DAC vs Non-DAC Peptides Explained (2026)

What DAC Actually Stands For DAC stands for Drug Affinity Complex, a chemical modification attached to certain GHRH analog peptides, most notably CJC-1295, that fundamentally changes how long the compound remains active in the bloodstream. This is not a vague structural tweak, it is a specific, well characterized chemical mechanism, and understanding what it actually […]
Peptide Labeling Explained (2026)

Why the Label Matters as Much as the COA Most quality discussions in research peptides focus entirely on the Certificate of Analysis, and rightly so, since the COA is the authoritative testing document. But the vial label is what actually arrives in your hands, and it serves a different purpose than the COA does. The […]
Understanding Peptide Concentrations and Measurements

Why Concentration Math Trips People Up A vial labeled 5mg and a vial labeled 10mg are not automatically twice as different in actual usable concentration once reconstituted, and this confusion is one of the most common sources of error in research peptide handling. The labeled mass on a vial tells you the total amount of […]
Common Research Peptide Terms Explained (2026)

Why This Glossary Exists Anyone reading peptide product pages, COAs, or research literature for the first time runs into the same handful of terms repeatedly, lyophilized, reconstitution, half-life, batch number, and several others that get used without ever being explained. This glossary covers the terms that come up most often across research peptide documentation, organized […]
Types of Research Peptides — A Complete Category Overview (2026)

Why Categorizing Peptides Matters There are now hundreds of peptide compounds under active research, and trying to understand them one at a time without any organizing framework makes the field feel far more fragmented than it actually is. Once you group peptides by the biological system they primarily act on, the landscape becomes much easier […]
