What differs between CJC-1295 no DAC and CJC-1295 with DAC
The same modified GRF (1-29) backbone; the DAC line adds a thirtieth residue carrying a maleimidopropionic acid group, about 280 mass units more. That group is reactive, and it brings the DAC line’s calculated mass to 3,647.3. The DAC-free line has no such constraint and is the simpler vial to hold in stock. The line listed as CJC-1295 carries the With DAC line's CAS number and mass, so read it with the DAC side of this table.

Questions
What is the difference between CJC-1295 no DAC and CJC-1295 with DAC?
The same modified GRF (1-29) backbone; the DAC line adds a thirtieth residue carrying a maleimidopropionic acid group, about 280 mass units more. That group is reactive, and it brings the DAC line’s calculated mass to 3,647.3.
What does the DAC residue add, atom by atom?
C13H17N3O4, the whole 279.3 by which 3,647.3 exceeds 3,368.0 (C165H269N47O46 against C152H252N44O42): a lysine at position 30 and the maleimidopropionyl group on its side chain. The 29 residues before it are the same, with the four changes that turn sermorelin into modified GRF (1-29), so both lines have three glutamines and five basic residues, and at four charges the DAC line is at m/z 912.8 and the other at 843.0.
Which is cheaper per mg, CJC-1295 no DAC or CJC-1295 with DAC?
At 5mg, the only strength both are offered in, CJC-1295 with DAC is the cheaper per mg: $1.683 per mg against $1.890 (CD5 in 50-box lots, CND5).
What are the molecular weights of CJC-1295 no DAC and CJC-1295 with DAC?
CJC-1295 no DAC’s calculated average mass is 3,368.0 g/mol and CJC-1295 with DAC’s 3,647.3 g/mol, 279.3 apart; in electrospray the ions come at m/z 1123.7 and 843.0 (3+ and 4+) for CJC-1295 no DAC against 1216.8 and 912.8 (3+ and 4+) for CJC-1295 with DAC. On each certificate the measured mass is matched to the line’s calculated average mass, within about one unit, as how to read a peptide COA sets out.
Are CJC-1295 no DAC and CJC-1295 with DAC made to the same specification?
Yes: both are supplied to purity not less than 98.0 percent by RP-HPLC and net content within 5 percent of label, and each certificate reports those with a measured mass, matched to the calculated figure on each sheet. The retest date is on the batch record. What differs is each molecule’s own chemistry, described on its compound page.
