Calculate exact syringe units for your CJC-1295 + Ipamorelin blend vial. Enter the milligrams of each peptide, BAC water volume, and target dose for either component - the calculator shows the precise draw plus how much of the other peptide you receive. Covers no-DAC (Mod GRF 1-29) blends in 2 mg-10 mg vials with loading through maintenance dosing.
A blend vial holding 5 mg of CJC-1295 without DAC and 5 mg of ipamorelin — 10 mg total — reconstituted with 2 mL of bacteriostatic water gives 2.5 mg/mL of each component (5 mg/mL total peptide), or 25 mcg of each per unit on a U-100 syringe (50 mcg total per unit). For a 100 mcg + 100 mcg dose, draw the syringe to 4 units (0.04 mL); that single draw delivers 0.1 mg of CJC-1295 and 0.1 mg of ipamorelin, because the vial is filled 1:1. At that dose the vial provides about 50 doses.
| Peptide | Vial Amount | Concentration | Dose per Draw | Doses from Vial |
|---|---|---|---|---|
| CJC-1295 (no DAC) | 2 mg | 1000.0 mcg/mL | 100.0 mcg | 20 |
| Ipamorelin ★ | 2 mg | 1000.0 mcg/mL | 100.0 mcg | 20 |
The CJC-1295 + Ipamorelin stack combines a GHRH analogue (CJC-1295 no-DAC / Mod GRF 1-29) with a selective GHRP (ipamorelin). CJC-1295 stimulates the GHRH receptor while ipamorelin triggers GH release through the ghrelin receptor - synergistically amplifying growth hormone pulses without raising cortisol or prolactin.
| Protocol | CJC-1295 Dose | Ipamorelin Dose | Frequency | Timing | Duration |
|---|---|---|---|---|---|
| Lower-dose | 100 mcg | 100 mcg | 1× daily | Pre-bed, fasted | 8-12 weeks |
| Standard | 100 mcg | 100 mcg | 2× daily | Morning + pre-bed | 8-12 weeks |
| Higher-dose | 300 mcg | 300 mcg | 1-2× daily | Pre-bed ± morning | 8-12 weeks |
| Split dose | 100 mcg | 200 mcg | 2× daily | Morning + pre-bed | 8-12 weeks |
| 5-on-2-off | 100-300 mcg | 100-300 mcg | 5 days on / 2 off | Pre-bed | 12-16 weeks |
Timing on an empty stomach is important - insulin blunts GH release. Most protocols recommend 2-3 hours fasted before injection. Pre-bed injection aligns with natural GH pulse peaks during sleep.
| Factor | Pre-Made Blend Vial | Separate Vials |
|---|---|---|
| Convenience | Single draw per dose | Two draws (or combined syringe draw) |
| Dose flexibility | Fixed ratio - cannot adjust individual peptides | Full independent control |
| Cross-contamination risk | None (factory combined) | Minimal with proper technique |
| Cost | Often slightly cheaper per combined mg | May be cheaper if buying bulk single vials |
| Vendor availability | Most vendors carry CJC/Ipa blends | Universal availability |
| Calculator | Blend Calculator (this page) | Standard Peptide Calculator (per peptide) |
| Blend Vial | BAC Water | CJC Conc. | Ipa Conc. | 100+100 mcg Draw |
|---|---|---|---|---|
| 2 mg + 2 mg | 1 mL | 2 mg/mL | 2 mg/mL | 5 units |
| 2 mg + 2 mg | 2 mL | 1 mg/mL | 1 mg/mL | 10 units |
| 6 mg + 6 mg | 2 mL | 3 mg/mL | 3 mg/mL | ~3.3 units |
| 6 mg + 6 mg | 3 mL | 2 mg/mL | 2 mg/mL | 5 units |
| 6 mg + 6 mg | 6 mL | 1 mg/mL | 1 mg/mL | 10 units |
| 10 mg + 10 mg | 5 mL | 2 mg/mL | 2 mg/mL | 5 units |
| 10 mg + 10 mg | 10 mL | 1 mg/mL | 1 mg/mL | 10 units |
The steps below are generic peptide handling, the same for a blend vial and for either single vial; neither compound has an approved label, so no regulator specifies a diluent volume for either.
If you run the two compounds from separate vials, the arithmetic is the same for each. The table below shows it for a 5 mg single vial with 2 mL of bacteriostatic water, at the 300 mcg reference quantity this page already uses; it is arithmetic only, not a dose, and Peptigrity does not recommend a dose.
| Single vial | BAC Water | Concentration | 300 mcg Draw |
|---|---|---|---|
| CJC-1295 (no DAC), 5 mg | 2 mL | 2,500 mcg/mL | 0.12 mL (12 units) |
| Ipamorelin, 5 mg | 2 mL | 2,500 mcg/mL | 0.12 mL (12 units) |
A pre-blended 5 mg + 5 mg vial in 2 mL gives 5 mg/mL total peptide, 2,500 mcg/mL of each compound — the example worked through at the top of this page. Pre-blended vials are convenient but reduce dose flexibility: you cannot independently adjust the dose of each compound. Both compounds are given by subcutaneous injection, and neither requires injection near a specific tissue; general technique, including site choice, is in how to inject peptides, and the physical procedure in reconstituting peptides step by step.
“CJC-1295” refers to two distinct molecules in the peptide marketplace:
| Property | CJC-1295 no-DAC (Mod GRF 1-29) | CJC-1295 with DAC |
|---|---|---|
| Half-life | ~30 minutes | ~8 days |
| GH release pattern | Pulsatile (mimics natural) | Sustained, non-pulsatile |
| Dosing frequency | 1-2× daily | 1-2× weekly |
| Blend vial usage | Standard in CJC/Ipa blends | Rarely blended; typically sold standalone |
| Community preference | Strongly preferred | Niche use |
Important: Blend vials labeled “CJC-1295 + Ipamorelin” almost always contain the no-DAC version (Mod GRF 1-29). The calculator on this page is designed for no-DAC blends. If your vial contains CJC-1295 with DAC, the dosing frequency and protocol differ significantly.
| Blend Vial | 100+100 mcg 1×/day | 100+100 mcg 2×/day | 300+300 mcg 1×/day |
|---|---|---|---|
| 2 mg + 2 mg | 20 days ✅ | 10 days ✅ | ~6.6 days ✅ |
| 6 mg + 6 mg | 60 days ⚠️ | 30 days ⚠️ | 20 days ✅ |
| 10 mg + 10 mg | 100 days ⚠️ | 50 days ⚠️ | ~33 days ⚠️ |
Larger vials at conservative doses easily exceed the 28-day stability window. Choose vial size to match your protocol, or consider partial reconstitution. See how to store peptides.
A quality CJC-1295/Ipamorelin blend should show two distinct HPLC peaks on the CoA - one for each peptide. CJC-1295 (no-DAC) has MW of approximately 3,367 Da and ipamorelin approximately 711 Da. Mass spectrometry should confirm both molecular weights. Cross-reference with independent lab test results.
It depends on vial composition and BAC water. For a 6 mg + 6 mg blend with 3 mL BAC: 100 mcg CJC + 100 mcg Ipa = 5 units. Use the calculator at the top for your specific vial.
The commonly cited amount is 100 mcg CJC-1295 + 100 mcg ipamorelin, 1–2× daily. Higher-dose protocols cite up to 300 mcg of each. Protocols usually describe injecting on an empty stomach, often before bed. Peptigrity does not recommend a dose.
No-DAC (Mod GRF 1-29) is standard for blend vials and produces pulsatile GH release. DAC has an 8-day half-life and produces sustained, non-pulsatile elevation - used only in specific protocols.
Yes - draw both into the same syringe from separate vials. Pre-made blend vials are more convenient and eliminate cross-contamination risk.
Pre-bed on an empty stomach (2-3 hours fasted). GH pulses peak during sleep. For 2×/day protocols, add a fasted morning injection.
A 6+6 mg vial at 100+100 mcg once daily = 60 days - exceeds the 28-day stability window. At 300+300 mcg daily = 20 days, which fits. Match vial size to your protocol.
Both are GHRH(1-29) based. CJC-1295 has 4 amino acid substitutions for DPP-IV resistance, giving a ~30 min half-life vs sermorelin's ~10-20 min. CJC-1295 is considered the more stable version. See the tesamorelin calculator for a full GHRH comparison.
