Do a few studies prove a therapy?

No. A change in a blood test in healthy volunteers is not the same as proof that a treatment helps patients.

Short answer

In its 2024 review, the FDA counted 63 healthy adults across the published human studies, and about three in four of them got only one shot.

Those studies were published from 2006 through 2009 and did not enroll people being treated for a disease or condition.

What the studies did find

The first study found that one shot of the DAC form raised growth hormone, and IGF-1 (a related growth signal in the blood), for days afterwards.

A study of 12 young men found that growth hormone still rose and fell in pulses after the compound was given.

Those are hormone measurements. They are not patient outcomes.

The gap the headline can hide

No human study has shown that CJC-1295 treats any condition.

Keep this line

Ask what changed for people, not only what changed in a blood measurement.
