Intranasal Spray Dosing Guide
This Intranasal Spray Dosing Guide provides suggested research-based protocols for
PureLife Peptides' intranasal sprays. These guidelines are based on Dr. Seeds’ peptide
research protocols and other leading industry standards. The information below is designed
to provide clarity on recommended starting dosages, frequency of use, and optimal timing
for administration to help researchers maintain consistency in their studies.
Dosages may be adjusted based on individual research needs and response to
administration. Suggested protocols below serve as a baseline, but researchers may
gradually increase dosages as required to optimize study outcomes while maintaining
appropriate safety considerations.

General Administration Guidelines
• Suggested Dosages: The doses provided below are based on established research
protocols. Dosing can be adjusted based on experimental needs.
• Administration: Administer one spray per nostril per administration to ensure even
distribution and optimal absorption.
• Storage: Keep refrigerated once opened. Store in a cool, dry place away from direct sunlight.
• Timing Consistency: For best results, administer peptides at the same time each day to
maintain consistency in research applications.
• Adaptability: Dosages may be increased gradually if necessary, depending on individual
study parameters, peptide half-life, and observed response.
