What is CJC-1295?
CJC-1295 is a synthetic analogue of Growth Hormone-Releasing Hormone (GHRH). Its purpose is to stimulate the pituitary gland to release more of the body's own growth hormone (GH). It comes in two primary forms: CJC-1295 without DAC (a modified version of GHRH with a short half-life of around 30 minutes) and CJC-1295 with DAC (which has a "Drug Affinity Complex" added, extending its half-life to about 8 days by binding to albumin in the blood).
What It's Used For
CJC-1295 is researched for its potential to increase growth hormone levels, which is associated with several outcomes. Common research areas include increased muscle mass and strength (by elevating GH and subsequently IGF-1 levels), fat loss (as GH plays a role in lipolysis, the breakdown of fat), improved sleep quality (GH is naturally released in pulses during deep sleep), and anti-aging research (investigating potential improvements in skin elasticity, bone density, and overall vitality by restoring more youthful GH levels).
How It Works (Mechanisms Explained)
CJC-1295 works by mimicking the body's natural GHRH. It binds to receptors in the pituitary gland, signaling it to produce and release growth hormone. Unlike injecting synthetic GH directly, this method is considered more "biomimetic" because it preserves the natural, pulsatile release of GH, which is thought to be safer and more effective. The increase in GH then stimulates the liver to produce more IGF-1 (Insulin-like Growth Factor 1), which is responsible for many of the anabolic (growth-promoting) effects.
Common Research Stacks
CJC-1295 is almost always stacked with a GHRP (Growth Hormone Releasing Peptide), such as Ipamorelin or GHRP-2. This creates a synergistic effect because CJC-1295 (a GHRH) and Ipamorelin (a GHRP) stimulate GH release through two different pathways in the pituitary gland. Using them together creates a powerful synergistic effect, leading to a much larger release of GH than either could achieve alone.
Common Beginner Mistakes
The most critical mistake is confusing DAC vs. No DAC versions. CJC-1295 with DAC is injected infrequently (e.g., twice a week), while CJC-1295 without DAC must be injected multiple times per day to be effective. Using the wrong protocol for your version will lead to poor results or potential side effects. Other mistakes include ignoring cycling (continuous use can desensitize the pituitary gland—research protocols involve cycling periods), not monitoring bloodwork (IGF-1 levels should be monitored), and improper timing of injections (for the without DAC version, timing around workouts or before bed aligns with natural GH pulses).
Reconstitution Basics
CJC-1295 comes as a lyophilized powder requiring reconstitution with bacteriostatic water. The key consideration is which version you have (with or without DAC), as this determines your reconstitution volume and usage frequency. Once mixed, store refrigerated and use within 28 days. The with DAC version is more forgiving with storage due to its longer half-life, while the without DAC version requires more frequent preparation and precise timing.
