CJC-1295 w/ DAC Peptide Therapy
CJC-1295 with DAC is a synthetic peptide designed to stimulate growth hormone (GH) release from the pituitary gland. It is a modified version of Growth Hormone Releasing Hormone (GHRH), enhanced with Drug Affinity Complex (DAC) technology to dramatically extend its half-life and activity in the body. This makes it a popular option for those exploring peptide therapy for muscle growth, fat loss, anti-ageing and recovery. At The Catalyst Clinic, we provide expert consultation and personalised peptide therapy, including CJC-1295 with DAC.
What is CJC-1295 w/ DAC?
CJC-1295 is a GHRH analogue that mimics the action of the natural hormone.
Stimulates GH release – binds to pituitary receptors and promotes natural growth hormone secretion.
Extended duration – the DAC modification binds the peptide to albumin in the blood, protecting it from breakdown.
Less frequent dosing – with a half-life of around 6–8 days, it requires far fewer injections than other GHRH peptides.
In simple terms: CJC-1295 with DAC helps the body release more of its own growth hormone, but in a longer-lasting, more convenient way.
Benefits of CJC-1295 w/ DAC
- • Increased growth hormone levels – supporting lean muscle growth and recovery
- • Fat reduction – improved fat metabolism and body composition
- • Better sleep quality – GH plays a role in deep, restorative sleep cycles
- • Anti-ageing support – improved skin elasticity, collagen production and vitality
- • Immune support – GH is involved in cellular repair and immune function
- • Convenient dosing – extended half-life allows for weekly or less frequent administration
How CJC-1295 Works
- • Acts as a GHRH analogue, binding to pituitary receptors to trigger GH release
- • DAC technology extends its activity, maintaining stable GH elevation for days rather than hours
- • Increases IGF-1 levels (through GH release), supporting tissue growth, fat metabolism, and repair
Potential Therapeutic Applications
- • Growth hormone deficiency
- • Muscle wasting conditions
- • Age-related decline in GH
- • Metabolic health and fat loss
- • General regenerative and anti-ageing support
Note: CJC-1295 is investigational and not currently licensed as a medical therapy. Clinical supervision is essential.
Safety, Side Effects & Administration
CJC-1295 is generally well tolerated, but possible side effects include:
- • Water retention
- • Joint pain or stiffness
- • Carpal tunnel-like symptoms
- • Increased appetite
Long-term effects are still under study. At The Catalyst Clinic, peptide therapy is only offered after full consultation and ongoing medical monitoring.
Administration: Typically delivered via subcutaneous injection. Cyclcing of this is essential.

FAQs
-
It is mainly studied for growth hormone support, muscle recovery, fat loss, and anti-ageing applications.
-
CJC-1295 with DAC has a much longer half-life, requiring weekly injections, while CJC-1295 without DAC is short-acting and typically needs daily injections. The addition of DAC prolongs the peptide’s activity in the body by enhancing its binding to albumin.
-
Generally well tolerated, though side effects like water retention and joint discomfort can occur. Long-term safety is still under research.
-
Yes. The Catalyst Clinic offers consultations and supervised peptide therapy including CJC-1295 with DAC at our London clinic.
