how to mix cjc-1295: Frequently asked questions

Recalculate syringe units using the same formula with your new target dose. If you initially dosed 100mcg of each peptide (4 units from a 2,500mcg/mL solution) and want to increase to 150mcg, the new dose is (150mcg / 2,500mcg/mL) × 100 = 6 units. Each 1-unit change on your syringe represents a 25mcg dose change when concentration is 2,500mcg/mL. This allows fine-tuning in 25mcg increments without reconstituting a new vial. Higher concentrations (e.g., 5,000mcg/mL from 1mL reconstitution) make 1-unit syringe changes equal 50mcg dose shifts, reducing adjustment precision.

Your concentration is now lower than calculated, meaning you need more syringe units per dose to hit your target. Recalculate using the actual volume you added. If you intended 2mL but added 3mL to a 5mg + 5mg vial, concentration drops from 2,500mcg/mL to 1,667mcg/mL. A 100mcg dose now requires (100 / 1,667) × 100 = 6 units instead of 4. The solution remains usable. Just adjust your dosing volume. Do not attempt to 'concentrate' the solution by removing liquid after reconstitution. You'll remove peptide along with the water.
