CJC-1295 / Ipamorelin Dosage: Units, Mixing and Cycle Protocol

CJC-1295 and Ipamorelin are research peptides often discussed as a paired blend in the literature. The math behind a dose has three moving parts: how much water you add, how concentrated that makes the vial, and how many syringe units that concentration works out to. This page covers the standard reference ranges, the 1 unit = 0.02 mg rule, and typical cycle framing. Numbers can be checked instantly in the CJC-1295 / Ipamorelin blend calculator.

The standard dosing range people reference

Across published protocols and supplier references, the commonly cited per-dose figure for the blend sits in this band:

• CJC-1295 (no DAC): roughly 100 to 300 mcg per dose in reference material
• Ipamorelin: roughly 100 to 300 mcg per dose in reference material
• Common pairing: many blends are sold and discussed at a 1:1 ratio, so a 200 to 300 mcg figure is often applied to each component

A frequent reference point is 200 to 300 mcg of each, once or twice daily, with timing often noted around sleep or post-activity in the literature. These are descriptions of what sources report, not a recommendation to dose.

The 1 unit = 0.02 mg rule

Insulin syringes are marked in units, not milligrams. A U-100 syringe has 100 units per 1 mL. The unit value of a dose depends entirely on the vial concentration, so the "1 unit = 0.02 mg" figure is only true at one specific concentration. Here is where it comes from.

Take a common setup: a 5 mg blend vial reconstituted with 2.5 mL of bacteriostatic water.

1. Concentration = 5 mg / 2.5 mL = 2 mg per mL
2. Per unit = 2 mg / 100 units = 0.02 mg per unit (which is 20 mcg per unit)
3. A 200 mcg dose = 200 / 20 = 10 units
4. A 300 mcg dose = 300 / 20 = 15 units

That is the origin of the rule: at 2 mg/mL, every syringe unit carries 0.02 mg. Change the water volume and the rule changes with it. Reconstitute the same 5 mg vial with 1.25 mL instead and you get 4 mg/mL, so each unit is 0.04 mg and a 200 mcg dose is only 5 units. The mg to units calculator converts any concentration, and the reconstitution calculator solves the water side first.

Mixing the blend in one vial

Blends arrive two ways: a single vial with both peptides already combined, or two separate vials. For a pre-combined vial, you reconstitute once and the unit math above applies to the total. For separate vials, each is reconstituted on its own and the question of combining them in one syringe is a handling topic covered in can you mix two peptides in one syringe.

General lab-handling reference points that show up across sources:

• Add bacteriostatic water slowly down the vial wall, not directly onto the powder
• Swirl gently, do not shake, and let the powder dissolve on its own
• Pick a water volume that lands your dose on a clean unit mark, which makes drawing repeatable

For the full procedure see how to reconstitute peptides and the volume side in how much bacteriostatic water to add.

Cycle length as commonly described

Growth-hormone-secretagogue protocols in reference material are usually framed in cycles rather than open-ended use, often noted around 8 to 12 weeks followed by a break. The stated reasoning in sources is receptor sensitivity over time. General cycle framing is covered in how long to cycle peptides. These are descriptions of reported practice, not instructions, and timing decisions belong with a clinician.

Worked example end to end

A 5 mg blend vial, 2.5 mL of water, targeting a 250 mcg reference dose:

• Concentration: 5 mg / 2.5 mL = 2 mg/mL = 20 mcg per unit
• Dose in units: 250 mcg / 20 = 12.5 units
• Doses per vial: 5000 mcg / 250 = 20 doses
