Understanding peptide reconstitution: concentrations, diluents, and stability windows
The chemistry behind reconstitution choices, and what published stability data actually covers.
EducationAlso known as: Modified GRF 1-29 (without DAC), CJC-1295 DAC
CJC-1295 is a modified analog of growth-hormone-releasing hormone. The DAC (Drug Affinity Complex) version binds albumin to extend half-life to roughly a week; the non-DAC version acts briefly. Early human studies demonstrated sustained GH and IGF-1 elevation.
Labeling confusion between DAC and non-DAC versions is common in the research-chemical market, and our testing has repeatedly found products mislabeled between the two forms.
