Research Peptide Nasal Sprays
This collection covers our ready-to-use research nasal sprays: single-peptide sprays of Selank, Semax, VIP and Ara-290, a coenzyme spray of NAD+, and two neuropeptide combinations, plus four shelf-stable PRO sprays: NAD+ PRO, Selank / Semax PRO, PT-141 / Oxytocin PRO and Ipamorelin / CJC-1295. Each spray comes in a metered spray bottle, with the amount of compound and the fill volume printed on the label and listed on the product page.
What Is a Peptide Nasal Spray?
A peptide nasal spray is a research compound that arrives already dissolved in an aqueous solution, in a metered spray bottle. Because the solution is prepared in advance, researchers can work with it straight away, without the reconstitution step a lyophilized vial requires. All sprays are sold strictly for laboratory research and are not for human or veterinary use.
Our Research Nasal Sprays
- Selank Nasal Spray (30 mg in 10 mL): Selank is a synthetic peptide derived from tuftsin, studied for cognitive function, anxiety modulation and serotonin and dopamine balance.
- Semax Nasal Spray (30 mg in 10 mL): Semax is derived from ACTH fragments and is studied for cognitive function, neuroprotection and its influence on brain-derived neurotrophic factor (BDNF).
- Selank / Semax Nasal Spray (10/10 mg in 10 mL): both neuropeptides in one spray, for studies of neuropeptide signaling and peptide-receptor interactions.
- Selank / Semax / Pinealon Nasal Spray (20/20/20 mg in 10 mL): three research peptides combined in one prepared material, so they can be studied together.
- VIP Nasal Spray (20 mg in 15 mL): vasoactive intestinal peptide, for research on VIP-related peptide signaling.
- Ara-290 Nasal Spray (10 mg in 15 mL): the research peptide Ara-290 in a ready-to-use format.
- NAD+ Nasal Spray (4,500 mg in 15 mL): the coenzyme NAD+, studied for mitochondrial function, ATP production and DNA repair through sirtuins and PARPs.
- NAD+ PRO Nasal Spray (500 mg in 10 mL): NAD+ in the shelf-stable PRO formulation, with a 12-month shelf life and no refrigeration required.
- Selank / Semax PRO Nasal Spray (10/10 mg or 20/20 mg in 10 mL): both neuropeptides in the shelf-stable PRO formulation.
- PT-141 / Oxytocin PRO Nasal Spray (20/10 mg in 10 mL): PT-141, studied at melanocortin receptors, combined with oxytocin, studied for social bonding and stress response.
- Ipamorelin / CJC-1295 Nasal Spray (10/5 mg in 10 mL): two peptides studied for growth hormone release, labeled PRO.
What Does PRO Mean?
PRO sprays are the shelf-stable formulation: they have a 12-month shelf life and need no refrigeration. The other sprays in this collection are refrigerated at 2–8 °C after receipt.
Nasal Sprays vs. Lyophilized Vials
Lyophilized vials are the most stable format for long-term storage and let researchers prepare their own concentrations. Nasal sprays trade that flexibility for convenience: the concentration is set, the solution is ready to use and every spray comes from the same prepared batch. Selank, Semax, the Selank / Semax combination and NAD+ are available in both formats, so studies can compare them directly.
Why Researchers Use Ready-to-Use Sprays
- No reconstitution step, so less preparation time and handling
- A fixed, labeled concentration in every bottle
- A metered spray bottle for consistent, repeatable measured amounts
- Combination sprays that keep the ratio between peptides identical from bottle to bottle
Choosing a Nasal Spray by Research Area
- Cognitive function and neuroprotection: Semax, or Selank / Semax for both neuropeptides together
- Anxiety modulation and neurotransmitter balance: Selank
- Multi-peptide neuropeptide studies: Selank / Semax / Pinealon
- Cellular energy and DNA repair: NAD+
- VIP-related peptide signaling: VIP
- Growth hormone release: Ipamorelin / CJC-1295
- Melanocortin signaling and social behavior: PT-141 / Oxytocin PRO
How to Store Peptide Nasal Sprays
Refrigerate standard nasal sprays at 2–8 °C after receipt and keep them capped between uses; PRO sprays need no refrigeration and have a 12-month shelf life. Unlike lyophilized vials, sprays are already in solution, so cold storage matters more for keeping the material stable over the course of a study. The exact storage conditions for each spray are listed on its product page.
Testing and Lot Documentation
Each spray's product page shows the status of the current lot's certificate of analysis. Until a lot's certificate is published, the page reads "Lot COA coming soon"; published certificates are added to our COA library, searchable by compound or lot number.
