Peptide Nasal Sprays

Finished peptide nasal sprays at a fixed concentration — seventeen listings, mostly the nootropic and melanocortin groups, where intranasal delivery is the route the underlying literature uses. Semax, Selank and their amidate variants account for most of the shelf; PT-141 and oxytocin sit alongside them, and BPC-157, glutathione, NAD+ and thymosin alpha-1 are stocked as sprays too, where the spray is itself the delivery question rather than the established route. Ready to use with no reconstitution — but the concentration is set at fill, so a protocol that needs to vary it should order the lyophilized vial instead. The concentrations span more than thirtyfold across an identical pump, from Semax at 0.67–1.33 mg/mL to NAD+ at 20–40 mg/mL, so read the per-actuation figure on each listing rather than assuming the format is uniform.
