What is peptide therapy? It’s a phrase appearing increasingly often online, particularly around weight management, hormones, recovery, longevity and wellness. But there’s a problem: “Peptide therapy” doesn’t describe one single treatment. The phrase can be used to describe established peptide-based medicines prescribed by healthcare professionals. It can also be used much more loosely by wellness...Read More

Are peptides and SARMs the same thing? No. Peptides and SARMs are fundamentally different types of compounds. They’re often discussed together online, particularly in conversations surrounding fitness, body composition and research compounds. This can make them appear closely related. Scientifically, however, they belong to very different categories. Peptides are chains of amino acids. SARMs are...Read More

Are collagen peptides the same as research peptides? No. They share the word peptide, but they’re very different types of products used in completely different contexts. This can be confusing because someone searching for “peptides” might encounter everything from tubs of collagen powder to highly specific molecules being investigated in laboratory research. Chemically, there is...Read More

Are peptides proteins? They’re closely related — but the terms don’t mean exactly the same thing. Both peptides and proteins are constructed from the same basic building blocks: amino acids. Those amino acids are connected through peptide bonds. The major difference is that proteins are generally larger, more structurally complex molecules, while peptides are usually...Read More

Are peptides safe? It’s one of the most common questions people ask about peptides. But there’s an important problem with the question: There is no single safety profile for “peptides”. Peptides are an enormous family of molecules. Some occur naturally in the human body. Some are ingredients in established medicines. Some have been studied in...Read More

Are peptides legal in the UK? There isn’t a single yes-or-no answer. That’s because “peptide” describes a type of molecule — not a legal category. Peptides occur naturally throughout biology. They can also appear in licensed medicines, cosmetics, laboratory research materials and experimental pharmaceutical research. The legal and regulatory position therefore depends on which peptide...Read More

No. Peptides are not steroids. They are fundamentally different types of molecules. It’s an understandable question, though. Peptides and steroids are frequently discussed in the same online communities, particularly around fitness, metabolism, hormones and performance. That can make them sound like closely related compounds. Chemically, they’re very different. So what actually separates a peptide from...Read More

When reading about peptides, medicines and drug development, you’ll frequently encounter the word: bioavailability. A research paper might report that a compound has: “low oral bioavailability” or researchers may describe a new formulation designed to: “improve bioavailability.” But what does that actually mean? Is 100% bioavailability better? Why can swallowing a peptide produce very different...Read More

If you’ve been reading about peptides or modern metabolic research, you’ve almost certainly encountered terms such as: GLP-1 receptor agonist GIP receptor agonist melanocortin receptor agonist dual agonist or triple agonist. They’re everywhere in peptide research. But what does an agonist actually do? What is a receptor? What’s the difference between an agonist and an...Read More

If you’ve spent any time reading about peptides, GLP-1 compounds or medicines, you’ve probably encountered phrases such as: “This compound has a long half-life.” “Its half-life is approximately five days.” or: “Researchers modified the molecule to extend its half-life.” But what does half-life actually mean? Does a five-day half-life mean a compound completely disappears after...Read More
