# CJC-1295 + Ipamorelin: The Complete GH Secretagogue Stack Guide
> Note: PeptIQ is not a medical provider. The information in this article is for educational purposes only. Always consult a qualified healthcare professional before starting any peptide protocol.
Answer first: The standard research-community stack is CJC-1295 without DAC (Mod GRF 1-29) + Ipamorelin, often 100–200mcg each, co-injected 1–3x daily in a fasted window (pre-bed is the most common single pin). CJC with DAC is a different schedule (about 1–2mg weekly) and does not replace the pulsatile no-DAC + Ipamorelin pattern.
CJC-1295 and Ipamorelin are two of the most commonly stacked GH secretagogues. Used together, they hit separate receptors and amplify a GH pulse neither compound produces alone at the same magnitude.

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)
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

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

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.
Carpal tunnel / tingling in hands: Sign that GH is running high. Reduce Ipamorelin by 25-50mcg. This is dose-dependent and resolves quickly when you back off.
Increased hunger: Expected — your metabolism is faster. Use this as a signal to fuel appropriately with protein.
Fatigue from stronger GH pulses: Usually only in the first 2 weeks. Pre-bed dosing helps by timing the pulse to sleep rather than active hours.
Numbness in injection site: Normal — rotate sites (lower abdomen, thighs) to prevent buildup.
Stacking With Other Peptides
CJC-1295 + Ipamorelin pairs well with:
BPC-157: Excellent complement for recovery and joint health. Different mechanism — no interaction. Run simultaneously.
MOTS-C: Mitochondrial AMPK activation works synergistically with GH-mediated fat oxidation. Good combo for body recomp.
Tesamorelin: Another GHRH analog. Running both CJC+DAC and Tesamorelin simultaneously is redundant — pick one GHRH source. Tesamorelin has stronger visceral fat research specifically; CJC+DAC is more versatile.
GHK-Cu: Collagen, anti-aging, skin — complements the IGF-1 upregulation from the secretagogue stack.
Cycling and Long-Term Use
Running CJC-1295 + Ipamorelin continuously without breaks can downregulate pituitary sensitivity over time. Standard approach:
Cycle: 12–16 weeks on
Break: 4–8 weeks off (during this time, natural GH production returns to baseline)
Long-term: Many users run 2–3 cycles per year with good results
Bloodwork during and after cycle: IGF-1 is the primary marker to track. Fasting glucose is worth monitoring since GH can affect insulin sensitivity.
Frequently Asked Questions
Q: Can I mix CJC-1295 and Ipamorelin in the same syringe?
A: Yes — when using mod GRF 1-29 (no-DAC), mixing in the same syringe for injection is common and safe. For CJC+DAC (weekly shot), it's a separate injection from your daily Ipa.
Q: Do I need to fast before every injection?
A: Yes. Food raises insulin, and elevated insulin significantly blunts GH release. Fast at least 1.5–2 hours before any GHRP/GHRH injection. Pre-bed and pre-workout (fasted) are the most convenient windows.
Q: CJC-1295 with DAC vs mod GRF 1-29 — does one work better?
A: Different protocols, both work. DAC is more convenient (once weekly); mod GRF 1-29 gives more natural pulsatility. For most people doing a recomposition protocol with daily Ipamorelin, the DAC version is simpler without sacrificing results.
Q: How long until I see results?
A: Expect 4–6 weeks before body composition changes become visible. Sleep improvements often come first (weeks 1–2). The protocol rewards patience — GH-mediated recomp is slow and cumulative, not rapid like stimulants.
Q: Can I run this alongside a GLP-1 like Retatrutide or Tirzepatide?
A: Yes — these operate through different pathways. GLP-1s suppress appetite and improve insulin sensitivity; GH secretagogues optimize growth hormone signaling and lean mass. The combination is popular in the advanced recomp community. Monitor body weight trends and adjust calories intentionally — GLP-1 reduces appetite while GH increases metabolic demand.
Q: What's the difference between Ipamorelin and GHRP-2 or GHRP-6?
A: Ipamorelin is significantly more selective — it releases GH without meaningfully raising cortisol or prolactin. GHRP-2 is potent but raises cortisol. GHRP-6 causes significant hunger spikes. Ipamorelin is the cleanest starting point for most people.
