Peptide Nasal Sprays

Whether you’re looking to add energy to your workouts, reduce stress and anxiety or boost your immune system, peptide nasal sprays are an easy way to get the job done. These formulas can have a profound effect on the human body and are perfect for athletes, bodybuilders and anyone who wants to improve their health and performance.

Peptides are small proteins that can stimulate specific receptors within cells. Some are able to cross the blood-brain barrier (BBB) and reach the brain, where they can have an impact on a wide range of diseases, including Alzheimer’s disease. A peptide called A1R-CT, which targets the protective adenosine 1 receptor on neurons, has been shown to tamp down uncontrolled electrical activity that is often seen after traumatic brain injury and stroke. It also helps protect neurons in research models of both epilepsy and Alzheimer’s.

Scientists are experimenting with nasal administration of the drug, which they say is safer and more effective than injecting it into the bloodstream. The spray bypasses the BBB and avoids hepatic first-pass metabolism and degradation, which can be problematic for peptide drugs.

Several studies have used the nose-to-brain pathway to deliver peptides to treat CNS disorders. Most use liquid formulations like emulsions and suspensions, but recently a dry powder inhaler (DPI) formulation has been proposed. DPIs are easier to handle than liquids and may offer higher medication stability, lower medication dose, and reduced preservative and propellant content.
