CJC-1295 (without DAC) 2 mg – Product Description
Overview:
CJC-1295 without DAC—often referred to as Mod GRF 1-29—is a short-acting synthetic peptide analog of growth hormone–releasing hormone (GHRH). Unlike the DAC version, it is designed for rapid, pulsatile stimulation of natural growth hormone (GH) release. It is commonly supplied as a 2 mg lyophilized (freeze-dried) vial for research use.
Key Features:
- Active Compound: CJC-1295 (without DAC) / Mod GRF 1-29
- Dosage/Form: 2 mg per vial
- Formulation: Lyophilized powder (white/off-white)
- Class: Short-acting GHRH analog
- Half-life: Short (approximately 20–30 minutes)
- Category: Research peptide (not an approved medication)
Mechanism of Action (Research Context):
CJC-1295 (no DAC) works by binding to GHRH receptors in the pituitary gland to:
- Trigger pulsatile release of growth hormone (GH)
- Support natural GH rhythm (more closely mimics physiological secretion)
- Increase IGF-1 levels indirectly through GH stimulation
Because of its short half-life, its effects are brief and more controlled compared to long-acting variants.
Common Research Applications:
- Growth hormone pulsatility studies
- Metabolic and endocrine research
- Muscle recovery and regeneration models
- Fat metabolism investigations
Comparison: With DAC vs Without DAC
- Without DAC (Mod GRF 1-29):
- Rapid onset, short duration
- Mimics natural GH pulses
- Requires frequent administration in research settings
- With DAC:
- Long-acting (lasting several days)
- Sustained GH elevation
- Less frequent dosing
Physical & Handling Information:
- Appearance: White/off-white powder in vial
- Reconstitution: Requires sterile/bacteriostatic water (lab use only)
- Storage:
- Unmixed: Store frozen (−20 °C)
- After mixing: Refrigerate at 2–8 °C
Potential Risks & Side Effects (Non-clinical / Reported):
- Hormonal fluctuations
- Headaches or flushing
- Water retention
- Changes in blood sugar regulation
- Injection site irritation
Warnings:
- Not approved for human or veterinary use
- Intended strictly for laboratory/research purposes
- Limited human safety data available
- Unregulated use may lead to serious health risks
Legal Status:
CJC-1295 (without DAC) is typically sold as a research chemical and is not approved as a pharmaceutical drug in most countries.
Important Note:
This information is for educational purposes only. CJC-1295 (without DAC) is an experimental peptide, and any non-research use carries significant health and legal risks. Always consult a qualified healthcare professional before considering any hormone-related substances.
