How many units is 300 mcg of CJC-1295 / Ipamorelin blend?

It depends entirely on how much water you added. In a 10 mg vial reconstituted with 2 mL, the concentration is 5 mg/mL, so 300 mcg is 0.06 mL, which is 6 units on a U-100 insulin syringe. In the same vial with 1 mL of water it is 3 units, and with 3 mL it is 9 units.

How much bacteriostatic water for a 10 mg CJC-1295 / Ipamorelin blend vial?

2 mL is the usual choice. It gives 5 mg/mL, which puts the commonly reported range of 100 mcg to 600 mcg between roughly 2 and 12 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many doses are in a 10 mg vial?

Divide 10 by your dose. At 300 mcg that is 33 doses, which at once daily is 33 days.

How many units is 300 mcg of the CJC-1295 ipamorelin blend?

In a 10 mg blend vial with 2 mL of water, 6 units on a U-100 syringe. That draw contains 150 mcg of each peptide.

Can I dose the two peptides separately from a blend?

No. The ratio is fixed in the vial. If you want a different ratio you need two separate vials, and the calculator run once for each.

CJC-1295 / Ipamorelin blend dosage calculator

The blend vial is usually 5 mg of CJC-1295 and 5 mg of ipamorelin, 10 mg in total. Enter the total on the label and your total dose, and the page also splits it back into each peptide.

About the numbers above

This is the most common growth hormone secretagogue pairing: a GHRH analogue (CJC-1295, usually the no-DAC form) plus a ghrelin mimetic (ipamorelin). The two act on different receptors and are sold pre-mixed in a single vial so they can be drawn in one syringe.

The trap with blends is that the label gives the total, and both components are in a fixed ratio you cannot change. A 10 mg vial is normally 5 mg of each. Reconstituted with 2 mL it is 5,000 mcg of blend per mL, so a 300 mcg draw (6 units) delivers 150 mcg of CJC-1295 and 150 mcg of ipamorelin. Commonly reported doses are 200 to 300 mcg of total blend, one to three times daily.

What is in each draw

The vial is 5 mg CJC-1295 (no DAC) + 5 mg Ipamorelin, a fixed 1:1 ratio. Every draw contains all of them in that proportion. Split below for 10 mg in 2 mL (5 mg/mL). The per-component figures are inferred from the label ratio, not measured.

Draw	Total blend	CJC-1295 (no DAC)	Ipamorelin
5 units	0.25 mg	0.125 mg	0.125 mg
10 units	0.5 mg	0.25 mg	0.25 mg
15 units	0.75 mg	0.375 mg	0.375 mg
20 units	1 mg	0.5 mg	0.5 mg
25 units	1.25 mg	0.625 mg	0.625 mg
30 units	1.5 mg	0.75 mg	0.75 mg

A 10 mg vial at different water volumes

If the draw feels awkward to read, change the water rather than the dose. The dose stays the same; only the mark moves.

Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
10 mg	1 mL	10 mg/mL	0.03 mL	3 units	33
10 mg	2 mL	5 mg/mL	0.06 mL	6 units	33
10 mg	3 mL	3.33 mg/mL	0.09 mL	9 units	33
20 mg	1 mL	20 mg/mL	0.015 mL	1.5 units	66
20 mg	2 mL	10 mg/mL	0.03 mL	3 units	66
20 mg	3 mL	6.67 mg/mL	0.045 mL	4.5 units	66

All rows above assume a 300 mcg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

How long it stays in you

The half-life of CJC-1295 / Ipamorelin blend is about 2 hours. That is the time for the amount in your blood to halve, so after one half-life you are at 50 percent of the peak, after two you are at 25 percent, and after four you are at roughly 6 percent. This is why it is dosed daily or more often: by the next morning almost none of the previous dose is left, and there is no build-up from day to day.

How many units is 300 mcg of CJC-1295 / Ipamorelin blend?: It depends entirely on how much water you added. In a 10 mg vial reconstituted with 2 mL, the concentration is 5 mg/mL, so 300 mcg is 0.06 mL, which is 6 units on a U-100 insulin syringe.

Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many units is 300 mcg of the CJC-1295 ipamorelin blend?: In a 10 mg blend vial with 2 mL of water, 6 units on a U-100 syringe. That draw contains 150 mcg of each peptide.
Can I dose the two peptides separately from a blend?: No. The ratio is fixed in the vial. If you want a different ratio you need two separate vials, and the calculator run once for each.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
