CJC-1295 with DAC
A clear example of what longer duration costs: the natural pulses disappear.
| Property | Value |
|---|---|
| Type | GHRH analogue with drug affinity complex |
| Receptor | GHRH receptor |
| Duration | Days, flat rather than pulsed |
| Research status | Clinically studied |
| Form | Freeze dried powder |
What it is
The same 29 amino acids as the variant without DAC, with an extra piece attached: the drug affinity complex. That binds chemically to albumin, a protein swimming abundantly in the blood.
How it works
While the peptide is attached to albumin it is too big to be filtered out by the kidneys and enzymes struggle to reach it. Duration goes from minutes to days.
What the research shows
The effect on growth hormone levels in blood is well described. At the same time this substance shows why longer is not always better: the growth hormone axis works naturally in pulses, and flat stimulation changes the system you set out to study.
Research status
Clinically studied in humans.
Practical
When ordering, check carefully which of the two variants you have; both are called CJC-1295.
