What is it? CJC-1295 is a peptide that signals your pituitary gland to release growth hormone. It amplifies and extends GH pulses.
Two versions exist: CJC-1295 with DAC (long-acting, 1-2x weekly) and without DAC (short-acting, 2-3x daily). They work differently!
Key point: Most people use the "no DAC" version (also called Mod GRF 1-29) and stack it with Ipamorelin for best results.
DAC vs No DAC: Which Should You Use?
CJC-1295 NO DAC
(Also called Mod GRF 1-29)
- Short half-life (~30 min)
- Inject 2-3x daily (with Ipamorelin)
- Mimics natural GH pulses
- Most popular choice
CJC-1295 WITH DAC
(Drug Affinity Complex)
- ~ Long half-life (~6-8 days)
- ~ Inject 1-2x per week
- ~ Constant GH elevation (less natural)
- ~ Fewer injections, but blunts pulses
Recommendation: Most people prefer no DAC because it creates natural-looking GH pulses and stacks better with Ipamorelin.

CJC-1295 + Ipamorelin Stack Protocol
The most popular GH peptide stack. Here's how to use them together:
Standard Stack Protocol
| Peptide | Dose | Frequency |
|---|---|---|
| CJC-1295 (no DAC) | 100 mcg | 2-3x daily |
| Ipamorelin | 100-200 mcg | 2-3x daily (same time) |
Can I mix them together?
Yes! You can draw both into the same syringe. This reduces injections from 6 per day to 3.
Why stack them?
Ipamorelin triggers GH release. CJC-1295 amplifies and extends it. Together = bigger, longer GH pulses.
Frequently Asked Questions
DAC (Drug Affinity Complex) is a modification that extends the half-life dramatically:
- No DAC: Half-life ~30 minutes. Inject 2-3x daily. Creates natural GH pulses.
- With DAC: Half-life ~6-8 days. Inject 1-2x weekly. Creates constant GH elevation.
Most people prefer no DAC because pulsatile GH release is more natural and it synergizes better with Ipamorelin.
CJC-1295 (no DAC) works much better when stacked with a GHRP like Ipamorelin. Here's why:
- CJC-1295 is a GHRH analog - it amplifies GH release
- But it needs something to trigger that release first
- Ipamorelin provides that trigger
Think of it like this: Ipamorelin starts the car, CJC-1295 hits the gas. Together they're much more effective than either alone.
Mod GRF 1-29 is the same thing as CJC-1295 without DAC. It's also called "Modified GRF" or sometimes just "CJC" (confusingly).
The names refer to the same peptide - a modified version of the first 29 amino acids of GHRH. It's modified to resist breakdown and last ~30 minutes instead of just a few minutes.
Same timing rules as Ipamorelin - on an empty stomach:
- Morning: Immediately upon waking, before breakfast
- Pre-workout: 30-60 min before training (optional, if fasted)
- Before bed: 30+ min after last meal
Wait 30 minutes after injection before eating.
