Which Peptides Are FDA Approved? Many peptide medicines are approved by the United States Food and Drug Administration. They are used across metabolic health, hormone signalling, digestive health, bone growth, pain, infectious disease and rare conditions. The range is far wider than the handful of peptide names that usually appear online.
The Evidence Behind Peptides Peptides are involved in many parts of biology. They help cells communicate, carry signals and interact with receptors, enzymes and other molecules. Research into peptides ranges from simple laboratory experiments to large human trials. Some peptides have been studied for decades and are used as established medicines.
The different types of peptides and their research profile. Peptides appear throughout biology. Some carry signals between cells, while others bind metals, interact with enzymes, support immune defence, or help move material across cell membranes. A peptide is a chain of amino acids joined by peptide bonds. The National Human Genome
Semax vs Selank Semax and Selank appear quite often together in research which can make them seem like two versions of the same compound. Semax is commonly investigated in research examining neurotrophic signalling, gene expression and responses to neurological stress meaning it may influence the biological processes involved in how
CJC-1295 With DAC vs Without DAC CJC 1295 is often discussed in relation to growth hormone and IGF I signalling. Anyone beginning to research the compound will soon encounter two names, CJC 1295 with DAC and CJC 1295 without DAC. The simplest difference is duration. DAC allows the peptide to remain
Purity vs Identity: Why 99% Purity Does Not Prove a Peptide Is Correctly Labelled A peptide described as 99% pure can sound as though every question about the material has already been answered. The percentage is useful, but it is only one part of the information a laboratory can provide. Think
Peptide Vials vs Pens: What’s the difference? When comparing peptide compounds within research, you may wonder what is the difference between peptide pens and vials, even though they are labelled as containing the same compound, The main difference is how the material is supplied, prepared and measured for research. A vial
Peptide Glossary A to Z of Common Terms Reading about peptides can mean stopping every few lines to look up an unfamiliar word. The research might mention receptors, while a laboratory report lists purity and identity. Understanding these terms makes the information easier to follow. A peptide, a short chain of
How Are Peptides Made? Behind the Manufacturing and Quality Process Peptides may be relatively small compared with proteins, but producing the right peptide consistently involves much more than simply joining amino acids together. A peptide needs to be made to the intended sequence, separated from unwanted material and tested to examine
On 23 and 24 July 2025, the FDA’s Pharmacy Compounding Advisory Committee (PCAC) convened to review seven peptide-related compounds being considered for potential inclusion on the 503A Bulks List. After two days of discussion, six of the seven received positive recommendations from the committee. One did not. For a field that
