nasal sprays typically achieve less than 5% Molecular weight determines success for instance, peptides under 6,000 Da work best nasally Nasal delivery bypasses the blood-brain barrier for direct CNS access The peptide you choose matters more than the delivery method itself Injectable vs Nasal: Understanding the Core Differences Before we dive deep, here are the key differences to know about both peptide delivery methods: Injectable Peptides: Have superior bioavailability (nearly 100% systemic absorption) Provide precise dosing and predictable results Work for virtually any peptide regardless of molecular weight Require proper reconstitution and injection technique Nasal Spray Peptides: Typically achieve less than 5% bioavailability for most peptides Bypass the blood-brain barrier for direct CNS delivery Work best for peptides under a molecular weight of 6,000 Da Offer convenience and eliminate needle anxiety As youll see later in this article, the right question to ask isnt about whether nasal sprays or injections are better
