CJC-1295 no DAC / GHRP-6 Blend
CJC + GHRP-6
CJC-1295 no DAC / GHRP-6 Blend is a pre-mixed growth hormone secretagogue combination that pairs Modified GRF(1-29) with the original and most appetite-stimulating GHRP. This blend produces powerful pulsatile GH release through dual-receptor activation while delivering the strongest hunger drive of any GH peptide stack. GHRP-6 was the first synthetic ghrelin mimetic developed and remains the go-to GHRP for users who need or want significant appetite stimulation alongside GH optimization.
Starting dose. 100mcg CJC + 100mcg GHRP-6 per injection

How it works
This blend works through dual-receptor stimulation of the GH axis with pronounced ghrelin-mediated appetite effects:
CJC-1295 no DAC (Mod GRF 1-29)
Binds GHRH receptors on pituitary somatotrophs, activating the cAMP/PKA signaling cascade to prime and release stored GH granules. The four amino acid substitutions protect against DPP-IV degradation, extending the half-life to approximately 30 minutes. Produces acute GH pulses preserving natural pulsatile patterns.
GHRP-6
Binds GHS-R1a (ghrelin receptor) on the pituitary with strong efficacy, triggering GH release through the PLC/IP3/PKC pathway. GHRP-6 has the strongest orexigenic effect of any GHRP because it activates hypothalamic appetite centers more potently than GHRP-2 or Ipamorelin. It also suppresses somatostatin, removing the natural brake on GH secretion. GHRP-6 elevates cortisol and prolactin in a dose-dependent manner - more than Ipamorelin, less than Hexarelin.
Synergistic Amplification
The simultaneous GHRH signal (CJC) and GHRP signal (GHRP-6) converge through independent intracellular pathways, producing GH pulses 3-5x greater than either peptide alone. This mimics the body's natural dual-signal GH regulation system.
Appetite Mechanism
GHRP-6 activates neuropeptide Y (NPY) and agouti-related peptide (AgRP) neurons in the arcuate nucleus of the hypothalamus, triggering strong hunger signaling within 15-20 minutes of injection. This is the same pathway activated by endogenous ghrelin before meals.
What to expect
Days 1-7: Strong appetite stimulation is the first and most obvious effect, peaking 15-20 minutes post-injection. Use this hunger window to time your largest meals. Improved sleep quality with deeper slow-wave sleep, especially with bedtime dosing. Possible mild water retention. Transient flushing or tingling post-injection is normal.
Weeks 2-6: Body composition changes visible with adequate caloric intake. Muscle fullness and recovery improving. Skin quality starting to improve. Appetite effect becomes predictable and can be strategically timed around training and meals. Fat distribution may shift as GH levels optimize.
Weeks 6-12: Full body recomposition effects when paired with training and nutrition. Lean mass gains consolidated. Skin, hair, and connective tissue improvements visible. Consider cycling off after 8-12 weeks with a 4-week break to maintain pituitary sensitivity and prevent GHS-R1a desensitization.
Evidence
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 100 mcg CJC + 100 mcg GHRP-6 SubQ 2-3 times daily while fasted. No checked abstract administered this exact fixed combination, ratio, SubQ dose, or frequency in humans.
Mechanism and claimed 3-5× GH-pulse synergy for the exact blend. GHRP-6 or DAC-CJC-1295 component evidence cannot establish the mechanism magnitude, formulation, or pharmacodynamics of this exact no-DAC fixed blend.
Primary safety concern, including appetite, cortisol, and prolactin effects for the blend. No checked human abstract evaluated safety of the exact fixed blend at the displayed regimen; component-only safety was not transferred.
The honest take
Strongest appetite stimulation of any GH peptide blend
SupportedWell-supported by human comparative data. GHRP-6 consistently produces the most intense hunger response among GHRPs, peaking at 15-20 minutes post-injection. This is due to stronger hypothalamic NPY/AgRP activation compared to GHRP-2 or Ipamorelin.
Supported by GHRH + GHRP co-administration studies. The synergistic effect is well-established in the literature, though exact magnitude varies by individual and dose.
Practically validated. The 15-20 minute onset and 30-60 minute duration of appetite stimulation is consistent across users, making it predictable enough for meal timing strategies.
Interactions & stacking
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Documented together
Keep separate
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
Side effects & safety
Commonly reported
- Strong appetite increase 15-20 min post-injection lasting 30-60 min
- Transient flushing or warmth post-injection (resolves in minutes)
- Mild tingling or head rush immediately after injection
- Mild water retention in first 1-2 weeks
- Vivid dreams and improved sleep (desired effect)
Less common & notes
- At higher GHRP-6 doses (above 200mcg), cortisol and prolactin elevation becomes more significant.
- This can manifest as mild anxiety, irritability, or lethargy post-injection.
- GHRP-6 has the strongest appetite effect of any GHRP - some users find the hunger unmanageable if not strategically planned.
- Occasional stomach gurgling or GI discomfort from the ghrelin activation.
- Keep individual GHRP-6 doses at or below 200mcg to balance GH output against hormonal side effects.
- Both components have reasonable safety data, but long-term human combination studies are limited.
Pharmacokinetics
CJC-1295 no DAC: ~30 min; GHRP-6: ~20 min. Combined GH pulse duration: 1.5-2 hours.
CJC: 15-30 min; GHRP-6: 15-20 min. Peak synergistic GH release at ~20-30 min post-injection.
Both components cleared within 2-3 hours. GH pulse elevation returns to baseline by 3-4 hours.
SubQ: ~95-100% for both components. Oral: not viable (peptide degradation in GI tract).
GH pulse lasts 1.5-2 hours. Downstream IGF-1 elevation persists 12-20 hours. Appetite effect from GHRP-6 lasts 30-60 minutes post-injection, peaking at 15-20 minutes.
Enzymatic degradation by peptidases. CJC modifications provide DPP-IV resistance. GHRP-6 cleared primarily by renal and hepatic peptidases.
Storage. Store lyophilized vial at room temperature or refrigerated. After reconstitution with bacteriostatic water, store refrigerated at 2-8 degrees C. Use within 28-30 days of reconstitution. Do not freeze after reconstitution. Protect from prolonged light exposure. Discard if solution becomes cloudy or contains particulate matter.
