Key Takeaways

  • Measure biomarkers before and after peptide use to adjust dosage based on data, not feelings.
  • Fix sleep, nutrition, and exercise first before turning to peptides as a solution.
  • Avoid open-loop dosing (taking more because you “feel” something) to prevent unsafe escalation.

Notable Quotes

“Without biomarker feedback, dose can escalate based upon your feelings and not data.”

Bottom Line

Use peptides only with biomarker tracking and prioritize foundational health habits first.
