Per-compound reconstitution
Each compound is calculated on its own — different vials, different concentrations, different draws. Use these references, then run your exact numbers on each compound's calculator.
Ipamorelin reference
U-100 units to draw for each common Ipamorelin dose, by vial size, reconstituted with 2.5 mL of bacteriostatic water.
| Vial | Concentration | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 2 mg | 0.8 mg/mL | 12.5 u(0.13 mL) | 25 u(0.25 mL) | 37.5 u(0.38 mL) |
| 5 mg | 2 mg/mL | 5 u(0.05 mL) | 10 u(0.1 mL) | 15 u(0.15 mL) |

CJC-1295 (no DAC) reference
U-100 units to draw for each common CJC-1295 (no DAC) dose, by vial size, reconstituted with 2 mL of bacteriostatic water.
| Vial | Concentration | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 2 mg | 1 mg/mL | 10 u(0.1 mL) | 20 u(0.2 mL) | 30 u(0.3 mL) |

CJC-1295 / Ipamorelin blend dosage chart (pre-mixed vial)
Protocols for this pair are usually written per peptide, while a blend vial is labelled with the total. For a 1:1 vial the blend dose is double the per-peptide dose, so "100 mcg of each" is 200 mcg of blend. Amounts discussed in community protocols are most often 100 to 300 mcg of each peptide per injection, frequently once a day before bed. Neither peptide is an approved medicine and none of these figures comes from a label, so this page does not recommend a dose.
"5/5" or "5 mg + 5 mg" means 10 mg total in the vial. A vial sold as "5 mg blend" usually holds 5 mg total (2.5 mg of each), which is half the concentration at the same water volume — check which one your label shows before you draw.
- 10 mg (5 + 5) + 2 mL = 5 mg/mL → 200 mcg blend = 4 units
- 10 mg (5 + 5) + 3 mL = 3.33 mg/mL → 200 mcg blend = 6 units
- 5 mg (2.5 + 2.5) + 2 mL = 2.5 mg/mL → 200 mcg blend = 8 units

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100); “per vial” is how many of that dose the vial holds, before the small dead-space loss on each draw. Confirm against your own vial label, diluent, and clinician or pharmacy instructions.

How to reconstitute a CJC-1295 / Ipamorelin blend vial
A blend vial is reconstituted like any lyophilised peptide: wipe both stoppers with alcohol, draw the bacteriostatic water, and let it run slowly down the inside wall of the vial rather than onto the powder. Swirl gently or roll the vial until it is clear; do not shake it. Label the vial with the date and the water you added.
The water volume only changes how many units each dose takes, not the dose. With a 10 mg (5 + 5) vial, 2 mL keeps a 200 mcg blend dose at 4 units, which is hard to read on a 1 mL syringe; 3 mL moves it to 6 units, and a 0.3 mL syringe with half-unit marks makes small blend doses easier to measure.
- 10 mg vial + 2 mL = 5 mg/mL (every 1 unit = 50 mcg of blend)
- 10 mg vial + 3 mL = 3.33 mg/mL (every 3 units = 100 mcg of blend)
- 5 mg vial + 2 mL = 2.5 mg/mL (every 1 unit = 25 mcg of blend)
How the GHRP and GHRH pair
Ipamorelin (a GHRP) and CJC-1295 without DAC (a GHRH) are typically dosed together because they act on different pathways for a larger combined GH pulse. With two separate vials, each has its own concentration and draw — calculate them independently, then dose at the same time.
- Separate vials = separate concentrations and draws
- Often dosed together for a combined GH pulse
- If pre-blended, use the blend calculator at the top of this page
Two vials or one blend?
Some sources sell ipamorelin and CJC-1295 pre-mixed in a single vial labelled with a combined total; others sell them separately. For a single blended vial, enter the labelled total in the blend calculator at the top of this page so the maths matches the label. For two separate vials, use the per-compound tables and each peptide's own calculator.
- Two vials: calculate each compound separately
- One blended vial: use the blend calculator's combined total
- Confirm the labelled ratio before interpreting component amounts
