GHRH Meets GHRP. The Classic Growth Hormone Research Stack.
research peptides You’ve read the literature. You know that growth hormone releasing hormone (GHRH) analogs and growth hormone releasing peptides (GHRPs) work synergistically. One amplifies. One initiates. Together, they create a powerful pulse of endogenous growth hormone.
That’s the science behind the CJC-1295 (No DAC), GHRP-6 10mg (Blend) .
CJC-1295 (No DAC) is a synthetic GHRH analog that amplifies natural GH pulses. GHRP-6 is the original growth hormone releasing peptide — potent, well-studied, and reliable. Together in one vial? A 1:1 blend that represents decades of peptide science research. research peptides
Whether you’re studying muscle recovery, metabolic function, appetite regulation, or tissue repair, this classic stack delivers.
Let’s break down what’s inside — no fluff, just data.
What’s Actually in the Vial?
Straight facts. No mystery fillers.
| Component | Amount | Role |
|---|---|---|
| CJC-1295 (No DAC) | 5mg | GHRH analog → amplifies GH pulse |
| GHRP-6 (Growth Hormone Releasing Peptide-6) | 5mg | GHRP → initiates GH release |
| Total | 10mg | 1:1 ratio |
Lyophilized powder. Sterile. ≥99% purity. Third-party tested. Vacuum-sealed amber glass vial.
Two peptides. One vial. Balanced 1:1 ratio.
That’s smart peptide science.
Why This Blend? (The Enthusiast Take)
You could buy CJC-1295 and GHRP-6 separately. But here’s why the blend makes sense — especially if you’re studying appetite pathways alongside GH release. research peptides
CJC-1295 (No DAC) works on the GHRH receptor. It amplifies the natural growth hormone pulse your body already produces. Think of it as turning up the volume on your body’s GH signal.
GHRP-6 works on the ghrelin receptor. It directly stimulates the pituitary to release stored growth hormone — and it overcomes somatostatin’s natural inhibition. But here’s what makes GHRP-6 different from GHRP-2 or Ipamorelin: it significantly increases appetite through ghrelin receptor activation.
Together: GHRP-6 initiates GH release. CJC-1295 makes that release stronger and more sustained. The result is a synergistic GH pulse significantly larger than either peptide alone.
Why No DAC? DAC (Drug Affinity Complex) extends half-life to days. Sounds good, but it also flattens the natural pulsatile pattern of GH release. No DAC means a sharp pulse followed by a clean return to baseline — which more closely mimics natural physiology.
Why GHRP-6 over other GHRPs? If your research protocol involves studying appetite, food intake, or ghrelin pathways, GHRP-6 is the tool you want. Its hunger-stimulating effect is well-documented and reliable.
That’s not speculation. That’s published peptide science.
The Technical Expert Breakdown (Still Friendly)
For those who want mechanisms without the lecture:
CJC-1295 (No DAC) – GHRH analog
-
Binds to GHRH receptors on pituitary somatotrophs
-
Amplifies amplitude of endogenous GH pulses
-
No DAC = ~30-minute half-life → clean pulsatile release
-
Does not interfere with natural GH feedback loops
-
Shown to increase GH pulse magnitude without flattening rhythm
GHRP-6 (Growth Hormone Releasing Peptide-6)
-
Binds to ghrelin (GHS-R1a) receptors on pituitary and hypothalamus
-
Directly stimulates GH release from somatotrophs
-
Overcomes somatostatin inhibition
-
Potently increases appetite via ghrelin receptor activation in hypothalamus
-
Peak GH release within 30-45 minutes
-
Slightly higher prolactin/cortisol elevation than GHRP-2 or Ipamorelin
Synergistic effect:
GHRP-6 initiates GH release. CJC-1295 amplifies that release. Together, they produce a GH pulse significantly larger than the sum of their individual effects.
Unique to GHRP-6: The appetite-stimulating effect is a feature, not a bug — for researchers studying ghrelin pathways, cachexia, or metabolic disorders.
That’s the kind of peptide science that spans endocrinology, metabolism, and behavior.
Reconstitution & Dosing (Laid-Back Version)
Simple. Straightforward. No advanced degree required.
What you need:
-
Bacteriostatic water
-
Insulin syringe (0.5ml or 1ml, 30–31 gauge)
-
Alcohol wipes
Quick math:
Add 2ml of bacteriostatic water to the vial.
Now each 0.1ml (10 units on a 1ml syringe) contains:
→ 250mcg CJC-1295 (No DAC)
→ 250mcg GHRP-6
Common dosing for research protocols:
| Dose per peptide | Volume | Timing |
|---|---|---|
| 100mcg each | 4 units (0.04ml) | 1-3x daily |
| 150mcg each | 6 units (0.06ml) | 1-3x daily |
| 200mcg each | 8 units (0.08ml) | 1-2x daily |
| 250mcg each | 10 units (0.1ml) | 1-2x daily |
Best practice: Administer on an empty stomach (at least 2 hours after eating, 30 minutes before). GH release is suppressed by glucose and insulin.
Timing protocols:
-
Morning: Upon waking, before breakfast
-
Post-workout: After training, before eating
-
Bedtime: 30-60 minutes before sleep
-
Note: GHRP-6’s appetite effect peaks ~30 minutes after administration — factor this into your research protocol
Store in refrigerator after reconstitution. Use within 30 days.

Who Is This Blend For?
-
Researchers studying GH pulsatility and ghrelin pathways
-
Metabolism investigators looking at appetite and body composition
-
Cachexia researchers studying wasting syndromes
-
Exercise physiologists examining recovery and repair
-
Endocrinology researchers studying the GH/ghrelin axis
This blend is not for:
-
First-time peptide researchers (start with a single peptide)
-
Studies requiring minimal appetite effects (use GHRP-2 or Ipamorelin instead)
-
Anyone unfamiliar with ghrelin receptor pharmacology
GHRP-6 vs. GHRP-2 vs. Ipamorelin: Quick Comparison
| Feature | GHRP-6 | GHRP-2 | Ipamorelin |
|---|---|---|---|
| GH release potency | Moderate | High (2-3x GHRP-6) | Moderate |
| Prolactin elevation | Moderate | Low | Very low |
| Cortisol elevation | Moderate | Low | Very low |
| Hunger stimulation | High | Moderate | Very low |
| Best for | Appetite/GH studies | Pure GH research | Minimal side effects |
If your research protocol requires separating GH effects from appetite effects, choose GHRP-2 or Ipamorelin. If you’re studying ghrelin-mediated appetite or cachexia, GHRP-6 is your tool.
CJC-1295 (No DAC) vs. With DAC: Quick Comparison
| Feature | With DAC | No DAC (this blend) |
|---|---|---|
| Half-life | ~6-8 days | ~30 minutes |
| GH release pattern | Flattened, constant | Sharp pulse, return to baseline |
| Natural rhythm mimicry | Poor | Excellent |
| Risk of GH desensitization | Higher | Lower |
| Best for | Continuous elevation studies | Pulsatile rhythm studies |
For ghrelin and GH pulse research, No DAC is the correct choice.

Frequently Asked Questions
Why GHRP-6 over GHRP-2?
GHRP-6 is the original GHRP with the most published research. Its appetite-stimulating effect is a feature — useful for studying ghrelin pathways, cachexia, or metabolic disorders. GHRP-2 is more potent for pure GH research with fewer appetite effects.
Does GHRP-6 cause more side effects than other GHRPs?
GHRP-6 can cause slightly higher prolactin and cortisol elevation than GHRP-2 or Ipamorelin, but still within normal physiological ranges for most research applications. The most notable effect is increased appetite.
How soon does the appetite effect occur?
Peak hunger typically occurs 30-60 minutes after administration and subsides within 1-2 hours. Factor this into your research timing protocols.
Can I use this blend with other peptides?
Yes. Many researchers stack GH secretagogues with BPC-157, TB-500, or GHK-Cu for comprehensive recovery research. Just stagger administration times.
How long does one 10mg vial last?
>At 100mcg of each, twice daily: ~25 days.
>At 150mcg of each, twice daily: ~16 days.
>At 200mcg of each, twice daily: ~12 days.
Why empty stomach?
Glucose and insulin suppress GH release. Even small meals can blunt the pulse. GHRP-6’s appetite effect also means timing relative to meals is especially important.
What’s the peak research window for GH?
Peak GH levels occur approximately 30-45 minutes after administration. Return to baseline occurs within 2-3 hours. research peptides
