Nasal delivery

Nasal sprays, ready to use.

Nasal delivery skips reconstitution completely. These arrive pre-mixed in 10ml bottles at a stated concentration, which removes the single biggest source of error in peptide research — the mixing step. The nootropic peptides in particular (Semax, Selank) have a long history of intranasal use in the Russian clinical literature, which is where most of the published work on them lives.

How we review suppliers

CD Biolab is an independent research library. We do not manufacture, stock, price, test or ship anything. We review suppliers on their published testing standards, reputation, fulfilment record and pricing, and the ratings we publish are our own editorial assessment. Product photography on this site is © ZestyRat Research and is shown to identify the products they sell — not to represent stock held by CD Biolab.

Every compound referenced on this site is sold by its vendor strictly as a research chemical for in-vitro laboratory research only — not for human or animal consumption, and not intended to diagnose, treat, cure or prevent any disease. Nothing here is medical advice. We earn a commission on orders placed through our links, at no additional cost to you; all material connections are disclosed in line with FTC guidelines.
