GH stack Calculator
The "GH stack" is a term used in online peptide communities to refer to a combination that includes CJC-1295 (no DAC) and Ipamorelin. This page provides dosage and reconstitution calculators for each peptide commonly referenced in this stack. Nothing on this page constitutes medical advice or a recommendation. Research peptides are not FDA-approved for human consumption and are labeled for research use only.

GH stack dosage charts
Below is one dosage chart per component peptide. Each chart shows how the reconstitution math works across a range of sample dose levels. These are mathematical examples only, not recommendations.
CJC-1295 (no DAC)
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 88 mcg | 1 mg/mL | 0.088 mL | 8.8 |
| 180 mcg | 1 mg/mL | 0.18 mL | 18 |
| 350 mcg | 1 mg/mL | 0.35 mL | 35 |
| 700 mcg | 1 mg/mL | 0.7 mL | 70 |
| 1400 mcg | 1 mg/mL | 1.4 mL | 140 |
For your own target dose, use the CJC-1295 (no DAC) calculator.
Ipamorelin
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 130 mcg | 2.5 mg/mL | 0.052 mL | 5.2 |
| 250 mcg | 2.5 mg/mL | 0.1 mL | 10 |
| 500 mcg | 2.5 mg/mL | 0.2 mL | 20 |
| 1000 mcg | 2.5 mg/mL | 0.4 mL | 40 |
| 2000 mcg | 2.5 mg/mL | 0.8 mL | 80 |
For your own target dose, use the Ipamorelin calculator.
How to reconstitute GH stack peptides
Each peptide in the GH stack follows the same reconstitution process: draw bacteriostatic water into a syringe, inject it slowly down the side of the peptide vial, swirl gently (do not shake), and store refrigerated. For peptide-specific notes on vial sizes and typical reconstitution volumes, see each component's page:
