Peptide Science and Mechanisms

Explore how peptides signal cells, interact with receptors, and are studied across major research areas.

• GLP-1 vs GIP vs Glucagon: What Each Receptor Actually Does

  Semaglutide, Tirzepatide, Retatrutide — they all target hormone receptors. But what do GLP-1, GIP, and glucagon actually do in your body? Here is the plain-language science behind the drugs everyone is talking about.

• How Peptide Drugs Are Actually Made (And Why It Matters to You)

  Peptides are now a $117 billion industry. But how do they actually get made? We break down the science in plain English -- from amino acid building blocks to FDA-level quality testing.

• Peptides vs Steroids: What's the Actual Difference?

  Everyone has heard of steroids. Fewer people understand peptides. And almost nobody explains the difference clearly. Let's fix that.
