Amplified GH Release. High-Peak Potency. Two Peptides. One Vial.
verified peptides You’ve researched growth hormone secretagogues. You know that GHRH analogs and GHRPs work better together than apart. But not all combinations are the same.
If your research protocol demands maximum GH peak amplitude — the highest possible spike in growth hormone levels — this is your blend.
The Mod GRF, GHRP-2 10mg (Blend) combines:
-
Mod GRF (Modified GRF / CJC-1295 No DAC) for GH pulse amplification
-
GHRP-2 (Pralmorelin) for high-potency GH initiation
This is the most potent two-peptide GH secretagogue stack available. If you want to study high-amplitude GH pulses, this is your tool.
Let’s break down the verified peptides behind this powerful 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 |
| GHRP-2 (Pralmorelin) | 5mg | Potent GHRP → initiates high-peak 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 potent peptide science.
Why This Blend? (The Enthusiast Take)
You could buy Mod GRF and GHRP-2 separately. Many researchers do. But here’s why the blend makes sense — especially for high-amplitude GH 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 on your body’s GH signal.
GHRP-2 is the most potent GHRP milligram for milligram — about 2-3x stronger than GHRP-6. It directly stimulates the pituitary to release stored growth hormone and overcomes somatostatin’s natural inhibition.
Together: GHRP-2 initiates a sharp, high-amplitude GH spike. Mod GRF amplifies that spike even further. The result is the highest possible GH pulse from a two-peptide secretagogue stack.
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 GHRP-2 over other GHRPs? GHRP-2 is the most potent option. If your research question is about maximum GH output, GHRP-2 is your answer.
That’s not speculation. That’s published verified peptides
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
GHRP-2 (Pralmorelin) – Potent GHRP
-
Binds to ghrelin (GHS-R1a) receptors on pituitary and hypothalamus
-
2-3x more potent than GHRP-6 milligram for milligram
-
Directly stimulates GH release from somatotrophs
-
Overcomes somatostatin inhibition
-
Sharp peak GH release within 30-45 minutes
-
Mild prolactin and cortisol elevation (less than GHRP-6)
-
Mild appetite stimulation (less than GHRP-6)
Synergistic effect:
GHRP-2 initiates a high-amplitude GH spike. Mod GRF amplifies that spike further. Together, they produce the highest possible GH pulse from a two-peptide combination.
Peak amplitude comparison:
| Stack | Relative GH Peak Amplitude |
|---|---|
| Mod GRF alone | 1x (baseline amplification) |
| GHRP-2 alone | 3-4x |
| GHRP-6 alone | 1-2x |
| Ipamorelin alone | 2-3x |
| Mod GRF + GHRP-2 | 6-8x |
That’s the kind of peptide science that makes this blend unique.
Mod GRF vs. GHRP-2: Distinct Roles
| Peptide | Primary Mechanism | What It Does NOT Do |
|---|---|---|
| Mod GRF | Amplifies existing GH signals | No GH release on its own |
| GHRP-2 | Initiates high-peak GH release | No amplification on its own |
Together, they create a sum greater than their parts. That’s synergy.
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 Mod GRF
→ 250mcg GHRP-2
Common dosing for research protocols:
| Dose per peptide | Volume | Timing |
|---|---|---|
| 100mcg each | 4 units (0.04ml) | 1-2x daily |
| 150mcg each | 6 units (0.06ml) | 1-2x 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 (exercise enhances GH sensitivity)
-
Bedtime: 30-60 minutes before sleep (overlaps with natural nocturnal GH peak)
Note: Because this blend contains GHRP-2, there is mild prolactin, cortisol, and appetite elevation — though less than GHRP-6. Document these effects in your research protocol.
Store in refrigerator after reconstitution. Use within 30 days.

Frequently Asked Questions
Why Mod GRF instead of CJC-1295 with DAC?
For peak amplitude research, you want a sharp pulse, not a flattened elevation. Mod GRF (No DAC) provides a ~30-minute half-life that amplifies the GHRP-2 spike without flattening the return to baseline.
Is GHRP-2 stronger than GHRP-6?
Yes. GHRP-2 is approximately 2-3 times more potent milligram for milligram than GHRP-6, with fewer prolactin, cortisol, and appetite effects.
What are the side effect differences between GHRP-2 and Ipamorelin?
GHRP-2 causes mild prolactin, cortisol, and appetite elevation. Ipamorelin causes none. If your research requires zero confounding variables, use Mod GRF + Ipamorelin. If you need maximum GH output, use this blend.
Can I use this blend for long-term research protocols?
Yes, but monitor prolactin and cortisol if running extended studies. The mild elevation from GHRP-2 is generally well-tolerated but should be documented in your research notes.
How long does one 10mg vial last?
>At 100mcg of each, once daily: ~50 days.
>At 100mcg of each, twice daily: ~25 days.
>At 200mcg of each, once daily: ~25 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. For maximum peak amplitude, 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. This is a tighter, higher window than Ipamorelin.
Research Applications Summary
| Research Area | Primary Mechanism | Peak Timing |
|---|---|---|
| Max GH amplitude | GHRP-2 initiation + Mod GRF amplification | 30-45 minutes |
| Pulsatile kinetics | Sharp spike, clean return | 2-3 hours total |
| Exercise recovery | Post-training GH spike | 30-45 minutes post-injection |
| Aging/GH decline | Restoring youthful GH pulses | Morning or bedtime |
