01BACKGROUND

Safe, Pulsatile Growth Hormone Secretion

Mod GRF 1-29 (Modified Growth Hormone Releasing Factor 1-29) is a synthetic analogue of naturally occurring GHRH. It is frequently, and sometimes confusingly, sold by peptide companies under the name "CJC-1295 No DAC."

Unlike the DAC version which causes an endless 8-day hormone bleed, Mod GRF 1-29 has a short half-life of 30 minutes. This creates one massive, sharp, natural pulse of growth hormone that mimics the body\'s natural rhythm, making it vastly safer and more effective for long-term anti-aging and athletic recovery.

02WHAT TO TRACK

Mechanisms of Action

01
🔬
The Synergistic Pulse
✓Binds to GHRH receptors, instructing the pituitary to release its stored growth hormone in one massive surge.. ✓Maintains the male-pattern pulsatile release of GH, preventing receptor desensitization
02
🔬
The Classic Biohacker Stack
✓By itself, Mod GRF 1-29 is only moderately effective. However, when administered simultaneously in the exact same syringe with a GHRP (like Ipamorelin), the effects are synergistic, amplifying the to
03WHAT TO TRACK

Clinical Dosing & Protocols

01
💉
Standard Dose
Subcutaneous injection 1 to 3 times per day.
02
🔬
Synergy Stack
Almost universally drawn into the same syringe as Ipamorelin for the "Classic Stack".
03
🔬
Timing Rule
Must be injected ≥2 hours after eating, and wait 30 minutes before eating again.

Vital Protocol FAQs

01
🔬
Why do companies call it CJC-1295 No DAC?
It’s a historical marketing mistake. True CJC-1295 fundamentally includes the DAC chemical modification. What is sold as "No DAC" is simply the base tetrasubstituted MOD GRF 1-29 peptide block. Always
02
⚠️
Does it have the same side effects as real HGH?
No. Because it relies on your pituitary to release its internal stores, the body regulates the massive extremes. You rarely experience the severe water retention, swelling, and insulin crushing side e
