They're the exact same thing.
It is real CJC 1295 that has the DAC complex and is next to useless because of GH bleed.
Actually they are not the same thing, CJC1293 has the DAC as well. ModGrf(1-29) is CJC1295 with the DAC removed. It is a tetra-substituted peptide chain whereas CJC1293 only has one substitution.
