CJC-1295 vs CJC-1295 DAC: What’s the Difference?

The main difference between CJC-1295 and CJC-1295 DAC is mechanism: CJC-1295 is studied for sustained ghrh stimulation research — Short-acting GHRH analog. CJC-1295 DAC is studied for long-acting ghrh analog research — GHRH analog with Drug Affinity Complex (DAC) attached.

Short-acting GHRH analog vs albumin-bound long-acting.
