Quick math example
A 10 mg blended vial mixed with 2 mL gives 5,000 mcg/mL of total peptide. A 250 mcg dose is 0.05 mL, or 5 units on a U-100 syringe.
How the blend calculation works
CJC-1295 and Ipamorelin are often sold pre-blended in a single vial, with the label listing the total milligram amount across both compounds. Concentration math uses that total figure.
Once concentration is known, the draw volume for any target dose is straightforward division.
- 10 mg blend = 10,000 mcg total
- 10,000 mcg / 2 mL = 5,000 mcg per mL
- 250 mcg target = 0.05 mL draw
Note on labelled ratios
Blended vials are typically labelled as a 1:1 ratio of CJC-1295 to Ipamorelin, but check your specific label. The calculator works on the total peptide mass; if your protocol calls for a specific component dose, work from the labelled ratio first.
Frequently asked questions
Is CJC-1295 the same as CJC-1295 with DAC?+
No. CJC-1295 with DAC has a longer half-life, while CJC-1295 without DAC (sometimes called Mod GRF 1-29) is shorter-acting. Confirm which one your vial contains before calculating.
How does the calculator handle a 1:1 blend?+
It uses the total milligrams listed on the vial. If you need a CJC-only or Ipamorelin-only dose, divide your target by the labelled ratio before entering it.
What syringe should I use for small GH-peptide doses?+
Smaller draws are easier to read on a U-100 insulin syringe. The exact syringe is a setup choice; the calculator returns units for whichever you select.
