This Is Why Your Peptides Aren’t Working

About this video

Yurth explains why, in her practice, peptides often appear not to work: she argues they are signals, not overrides, and a body lacking energy, building blocks or a sense of safety cannot respond to a signal. She outlines three prerequisites she checks first — mitochondrial energy capacity supported by basic nutrients, adequate substrate for hormones and tissues including healthy fats and minerals, and a nervous system not locked in chronic stress or threat. She also warns that unresolved inflammation, viral or gut-immune issues can make signalling counterproductive. Her hierarchy is to optimise hormones, nutrition and stress first, then introduce repair peptides.

Key takeaways

• Treat peptides as signals that need a ready system, not as forces that compel results
• Check energy availability and mitochondrial basics before escalating, Yurth advises
• Ensure nutritional building blocks for hormone synthesis are present
• Address chronic stress and threat perception as part of any protocol
