CJC-1295
Reviewed on
Approval and product status
Still being studied. This review found no FDA-approved CJC-1295 product in the United States.
Some products use the name CJC-1295 for different chemical forms, including different salts. Some have a chemical part called DAC, and some do not. FDA says evidence for the DAC form cannot prove the same effects for a no-DAC form. These products are not automatically the same as modified GRF 1-29 or pharmacy-made mixtures with other ingredients.
What was measured in people?
- Health results · Limited
- Studies in people measured hormone levels. They did not test lasting health benefits.
- Body changes · Moderate
- Short studies in healthy adults found that CJC-1295 raised growth hormone and insulin-like growth factor 1 (IGF-1) for a time.
A change in a hormone or body signal does not by itself prove a health benefit.
Important limits
This tool is not an independent medical review. It does not recommend treatment.
FDA says compounded CJC-1295 may pose a risk of unwanted immune reactions when given by certain routes. FDA also describes possible quality concerns, including peptide impurities and incomplete information about the active ingredient. FDA reports serious events associated with CJC-1295, including a faster heart rate and a whole-body reaction in which blood vessels widen. The small published studies did not report those serious events. Available clinical data are limited. This guide gives no dose or personal-use instructions.
Still unknown: Higher hormone levels do not prove less body fat, more muscle, better recovery, better sleep, more energy, or a longer life. These studies did not establish those popular claims. Long-term safety is still unclear.

What the research shows
Two studies assigned healthy adults to groups by chance. Some received CJC-1295, and some received a placebo, an inactive comparison. The studies found that growth hormone and IGF-1 stayed higher for a time. Another study found changes in how growth hormone was released. These studies measured body signals, not health benefits.
