Growth hormone peptides are some of the most talked-about compounds in longevity medicine, metabolic health, and hormone optimization. But how do they actually work inside the body?

In this episode of Peptides Explained, we break down the science behind four growth hormone secretagogues: Sermorelin, Tesamorelin, CJC-1295, and Ipamorelin.

Instead of injecting growth hormone directly, these peptides stimulate the pituitary gland to release the body’s own growth hormone through different biological pathways.

We explore the physiology of the growth hormone axis, the role of GHRH, IGF-1, and ghrelin signaling, and how these peptides may influence metabolism, recovery, and sleep.

You’ll also learn the differences between these compounds, why CJC-1295 and Ipamorelin are often stacked, and what the clinical research actually shows.

Topics covered in this episode include:

• How growth hormone is regulated in the body
• The biological role of ghrelin and GH pulses during sleep
• The difference between Sermorelin, Tesamorelin, CJC-1295, and Ipamorelin
• What DAC (Drug Affinity Complex) means in CJC-1295
• Potential effects on IGF-1, metabolism, and recovery
• Possible side effects, including effects on prolactin and glucose metabolism
• What the clinical evidence actually supports

As always, this podcast focuses on biological mechanisms and scientific evidence so you can understand how peptide therapies interact with human physiology.
