Semaglutide vs Tirzepatide: A Research Comparison
Semaglutide and tirzepatide are often lumped together, but as research tools they answer different questions. One isolates the GLP…
The FDA Peptide Vote: Staff Said No, the Panel Said Yes
An FDA advisory committee just voted to recommend two research peptides for the compounding list — against its own staff's advice.…
How Cerberus Documents Its Lots: Our Peptide COA Practices, Explained
Every supplier in this market says its material is tested. The useful question is narrower: what exactly do they publish, who prod…
Reconstitution, Done Right: A Lab-Handling Walkthrough
A lyophilized peptide is stable, forgiving, and easy to ship. The moment solvent hits the cake, all three stop being true. Here is…
Peptide Research News Roundup: October 2026
Five peer-reviewed papers from August and September 2026, read for what they actually tested: a five-receptor combination in obese…
Peptide Stability and the Cold Chain: A Lab-Handling Overview
A peptide that is stable for a year lyophilized in a freezer can lose meaningful integrity within days once reconstituted and left…
How to Read a Peptide Certificate of Analysis (COA)
A Certificate of Analysis is the single most useful document a peptide supplier can hand you — and the easiest one to fake convinc…
How Much Solvent? The Reconstitution Volume Trade-Off
Vial mass is printed on the label. Solvent volume is the only number you choose — and it quietly decides how precisely anything ca…
What a “Unit” Actually Measures on a U-100 Barrel
“Ten units” is one of the most-repeated figures in this space and one of the least meaningful on its own. A unit is a mark on a ba…
Epitalon and the Longevity Peptides: What the Research Actually Studies
Epitalon is a four-amino-acid peptide with an outsized reputation. Understanding where it came from — a Soviet-era program that gr…
GHK-Cu: What the Copper-Peptide Research Actually Studies
They call it the "Pretty Boy Peptide," but the nickname is about fifty years younger than the molecule. GHK was isolated…
The Melanocortin System: What MT-2 and PT-141 Research Actually Studies
MT-2 and PT-141 are often discussed as if they were products with effects. In the research literature they are something more usef…
NAD+ and Cellular-Energy Research: What the Science Actually Studies
NAD+ sits at the center of two very different jobs in the cell: it is the electron carrier that makes energy metabolism possible, …
How Snake Venom Became a Blood-Pressure Drug
One of the most-prescribed blood-pressure drug classes in the world started as a way for a pit viper to drop its prey's blood pres…

TB-500 and thymosin beta-4 are used as synonyms almost everywhere online, and that is the single most consequential error in this …
Tesamorelin and the GH Axis: What the Research Literature Studies
Tesamorelin is a useful case study in peptide engineering: a single N-terminal modification to a native hypothalamic hormone chang…
Cagrilintide and the Amylin Comeback
Amylin spent years as the quieter partner to insulin in metabolic research. Cagrilintide, a long-acting amylin-receptor agonist, i…
BPC-157: What the Tissue-Repair Research Actually Studies
Few research peptides carry as much online mythology as BPC-157. Strip that away and what remains is a body of preclinical work on…
GLP-1 Peptides in 2026: The Research Landscape
GLP-1 research has moved fast: a single-pathway hormone tool became a dual agonist, then a triple agonist, in a few short years. H…
Retatrutide and the Triple-Agonist Era
The metabolic research field moved from single GLP-1 signaling to dual agonists to triple agonists in just a few years. Retatrutid…
