CJC-1295 is available in two distinct reference-material forms. They share a core sequence but differ structurally, which changes their molecular weight and identifiers.
No-DAC (Mod GRF 1-29)
CJC-1295 “without DAC”, also called Modified GRF (1-29), is a 29-residue growth-hormone-releasing-hormone analogue, often listed simply as “Mod GRF 1-29”.
With DAC
The “DAC” form carries a Drug Affinity Complex modification, giving a higher molecular weight and a different CAS number.
Matching the reference standard
For assay design the No-DAC and DAC forms are not interchangeable: their masses and identifiers differ, so the COA must match the intended molecule. VERIPHASE supplies CJC-1295 No-DAC (Mod GRF 1-29) as an in-vitro reference standard.
