity per actuation — the figure on the label reads as micrograms per spray rather than milligrams per vial. The compounds supplied this way are the ones whose intranasal route has its own research literature: the Russian nootropic peptides semax and selank (and their N-acetyl amidate forms) were developed and characterised as intranasal preparations from the outset, and oxytocin, PT-141 and kisspeptin-10 are studied intranasally for the same reason — the route is part of the research question, not an afterthought.

A spray is prepared from the same powder batch as the vial of the same compound, so its certificate is the lot certificate for that powder; the spray page says which batch it was filled from and links the certificate. What a spray adds is a solution, and that is the figure to read: the total milligrams in the bottle divided across the number of metered actuations.

Solution stability is shorter than powder stability, and the product pages state the storage condition the compound needs. Supplied strictly for laboratory research use, shipped within Canada.
