GHRP-2 + CJC-1295 stack calculator

GHRP-2 paired with CJC-1295 without DAC is another common GHRP + GHRH growth stack. Both are dosed in micrograms but reconstitute to their own concentrations, so calculate each separately below.

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.

GHRP-2 reference

U-100 units to draw for each common GHRP-2 dose, by vial size, reconstituted with 2 mL of bacteriostatic water.

How GHRP-2 and CJC-1295 pair

GHRP-2 (a GHRP) and CJC-1295 (a GHRH) act on different pathways for a larger combined GH response, so they are typically dosed at the same time. With two separate vials, each has its own concentration — calculate both, then combine the schedule only.

  • Separate vials = separate concentrations and draws
  • Dosed together for a combined GH pulse
  • Both are small mcg draws — a U-100 syringe helps

Keeping two small draws straight

Both compounds are dosed in the low hundreds of micrograms, so the two draws are small and easy to confuse. The per-compound reference tables above show each at its own concentration; keep them labelled separately and confirm each unit count before drawing.

  • Both dosed in mcg — draws are small
  • Label each vial and confirm units separately
  • More BAC water spreads a small dose across more units

Frequently asked questions

Can GHRP-2 and CJC-1295 go in one syringe?
Calculate each compound's volume separately first, since the two vials have different concentrations. Combining the two solutions afterward is a handling choice, not a math shortcut.
Is GHRP-2 + CJC-1295 better than ipamorelin + CJC-1295?
This page does not rank protocols. GHRP-2 has a stronger GH response with more appetite effect than ipamorelin; the reconstitution math is identical, so the choice is about effect, not calculation.
What schedule is common for this stack?
GHRP + GHRH pairs are frequently dosed together one or more times daily. This page provides the reconstitution math only; follow the schedule your protocol or clinician specifies.
