CJC1293 w DAC vs CJC1295 w DAC ??

[GoFlyers2017]

I'm well aware of the bleed from CJC1295 w DAC but my mice had no side effects. Does the CJC1293 also come w DAC to give it the longer release also? Why is the 1293 more expensive than the 1295? Other than the GHRP 2 & 6, is there anything else that would work well with either the one of those w DAC to give you a pulse release? I appreciate any input.
