CJC-1295 + Ipamorelin blend calculator
5 mg CJC-1295 + 5 mg Ipamorelin (10 mg total)
1 mg = 1000 mcg.
Enter your water volume and the amount you want, and this shows where to pull.
Blends come as one vial with a fixed mix, so every draw carries both compounds in this ratio. Running two separate vials? That is a stack: see the CJC-1295 + Ipamorelin stack page.
For tracking and calculation purposes only. Not medical advice. Based on a standard U-100 insulin syringe.
This calculator has no pre-filled amount for this blend. We pre-fill an amount only from an approved label or a human trial arm that fits this tool, and none does.

How the units are worked out
Your vial holds a fixed amount of peptide. The water you add sets the concentration (how much peptide sits in each millilitre). The concentration then decides how much liquid carries your dose.
Three steps, in order:
- Concentration (mcg/mL) = peptide in the vial (mcg) divided by water added (mL).
- Volume (mL) = your dose (mcg) divided by the concentration (mcg/mL).
- Units to draw = volume (mL) multiplied by 100.
That last step is the syringe, not the peptide. A U-100 insulin syringe is marked so 100 units hold 1 mL, so 0.1 mL reads as 10 units.
A worked example
Enter your dose in the calculator above and this line shows the numbers worked through.
Water and units at a glance
The vial sizes CJC-1295 + Ipamorelin: The Growth Hormone Stack is sold in, at different water volumes, with CJC-1295 as the amount you name. Every row opens the calculator on that mix.
Units appear once you enter a dose.
Composition as sold by vendors in our register; most-used water from WPA dosing data, Aug 2026. There is no pre-filled amount. Not a recommendation.
Mixing and storage
Run the water down the inside wall of the vial and let the powder dissolve on its own. Never shake it. Label the vial with the compound, the total mass, the water you added, the concentration and the date. A sealed freeze-dried vial keeps 12 to 24 months in the fridge at 2 to 8°C. Once mixed with preserved water, such as bacteriostatic water, that drops to roughly 28 days refrigerated. Keep it at the back of the fridge, away from light and away from the door's temperature swings.

Questions
Can I start with lower doses and titrate up?
How long before I see recovery differences in training?
What if I feel tingling in my fingers or carpal tunnel pain?
Can I stack this with other compounds like BPC-157 or TB-500?
What happens if I miss a dose of Ipamorelin?
Do I need bloodwork during the cycle?
