GLP-1 has become one of the most recognised hormone pathways in modern metabolic research. But another peptide hormone is attracting increasing scientific attention: amylin. The two are sometimes discussed together because both participate in metabolic regulation, but amylin and GLP-1 are not the same hormone and don’t act through the same receptor system. Understanding the...Read More

The next generation of metabolic research is expanding well beyond conventional GLP-1 receptor agonists. One of the most interesting emerging compounds is zenagamtide, previously known during development as amycretin. Unlike approaches focused exclusively on GLP-1, zenagamtide is designed to combine GLP-1 receptor agonism with amylin receptor agonism in a single molecule. That makes it an...Read More

CagriSema and retatrutide are two of the most closely followed programmes in current metabolic research. They’re frequently discussed together because both represent attempts to move beyond conventional single-pathway GLP-1 research. Scientifically, however, CagriSema and retatrutide take very different approaches. One combines two compounds targeting different signalling systems. The other is a single molecule designed to...Read More

For several years, GLP-1 receptor agonists have dominated discussion around metabolic research. But another hormone pathway is receiving increasing scientific attention: amylin. One of the most prominent compounds in this field is cagrilintide. Cagrilintide is being investigated both independently and in combination with semaglutide, where the combination is known as CagriSema. So what is cagrilintide,...Read More

Retatrutide has become one of the most closely watched investigational compounds in metabolic research. Interest has increased significantly during 2026 as results from multiple Phase 3 clinical trials have become available. The research programme is also considerably broader than weight management alone, examining areas including type 2 diabetes, obstructive sleep apnoea, knee osteoarthritis and other...Read More

Your body uses peptide signals constantly. A peptide appears. It interacts with its biological target. A message is transmitted. Then what? Does the peptide: stay there forever? Does the body recycle it? Does it simply disappear? This leads to one of the most interesting parts of peptide biology: THE BODY HAS TO TURN SIGNALS OFF....Read More

Peptides are constantly described using phrases such as: “cell signalling” “receptor activation” and: “biological communication.” But what does any of that actually mean? How can a tiny chain of amino acids: tell a cell to do something? The answer lies in one of the most important concepts in biology: RECEPTORS. Your cells aren’t simply passive...Read More

Are peptides hormones? It sounds like a simple question. The answer is: SOME ARE. But many aren’t. And some hormones aren’t peptides at all. That’s where the confusion starts. Terms such as: peptide hormone protein neuropeptide and: signalling molecule are constantly used together. Online, they’re sometimes treated as though they’re different names for the same...Read More

A new peptide study appears. Within days, social media is asking: “WHEN WILL THIS BE AVAILABLE?” A compound produces an interesting laboratory result. Suddenly: “THIS COULD CHANGE EVERYTHING.” An early clinical study looks promising. And the internet behaves as though the scientific process is practically finished. It isn’t. One of the least understood things about...Read More

Pick up a premium skincare product today and there’s a good chance you’ll see one word somewhere on the packaging: PEPTIDES. Peptide serum. Copper peptides. Multi-peptide complex. Collagen peptides. Signal peptides. Peptide moisturiser. Some products contain one. Others proudly advertise: 5 PEPTIDES. 10 PEPTIDES. Or an impressive-sounding: PEPTIDE COMPLEX. So what happened? Why has a...Read More
