Sublingual spray instead of a capsule.

Unlike conventional capsule-based peptide supplements, Epitalon Spray is formulated as a sublingual oral spray, allowing the active ingredients to be absorbed directly through the oral mucosa rather than the digestive tract. The patented tetrapeptide complex — alanine, glutamic acid, aspartic acid and glycine — is the result of decades of research by Professor V.H. Khavinson and the International Research Foundation for Peptide Bioregulation.
