Description
CJC-1295 no DAC (often called Mod GRF 1-29) is a synthetic peptide that stimulates the pituitary gland to naturally produce Growth Hormone (GH). Unlike the DAC (Drug Affinity Complex) version, it has a short half-life (~30 minutes), which preserves the body’s natural pulsatile release rhythm.
Core Breakdown
-
- Function: Acts as a Growth Hormone-Releasing Hormone (GHRH) analog to boost GH and IGF-1 levels.
- The “No DAC” Difference: Without DAC, the peptide clears the body quickly. This means it requires frequent injections (often daily or twice daily) to mimic the body’s natural hormone pulses.
- Common Stacks: It is frequently paired with GH-releasing peptides like Ipamorelin to create a synergistic release of GH, maximizing effectiveness while minimizing side effects.
- Benefits: Commonly researched for promoting lean muscle mass, fat loss, improved sleep, and cellular repair.
- Side Effects: Potential mild side effects can include flushing, headaches, drowsiness, and localized injection site redness or pain.
Typical Dosing and Research Protocol
Because the “no DAC” version has a short window of active release, protocols generally focus on small, consistent dosing.
- Frequency: 1 to 2 times daily (often taken before bed or first thing in the morning).
- Synergy: Protocols frequently stack 100-200 mcg of CJC-1295 no DAC with an equal amount of Ipamorelin.
Ipamorelin is a selective, synthetic pentapeptide and growth hormone secretagogue that mimics the “hunger hormone” ghrelin. It works by stimulating the pituitary gland to release natural pulses of growth hormone (GH) without causing unwanted spikes in cortisol, prolactin, or appetite.
How It Works & Primary Uses
Ipamorelin binds to specific growth hormone secretagogue receptors (GHSR) in the hypothalamus and pituitary gland. It is widely discussed in regenerative and functional medicine for its targeted approach, which offers the benefits of increased GH without the side effects associated with older GH-releasing peptides (GHRPs) or direct human growth hormone injections.
-
- Body Composition: May support fat loss and the development of lean muscle mass by boosting metabolism and promoting lipolysis.
- Recovery & Sleep: Users often report improvements in sleep depth, workout recovery, and joint tissue repair.
Administration & Stacking
- Dosing: It is typically administered via subcutaneous injections once or twice daily (often before bed). Protocols usually cycle for 8 to 12 weeks.
- Synergy: It is frequently “stacked” with Growth Hormone Releasing Hormone (GHRH) analogs like CJC-1295. While ipamorelin triggers the pulse of GH, CJC-1295 increases the number of somatotrophs available to release GH, extending the duration of the effect
