Peptide dosing can be confusing because the term peptide covers everything from fully FDA-approved prescription medications to experimental research compounds that have never completed a human dose-finding study. For that reason, this guide uses three different classifications: FDA-approved dosing means the schedule comes from current pharmaceutical prescribing information. Clinical/research peptide dosages means the amount has […]

When working with lyophilized peptides in a laboratory setting, researchers frequently encounter another product alongside the peptide vial: bacteriostatic water. Bac water is a sterile preparation of water containing a small amount of antimicrobial preservative. In the United States, commercially manufactured Bacteriostatic Water for Injection typically contains 0.9% benzyl alcohol as the bacteriostatic preservative. DailyMed […]

One of the primary reasons peptides are commonly supplied in lyophilized, or freeze-dried, form is stability. Removing most of the water from a peptide formulation can dramatically slow many of the chemical reactions that contribute to degradation. But lyophilization does not make a peptide indestructible. Temperature, moisture, oxygen, light, packaging, repeated temperature changes, and the […]

When purchasing or evaluating research peptides, you will frequently encounter the term COA, or Certificate of Analysis. It is one of the most important documents associated with a peptide—but it is also one of the most commonly misunderstood. A Certificate of Analysis is essentially a laboratory report describing a particular sample or batch and the […]

Peptides are short chains of amino acids that participate in an enormous range of biological processes. As peptide science has advanced, researchers and pharmaceutical developers have faced an important question: What is the best way to deliver a peptide to its intended destination? Unlike many conventional small-molecule compounds, peptides can be relatively large, water-soluble molecules […]

Peptides have become an increasingly important area of scientific research, appearing in studies involving metabolism, cellular signaling, tissue repair, immune function, aging, neurological processes, and many other biological systems. However, peptides present researchers and manufacturers with an important challenge: stability. Many peptides are relatively delicate molecules. When maintained in a liquid solution for extended periods, […]
