Use this free calculator to reconstitute CJC-1295 for research: enter the milligrams in your vial and the millilitres of bacteriostatic water, and it returns the concentration in mg/mL, the volume to draw for any target, and the U-100 unit equivalent. The reference data and concentration matrix below are specific to CJC-1295 and can be checked by hand or cited.
CJC-1295 reference data
| Class | Long-acting GHRH analog (modified GRF 1-29 with DAC / maleimidopropionyl albumin-binding linker) |
|---|---|
| Molecular formula | C165H269N47O46 |
| Molecular weight | 3647.2 g/mol (DAC form; non-DAC ~3368 — see notes) |
| CAS | 446262-90-4 |
| PubChem CID | 91971820 |
| Typical vial sizes | 2 mg / 5 mg |
| Storage | Lyophilized: -20 C sealed and desiccated, out of light. Reconstituted: 2-8 C, protect from light; typical ~4-week refrigerated working window. |
Molecular weight and nmol/mL are for the DAC form (CID 91971820). The non-DAC “mod GRF 1-29” variant is a different molecule (~3368 g/mol); for it, multiply nmol/mL by ~1.08. Confirm which form your vial is before mass calculations.
Concentration matrix for CJC-1295
Each cell = concentration for that vial mass and diluent volume, with mcg per U-100 unit and nmol/mL (from MW 3647.2). Concentration = vial mg ÷ water mL.
| Vial ↓ / Water → | 1 mL | 2 mL | 3 mL | 5 mL |
|---|---|---|---|---|
| 2 mg | 2.00 mg/mL 20.0 mcg/unit · 548 nmol/mL |
1.00 mg/mL 10.0 mcg/unit · 274 nmol/mL |
0.67 mg/mL 6.7 mcg/unit · 183 nmol/mL |
0.40 mg/mL 4.0 mcg/unit · 110 nmol/mL |
| 5 mg | 5.00 mg/mL 50.0 mcg/unit · 1371 nmol/mL |
2.50 mg/mL 25.0 mcg/unit · 685 nmol/mL |
1.67 mg/mL 16.7 mcg/unit · 457 nmol/mL |
1.00 mg/mL 10.0 mcg/unit · 274 nmol/mL |
Handling & notes
Water-soluble; PubChem CID 91971820 corresponds to the DAC (drug-affinity-complex) form bearing a maleimidopropionyl linker. The non-DAC modified GRF 1-29 variant is a different molecule (approx. C152H252N44O42, ~3368 g/mol) - confirm which form a given vial contains before mass calculations.
