What is CJC/IPA Blend?
The CJC/IPA Blend combines the two most popular growth hormone peptides in a single vial:
| Component | Amount | Type | Primary Action |
|---|---|---|---|
| CJC-1295 (no DAC) | 5mg | GHRH analog | Amplifies GH pulse |
| Ipamorelin | 5mg | GHRP | Initiates GH pulse |
This is the classic “GHRH + GHRP” combination that produces synergistic growth hormone release — significantly more effective than either peptide alone.
Quick Reference
| Parameter | Value |
|---|---|
| Total Peptide | 10mg (5mg CJC + 5mg Ipa) |
| Recommended BAC Water | 2mL |
| Resulting Concentration | 5mg/mL total |
| Component Concentration | 2.5mg/mL each |
| Typical Dose | 200-400mcg blend |
| Frequency | 2-3x daily |
The GHRH + GHRP Synergy
Why This Combination Works
| Component | Role | Analogy |
|---|---|---|
| Ipamorelin (GHRP) | Initiates GH pulse | ”Lights the match” |
| CJC-1295 (GHRH) | Amplifies GH pulse | ”Adds fuel to fire” |
| Together | Synergistic release | 1 + 1 = 3 |
Research shows the combination produces significantly more GH than either peptide alone.
Reconstitution Guide
Step-by-Step Instructions
- Clean vial stoppers — Wipe with alcohol swabs
- Draw 2mL BAC water — Using sterile syringe
- Add to peptide vial — Inject slowly down the wall
- Dissolve — Gently swirl, 2-5 minutes
- Label and refrigerate — Store immediately
Concentration Calculations
With 10mg blend (5+5) in 2mL BAC water:
- Total concentration: 5mg/mL
- CJC-1295: 2.5mg/mL
- Ipamorelin: 2.5mg/mL
- Per unit (U-100): 50mcg total (25mcg each)
Dosage Protocol
Common Dose Calculations
| Blend Dose | Draw Volume | Units | CJC-1295 | Ipamorelin |
|---|---|---|---|---|
| 200mcg | 0.04mL | 4 | 100mcg | 100mcg |
| 300mcg | 0.06mL | 6 | 150mcg | 150mcg |
| 400mcg | 0.08mL | 8 | 200mcg | 200mcg |
What You Get Per Dose
At 400mcg blend dose:
- CJC-1295: 200mcg (high-normal single dose)
- Ipamorelin: 200mcg (standard single dose)
Doses Per Vial
| Dose | Doses | At 2x/day | At 3x/day |
|---|---|---|---|
| 200mcg | 50 | 25 days | ~17 days |
| 300mcg | ~33 | ~16 days | ~11 days |
| 400mcg | 25 | ~12 days | ~8 days |
Suggested Protocols
Protocol A: Standard
- Dose: 200-300mcg blend
- Frequency: 2x daily (AM + before bed)
- Duration: 8-12 weeks
Protocol B: Enhanced
- Dose: 300-400mcg blend
- Frequency: 3x daily (AM, post-workout, before bed)
- Duration: 8-12 weeks
Timing Considerations
Optimal injection times:
- Morning (fasted) — First dose
- Post-workout — Optional second dose
- Before bed — Most important for GH pulse
Important:
- Always on empty stomach
- Wait 20-30 minutes before eating
- Avoid fatty foods before injection
Storage Requirements
| Form | Temperature | Duration |
|---|---|---|
| Lyophilized | -20°C | 2+ years |
| Reconstituted | 2-8°C | 3-4 weeks |
Research Considerations
Mechanism of Action
Ipamorelin (GHRP):
- Ghrelin receptor (GHS-R1a) binding
- Initiates GH release
- Clean profile (minimal cortisol/prolactin)
CJC-1295 no DAC (GHRH):
- GHRH receptor activation
- Amplifies the GH pulse
- ~30 minute half-life
Combined:
- Synergistic GH release
- More natural pulsatile pattern
- Enhanced IGF-1 elevation
Blend vs Separate Peptides
| Approach | Pros | Cons |
|---|---|---|
| Blend | Single injection, convenient | Fixed 1:1 ratio |
| Separate | Adjust ratios individually | Two vials, two draws |
Expected Research Outcomes
Studies on GHRH + GHRP combinations show:
- Significantly elevated GH peaks
- Increased IGF-1 levels
- Maintained pulsatile pattern
- Synergy greater than additive
