Ipamorelin + CJC-1295 stack calculator

Pairing a GHRP (ipamorelin) with a GHRH (CJC-1295) is the classic growth-hormone stack. If your vial is a pre-blend, use the CJC-1295 / Ipamorelin blend calculator; if you have two separate vials, calculate each below and combine only the schedule.

Per-compound reconstitution

Each compound is calculated on its own — different vials, different concentrations, different draws. Use these references, then run your exact numbers on each compound's calculator.

Ipamorelin reference

U100 units to draw for each common Ipamorelin dose, by vial size, reconstituted with 2.5 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.

VialConcentration100 mcg200 mcg300 mcg
2 mg0.8 mg/mL12.5 u(0.13 mL)25 u(0.25 mL)37.5 u(0.38 mL)
5 mg2 mg/mL5 u(0.05 mL)10 u(0.1 mL)15 u(0.15 mL)

Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.

CJC-1295 (no DAC) reference

U100 units to draw for each common CJC-1295 (no DAC) dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.

How the GHRP and GHRH pair

Ipamorelin (a GHRP) and CJC-1295 without DAC (a GHRH) are typically dosed together because they act on different pathways for a larger combined GH pulse. With two separate vials, each has its own concentration and draw — calculate them independently, then dose at the same time.

  • Separate vials = separate concentrations and draws
  • Often dosed together for a combined GH pulse
  • If pre-blended, use the CJC-1295 / Ipamorelin calculator instead

Two vials or one blend?

Some sources sell ipamorelin and CJC-1295 pre-mixed in a single vial labelled with a combined total; others sell them separately. This page is for two separate vials. If yours is a single blended vial, work from its labelled total on the blend calculator so the math matches the label.

  • Two vials: calculate each here
  • One blended vial: use the blend calculator's combined total
  • Confirm the labelled ratio before interpreting component amounts

Frequently asked questions

Should ipamorelin and CJC-1295 be drawn together?+
Calculate each compound's volume separately first, because two vials have different concentrations. Whether you then combine the two solutions in one syringe is a handling choice, not a math shortcut.
Is this the same as the CJC-1295 / Ipamorelin blend?+
Only if your vial is pre-blended. A blended vial lists a combined milligram total and uses the blend calculator; two separate vials are each calculated on their own page.
What's a common ipamorelin + CJC-1295 schedule?+
They are frequently dosed together one or more times a day. This page does not recommend a protocol — it provides the reconstitution math so your prescribed schedule is easy to draw.
