Results vary by protocol, individual health status, dosing, and lifestyle. That said, most patients on GLP-1 protocols (Semaglutide/Tirzepatide) report measurable weight changes within 4–8 weeks. GH secretagogue protocols (Performance Blend, Sermorelin) typically show noticeable changes in sleep quality, recovery, and body composition within 6–12 weeks. Recovery peptides like BPC-157/TB-500 are often felt within 2–4 weeks for acute injuries. NAD+ protocols often report energy and cognitive effects within days of infusion. Your physician will set realistic expectations during your consultation based on your specific goals and health history.
