CJC-1295 No DAC
CJC-1295 (without DAC) is a GHRH analogue that stimulates the pituitary gland to release growth hormone in natural pulsatile bursts. Without the DAC modification, it has a short half-life (~30 min), producing a clean GH pulse rather than sustained elevation. This makes timing critical — it must be used correctly to be effective.
Concentration reference
Standard mix: 5mg vial + 1mL BAC water = 5mg/mL. Each 0.06mL (6 IU) = 300mcg.
Dosing schedule
| Phase / Use | Dose | Draw Volume | Frequency | Notes |
|---|---|---|---|---|
| Beginner | 100mcg | 0.02mL (2 IU) | Once daily — pre-sleep | First 2 weeks — establish response |
| Standard | 200mcg | 0.04mL (4 IU) | Once daily — pre-sleep | Most common research dose |
| Advanced | 300mcg | 0.06mL (6 IU) | Twice daily — AM + pre-sleep | Maximum research dose |
| Stack — AM | 200mcg CJC + 200mcg Ipa | 0.04mL each | Upon waking, fasted | AM pulse — paired with Ipamorelin |
| Stack — PM | 200mcg CJC + 200mcg Ipa | 0.04mL each | 30–45 min pre-sleep, fasted | PM pulse — most effective GH release window |

Injection sites
Subcutaneous abdomen or outer thigh. No localized benefit — injection site does not affect GH pulse.
Timing
CRITICAL: Inject 30–45 minutes before sleep OR on an empty stomach (2+ hours post-meal). Eating carbohydrates within 2 hours of injection suppresses the GH response by up to 70%. Fasting state is essential.
Cycle length
8–12 weeks on, 4 weeks off. Allow pituitary to maintain natural sensitivity.
Stacking
Almost always paired 1:1 with Ipamorelin. CJC-1295 triggers GH release; Ipamorelin amplifies the pulse magnitude. They are synergistic — the combo produces significantly more GH than either alone.
Warnings
- ⚠Carbohydrates near injection time massively blunt GH response — fasting state is not optional for effective results
- ⚠Do not use DAC version (CJC-1295 with DAC) interchangeably — different half-life and dosing protocol
Tips
- ✔Pre-sleep injection is the single most effective timing — natural GH peaks during deep sleep, CJC amplifies this
- ✔Morning injection should also be fasted — take upon waking, wait 30–45 min before eating
