# CJC-1295 + Ipamorelin: The Complete GH Secretagogue Stack Guide

CJC-1295 and Ipamorelin are two of the most commonly stacked GH secretagogues in the biohacking and performance community. Used individually they each have benefits — used together, they work synergistically to amplify natural growth hormone release in a way that mimics and extends the body's own pulsatile GH rhythm.
This guide explains exactly how they work, the critical difference between CJC-1295 with DAC and CJC-1295 without DAC (mod GRF 1-29), how to dose and time each compound, and what to expect at different stages of the protocol.
How GH Secretagogues Work
Before getting into the protocol, understanding the mechanism makes the dosing decisions make more sense.
CJC-1295 is a synthetic analog of Growth Hormone Releasing Hormone (GHRH). It binds to GHRH receptors on the pituitary gland and signals it to produce and release growth hormone. Think of it as the accelerator — it tells the pituitary "produce more GH now."
Ipamorelin is a Growth Hormone Releasing Peptide (GHRP). It works via ghrelin receptors and a different pathway to also stimulate GH release. It has a strong selectivity for GH without meaningfully raising cortisol or prolactin — one of the reasons it's considered one of the cleanest GHRPs available.
Why stack them: CJC-1295 + Ipamorelin hits two separate GH release pathways simultaneously. The combined stimulus produces a stronger, more sustained GH pulse than either compound alone. The synergy is well-documented and this combination is consistently among the most popular in research communities.
CJC-1295 with DAC vs Without DAC — A Critical Distinction
This is where most confusion begins. CJC-1295 comes in two forms and they behave very differently:
CJC-1295 with DAC (Drug Affinity Complex)
- Half-life: ~8 days
- Dosing frequency: Once weekly
- Effect: Maintains a sustained, elevated GH baseline throughout the week
- Mechanism: The DAC modification allows CJC-1295 to bind albumin in the blood, dramatically extending its circulation time
CJC-1295 without DAC (Mod GRF 1-29)
- Half-life: ~30 minutes
- Dosing frequency: Per injection (same time as Ipamorelin)
- Effect: Creates acute, pulsatile GH spikes — more closely mimics natural GH pulsatility
- Mechanism: Standard peptide clearance — peaks fast and clears fast
Which to choose?
Both are legitimate. The choice depends on your preference and goals:
Use CJC+DAC if:
- You prefer weekly convenience over multiple injections
- You want sustained GH elevation for lean mass and recomposition
- You're running Ipamorelin daily and want the DAC providing the steady-state baseline
Use mod GRF 1-29 (no DAC) if:
- You want more precise control over your GH pulses
- You prefer a more natural pulsatile pattern
- You're doing a strictly timed pre-bed or pre-workout protocol
Dosing Protocol
CJC-1295 with DAC + Ipamorelin
CJC-1295 with DAC:
- Starting dose: 1mg once weekly
- Advanced: Up to 2mg weekly, though most people find 1mg sufficient
- Inject subcutaneously, fasted state preferred
Ipamorelin:
- Starting dose: 100mcg per injection
- Optimal range: 100–200mcg per injection
- Frequency: 1–3x per day depending on goals
- Timing: Fasted state is critical — food within 1-2 hours blunts GH release significantly
Common Ipamorelin Timing Strategies
| Frequency | Timing | Best For |
|---|---|---|
| Once daily | Pre-bed (fasted) | Sleep optimization, recovery, anti-aging |
| Twice daily | AM fasted + pre-bed | Lean mass, body recomp, performance |
| Three times daily | AM fasted + pre-workout + pre-bed | Aggressive recomp, experienced users |
Most people doing a CJC+DAC weekly + Ipamorelin AM and PM is a highly effective and manageable approach.
CJC-1295 without DAC (Mod GRF 1-29) + Ipamorelin
With no-DAC CJC, you co-inject CJC and Ipamorelin together at each session:
- Mod GRF 1-29: 100–200mcg per injection
- Ipamorelin: 100–200mcg per injection
- Frequency: 2–3x daily, always fasted
- Timing: Same syringe or same session — they work synergistically at the same time
Full Protocol Example
CJC-1295 with DAC + Ipamorelin (weekly CJC, twice-daily Ipa):
| Day | CJC+DAC | Ipamorelin AM | Ipamorelin PM |
|---|---|---|---|
| Monday | 1mg subQ | 100mcg fasted | 100mcg pre-bed |
| Tuesday | — | 100mcg fasted | 100mcg pre-bed |
| Wednesday | — | 100mcg fasted | 100mcg pre-bed |
| Thursday | — | 100mcg fasted | 100mcg pre-bed |
| Friday | — | 100mcg fasted | 100mcg pre-bed |
| Saturday | — | 100mcg fasted | 100mcg pre-bed |
| Sunday | — | 100mcg fasted | 100mcg pre-bed |
Cycle length: 12–16 weeks is standard, followed by a 4–8 week break.
What to Expect (Phase by Phase)
Weeks 1–3: Adjustment
- Mild water retention and bloating (GH effect — settles by week 3-4)
- Morning joint stiffness or slight puffiness in hands (common, dose-related)
- Possible fatigue from stronger overnight GH pulses
- Some users notice improved sleep quality immediately
Weeks 3–8: Building Phase
- Improved recovery between workouts becomes noticeable
- Gradual lean mass improvements — this is not a fast-acting protocol
- Reduced body fat, particularly visceral fat with extended use
- Skin quality improvements (GH + IGF-1 effect on collagen)
- Increased hunger is common — your metabolism is running higher
Weeks 8–16: Full Effect
- Strength and endurance improvements compound
- Body composition changes become clearly visible
- Sleep quality, hair, and skin improvements often cited by long-term users
- Some users notice joint comfort improvements (IGF-1 has cartilage effects)
Side Effects and How to Manage Them
Water retention: Most common early on. Usually resolves by week 3-4. If persistent, slightly reduce Ipamorelin dose. Keeping carbs moderate helps.
