Description and reported dosing

What is CJC-1295 No DAC?

A modified fragment of growth-hormone-releasing hormone, also sold as Modified GRF (1-29). The “No DAC” part means it lacks the complex that stretches the other version's action across days: this one has a half-life of about 30 minutes.

The short action is the point. It produces a brief pulse of growth hormone release rather than a sustained elevation, which is closer to how the body secretes the hormone on its own. It is most often paired with ipamorelin at the same dose.
