The Most Potent GH Secretagogue Stack. Maximum Pulse. Maximum Amplification.
peptide sciences coupon code You’ve researched growth hormone secretagogues. You know Mod GRF (CJC-1295 No DAC) amplifies GH pulses. You know GHRP-2 is potent. But Hexarelin? It’s in a league of its own.
Hexarelin is the most potent GHRP ever developed — stronger than GHRP-2, stronger than GHRP-6, stronger than Ipamorelin. It produces the highest peak GH release of any GHRP, with a unique receptor binding profile that resists desensitization.
The Mod GRF, Hexarelin 10mg (Blend) combines:
-
Mod GRF (Modified GRF / CJC-1295 No DAC) for GH pulse amplification
-
Hexarelin for maximum-potency GH initiation
This is the most powerful two-peptide GH secretagogue stack available. For researchers who need the highest possible GH output, this is your tool.
Let’s break down the peptide science behind this ultra-potent combination.
What’s Actually in the Vial?
Straight facts. No mystery fillers.
| Component | Amount | Role |
|---|---|---|
| Mod GRF (Modified GRF / CJC-1295 No DAC) | 5mg | GHRH analog → amplifies GH pulse |
| Hexarelin | 5mg | Ultra-potent GHRP → maximum GH initiation |
| 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.

Why This Blend? (The Enthusiast Take)
You could buy Mod GRF and Hexarelin separately. But here’s why the blend makes sense — especially for maximum GH output research.
Mod GRF (Modified GRF / 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.
Hexarelin is unique among GHRPs. It’s the most potent milligram for milligram — even stronger than GHRP-2. But here’s what makes Hexarelin different: it resists downregulation. Most GHRPs lose effectiveness with repeated use due to receptor desensitization. Hexarelin maintains its potency over longer research protocols.
Together: Hexarelin initiates the most powerful GH spike available. Mod GRF amplifies that spike even further. The result is the highest possible GH pulse from any two-peptide secretagogue stack — with better sustainability over time.
Why Mod GRF (No DAC) instead of CJC with DAC? DAC (Drug Affinity Complex) extends half-life to days, which flattens natural GH pulsatility. Mod GRF (No DAC) means a sharp pulse followed by clean return to baseline — ideal for studying peak amplitude.
Why Hexarelin over GHRP-2 or GHRP-6? Maximum potency. If your research question is about the absolute highest GH output, Hexarelin is your answer.
That’s not speculation. That’s published peptide sciences coupon code
The Technical Expert Breakdown (Still Friendly)
For those who want mechanisms without the lecture:
Mod GRF (Modified GRF / CJC-1295 No DAC) – GHRH analog
-
Also known as CJC-1295 without Drug Affinity Complex
-
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
-
Synergizes with any GHRP for greater GH output
Hexarelin – Ultra-potent GHRP
-
Binds to ghrelin (GHS-R1a) receptors with high affinity
-
Most potent GHRP available (stronger than GHRP-2)
-
Resists receptor desensitization (maintains efficacy over time)
-
Sharp peak GH release within 30-45 minutes
-
Moderate prolactin and cortisol elevation (similar to GHRP-2)
-
Mild appetite stimulation (less than GHRP-6)
-
Unique cardioprotective properties in research models
Synergistic effect:
Hexarelin initiates the most powerful GH spike of any GHRP. Mod GRF amplifies that spike further. Together, they produce the highest possible GH pulse from a two-peptide combination — with better long-term efficacy than other GHRPs.
Peak amplitude comparison:
| Stack | Relative GH Peak Amplitude | Desensitization Risk |
|---|---|---|
| Mod GRF alone | 1x | None |
| GHRP-6 alone | 1-2x | Moderate |
| GHRP-2 alone | 3-4x | Moderate |
| Ipamorelin alone | 2-3x | Low |
| Mod GRF + GHRP-2 | 6-8x | Moderate |
| Mod GRF + Hexarelin | 8-10x | Low |
That’s the kind of peptide science that makes this blend unique for advanced research.
Mod GRF vs. Hexarelin: Distinct Roles
| Peptide | Primary Mechanism | Unique Advantage |
|---|---|---|
| Mod GRF | Amplifies existing GH signals | Clean pulsatile amplification |
| Hexarelin | Initiates maximum GH release | Resists desensitization |
Together, they create the highest possible GH output with better sustainability than other GHRPs.
Reconstitution & Dosing (Laid-Back Version)
Simple. Straightforward. But note: Hexarelin is potent — start low.
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 Mod GRF
→ 250mcg Hexarelin
Common dosing for research protocols (start lower with Hexarelin):
| Dose per peptide | Volume | Timing |
|---|---|---|
| 50mcg each | 2 units (0.02ml) | 1-2x daily (starting dose) |
| 100mcg each | 4 units (0.04ml) | 1-2x daily |
| 150mcg each | 6 units (0.06ml) | 1-2x daily |
| 200mcg each | 8 units (0.08ml) | 1x 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
Important Hexarelin note: Due to its potency, many researchers find once-daily dosing sufficient. Twice-daily protocols should use lower per-dose amounts.
Store in refrigerator after reconstitution. Use within 30 days.

Who Is This Blend For?
-
Advanced researchers studying maximum GH peak amplitude
-
Endocrinology labs examining GH pulse kinetics
-
Researchers studying GH resistance (Hexarelin resists desensitization)
-
Exercise physiologists studying supramaximal GH response
-
Any study where the highest possible GH output is the primary variable
This blend is not for:
-
First-time peptide researchers (start with Mod GRF alone or with Ipamorelin)
-
Studies requiring zero prolactin/cortisol elevation (use Mod GRF + Ipamorelin)
-
Research protocols where cost is the primary constraint (Hexarelin is premium)
Hexarelin vs. Other GHRPs: Comparison
| Feature | GHRP-6 | GHRP-2 | Ipamorelin | Hexarelin |
|---|---|---|---|---|
| GH release potency | Moderate | High | Moderate | Highest |
| Prolactin elevation | Moderate | Mild | Very low | Mild-Moderate |
| Cortisol elevation | Moderate | Mild | Very low | Mild-Moderate |
| Appetite stimulation | High | Mild | None | Mild |
| Desensitization risk | Moderate | Moderate | Low | Lowest |
| Cardioprotective effects | No | No | No | Yes (research) |
| Best for | Appetite + GH | Max GH (short-term) | Clean data | Max GH (long-term) |
If your research demands maximum GH output over extended protocols, Hexarelin is the superior choice.
Mod GRF (No DAC) vs. With DAC: Comparison
| Feature | CJC-1295 (With DAC) | Mod GRF (No DAC) |
|---|---|---|
| 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 peak studies |
For peak amplitude research with Hexarelin, Mod GRF (No DAC) is the correct choice.

Frequently Asked Questions
Why Hexarelin over GHRP-2?
Hexarelin is more potent and, importantly, resists receptor desensitization. GHRP-2 can lose effectiveness over repeated use. Hexarelin maintains its potency longer.
Is Hexarelin safe for research?
Hexarelin is well-studied in research models. It has unique cardioprotective properties that other GHRPs do not share. However, it does cause mild-moderate prolactin and cortisol elevation — document these in your protocol.
What’s the difference in GH output between Hexarelin and GHRP-2?
Studies suggest Hexarelin produces approximately 20-30% higher peak GH levels than GHRP-2, with better sustainability over repeated dosing.
Can I use this blend for long-term research protocols?
Yes. Hexarelin’s resistance to desensitization makes it ideal for longer studies where other GHRPs might lose efficacy. Monitor prolactin and cortisol as with any GHRP.
How long does one 10mg vial last?
>At 50mcg of each, once daily: ~100 days.
>At 100mcg of each, once daily: ~50 days.
>At 100mcg of each, twice daily: ~25 days.
>At 150mcg of each, once daily: ~33 days.
Why empty stomach?
Glucose and insulin suppress GH release. Even small meals can blunt the pulse. For maximum peak amplitude with Hexarelin, fasting is essential.
What’s the peak research window for GH with this blend?
Peak GH levels occur approximately 30-45 minutes after administration. Return to baseline occurs within 2-3 hours.
