2 mg vial

CJC-1295: a 2 mg vial

What a 2 mg vial of CJC-1295 becomes once it is mixed, and what each dose reported in the sources draws to on a syringe. Every figure is arithmetic on the vial size in the heading — none of it is a recommendation, and the doses are the ones our sources describe rather than ones we picked.

Leading with

2 mg + 2 mL bacteriostatic water = 1 mg/mL

Chosen because it puts the reported doses on readable marks of a 1 mL U-100 syringe. Other volumes are perfectly valid — the dilution table further down covers them, and the concentration changes what every dose draws to.

What each reported dose draws to

At 1 mg/mL, on a 1 mL U-100 syringe. Every row names the source it came from, and a trial protocol and a community convention are not the same kind of information.

Reported doses for CJC-1295, converted to syringe units for a 2 mg vial.
Goal	Dose	Units	Doses in this vial	Source
Non-DAC, commonly describedOne to three times daily · Subcutaneous	100 mcg – 300 mcg	10 units – 30 units	20	Community practice
With DAC, commonly describedOnce or twice weekly · Subcutaneous	1 mg – 2 mg	from 100 unitstop of the range needs a second vial	2	Community practice

Check every figure against the vial in front of you before drawing. Vials are filled with an overage and labels are not a guarantee. Change any of these numbers in the calculator.

If you add a different amount of water

The same 2 mg of compound, at four common volumes. More water means a larger, easier-to-measure draw of a weaker solution; less water means the opposite. The amount of compound you inject is identical in every row — only the volume carrying it changes.

Storage

Before mixing

Refrigerated at 2–8 °C, protected from light.

After mixing

Refrigerated at 2–8 °C. Do not freeze once mixed.

Arithmetic on the vial size named above and the doses our sources report. Nothing here is a recommendation, a protocol or medical advice, and no clinician has reviewed it. Some rows describe community practice, which is not evidence that a dose is safe or effective. Speak to a licensed healthcare provider before acting on any of it.
