Choose Injectable Delivery When: Maximum bioavailability and systemic distribution are required Your peptide has a molecular weight exceeding 6,000 Da Precise dosing and reproducible pharmacokinetics are necessary Youre using peptides for bodybuilding or muscle growth The peptide lacks CNS targets Choose Nasal Delivery When: Direct CNS delivery and blood-brain barrier bypass are therapeutic objectives Your peptide is small (under 6,000 Da) and shows adequate nasal bioavailability Rapid onset of action (minutes) is clinically valuable Patient compliance and comfort are primary concerns Youre using neurological peptides like Semax or Selank The FDA has approved several intranasal peptide formulations, including ZAVZPRET for acute migraine treatment, validating this delivery route as pharmaceutically viable
