The human trial was DAC, not No-DAC
Healthy adults in two short trials of long-acting CJC-1295
What did they want to find out?
Did the long-acting compound raise GH and IGF-I?
What did researchers observe?
It raised both measured hormones and persisted for days.
What does this mean for you?
This is evidence about the DAC-development compound's hormone effects, not this catalog's No-DAC preparation.
What we still do not know
No-DAC fitness benefits or a days-long half-life cannot be inferred from this trial.

Prolonged stimulation of growth hormone (GH) and insulin-like growth factor I secretion by CJC-1295, a long-acting analog of GH-releasing hormone, in healthy adults
Journal of Clinical Endocrinology and Metabolism · 2006
How it was studied
Two randomized double-blind placebo-controlled trials of long-acting CJC-1295 with DAC. Healthy adults aged 21–61; trial durations 28 and 49 days; total count not supplied in the accessed abstract.
Study finding
The long-acting compound raised GH and IGF-I; reported half-life was 5.8–8.1 days.
Study limitations
Related DAC evidence, not direct No-DAC evidence. Hormone increases do not demonstrate improved fitness, sleep or injury recovery; short follow-up cannot establish long-term safety.
