Evidence brief
CJC-1295
Written and source-checked by Anthony Treviso, founder of The Peptide Field.
Direct answer
Still being studied. This review found no FDA-approved CJC-1295 product in the United States.
Short studies in healthy adults found that CJC-1295 raised growth hormone (GH) and insulin-like growth factor 1 (IGF-1). These hormone measurements do not prove better recovery, muscle gain, or fat loss.
- How strong is the evidence?
- Emerging
Some studies in people exist. Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation. - What evidence exists?
- Human pharmacology only
Studies in people measured how the substance changed the body. This did not establish a health benefit on its own. - Sports rules
- Prohibited
The checked rules list this substance or group as prohibited under the stated conditions. Check the current rules for your sport.

01 · Evidence profile
Four questions about the evidence
Studies in people measured hormone levels. They did not test lasting health benefits.
Short studies in healthy adults found that CJC-1295 raised growth hormone and insulin-like growth factor 1 (IGF-1) for a time.
The studies were short. FDA reports serious unwanted events, limited clinical data, and concerns about unwanted material in peptide products.
Online pages may use the name CJC-1295 for versions with DAC, without DAC, different salt forms, or mixtures with other ingredients.
02 · Identity
What it is
Growth hormone-releasing hormone is a body signal. It tells the body to release growth hormone. CJC-1295 is a changed version made to last longer. Online pages may use the name CJC-1295 for different forms. Some have a chemical part called DAC, and some do not.
Scientific group: Long-acting version of a body signal that tells the body to release growth hormone. This group name describes the type of molecule or body signal. It does not prove a benefit, safety, or approval.
03 · Exact product
The molecule is not the finished product.
Formulation: The finished product's ingredients and physical form. Route: How the product enters the body. Indication: The approved or studied use and group of people for a product.
None identified in the United States.
- No FDA-approved indication
04 · Research results
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.
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.
Exact product
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.
05 · Claim check
Claims I checked
3 claims checked for this brief.
“CJC-1295 can raise GH and IGF-1 in healthy adults.”
Studies in people found that both hormones stayed higher for a time. This is a change in body measurements, not proof of a health benefit.
- Evidence used
- Human pharmacology. This answer uses a study of how the substance enters or changes the body in people. This alone does not show a health benefit.
- Limits of this answer
- Short-term changes in GH and IGF-1 measured in the healthy adults studied. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“CJC-1295 builds muscle and burns fat in people.”
The cited studies did not test lasting changes in body fat, muscle, or what people could do physically.
- Evidence used
- No reliable human outcome evidence. No reliable study in people shows the health outcome in this statement.
- Limits of this answer
- Lasting changes in body fat, muscle, or what people could do physically. The cited hormone studies did not test these outcomes. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.
“All products called CJC-1295 are interchangeable.”
Research papers and sellers may use the name for different forms, including different salts, changed versions, or mixtures with other ingredients.
- Evidence used
- Regulatory or product record. This answer uses an official regulator record or a specific product label.
- Limits of this answer
- Products labeled CJC-1295 that differ in form, salt, chemical changes, added ingredients, or quality controls. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.

Still being studied. This review found no FDA-approved CJC-1295 product in the United States.
Prohibited. The 2026 WADA list names CJC-1295 as a growth hormone-releasing hormone analogue. It is prohibited at all times for athletes covered by the list. This status is not personal clearance to compete.

07 · Safety
Safety limits for this record
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.
