CJC-1295
In early studies in healthy adults, growth hormone and IGF-1 rose over several days.
What it does in the body
Findings, each with its evidence level — animal data kept visibly apart from what's unproven in humans.
In early studies in healthy adults, growth hormone and IGF-1 rose over several days.
PROVEN IN HUMANSA chemical tweak (DAC) extends its action from minutes to about 6–8 days.
MECHANISM ONLYThe raised growth hormone is why it is studied for muscle growth and anti-ageing.
MECHANISM ONLYDevelopment stopped after Phase II; long-term safety and benefit for specific indications are not established.
UNPROVEN IN HUMANSMechanism of action
What CJC-1295 does in the body — step by step.
CJC-1295 is a synthetic analog of the body's own growth hormone-releasing hormone (GHRH).
The substance binds selectively to the GHRH receptor in the pituitary, where it stimulates the pulsatile release of growth hormone (GH).
Characteristic of CJC-1295 is the DAC modification (Drug Affinity Complex): a maleimidopropionic acid group binds covalently to circulating serum albumin, thereby extending the half-life from a few minutes to several days.

Frequently asked questions
What is CJC-1295?+
CJC-1295 is a synthetic analog of the body's own growth hormone-releasing hormone (GHRH).
What type of peptide is CJC-1295?+
CJC-1295 belongs to the GHRH analog class.
What is CJC-1295 used for?+
In research, CJC-1295 has primarily been investigated in the context of: Muscle growth, Anti-aging. These are research findings (evidence: early clinical studies), not proven benefits in humans and not a usage recommendation.
Is CJC-1295 legal in Germany?+
CJC-1295 is not approved as a medicine in Germany. Obtaining it outside clinical studies is legally problematic. It is additionally relevant under the German Doping Agent Quantity Ordinance (DmMV).
Is CJC-1295 FDA-approved / legal in the US?+
No. CJC-1295 is not FDA-approved as a drug in the US; it is mostly sold as a research chemical and not for human consumption.
Is CJC-1295 legal in Canada?+
No. CJC-1295 is not authorized by Health Canada and not intended for human consumption.
Where can I buy CJC-1295?+
Peptica sells nothing and names no sources. CJC-1295 is "not approved" in Germany; obtaining unapproved substances outside clinical studies is illegal and carries quality and safety risks.
What is the dosage of CJC-1295?+
Peptica publishes no dosing. There are no approved dosing guidelines for CJC-1295; figures circulating online stem from animal studies or anecdote, not from validated human protocols. This is not medical advice.
Is CJC-1295 banned in sport (WADA)?+
Yes. CJC-1295 is on the WADA Prohibited List and is therefore banned in competitive sport.
What are the known risks of CJC-1295?+
Documented risks include: GH/IGF-1 overstimulation: possible promotion of insulin resistance, acromegaly-like symptoms with overdose; Theoretical cancer risk from elevated IGF-1 levels (promotion of cell growth). This is not a complete safety assessment and not medical advice — see the risks section for the full list.
