Quick Answer
Because the CJC-1295 No DAC / Ipamorelin Blend is co-lyophilized, both compounds dissolve together in a single reconstitution step, and the resulting solution carries equal mg/mL concentrations of each peptide (since the vial contains equal masses of both at a 1:1 ratio). Reconstituting a 5mg/5mg vial with 2mL of bacteriostatic water yields 2.5mg/mL of CJC-1295 No DAC and 2.5mg/mL of Ipamorelin simultaneously in the same draw. This guide walks through the concentration math, dosing tables, and syringe draw volumes for both the 5mg/5mg and 10mg/10mg vials.

Why the Math Differs From a Single-Compound Peptide
When reconstituting a single peptide, the concentration calculation is simple: total mg of peptide divided by mL of bacteriostatic water added equals mg/mL. The co-lyophilized blend uses the same underlying math, but researchers need to remember that the resulting concentration applies to each compound independently, not to a combined total.
Because the blend is manufactured at a fixed 1:1 ratio by weight, the concentration of CJC-1295 No DAC and the concentration of Ipamorelin in the reconstituted solution will always be identical to each other, regardless of how much bacteriostatic water is added. Adding more water lowers both concentrations proportionally; it does not change the ratio between them.
Step-by-Step Reconstitution
- Check the COA fill weight. Confirm the labeled amount (5mg/5mg or 10mg/10mg) against the batch-specific Certificate of Analysis before calculating concentration.
- Select a bacteriostatic water volume based on the target concentration and your syringe's smallest reliable increment (see the dosing tables below for common choices).
- Wipe the vial stopper with an alcohol swab before puncturing.
- Insert the needle at an angle and direct the water stream against the interior glass wall of the vial, not directly onto the lyophilized cake, to prevent foaming.
- Swirl gently until fully dissolved. Do not shake or vortex — mechanical agitation can cause peptide aggregation.
- Inspect the solution. It should be clear and colorless. Any cloudiness, particulates, or discoloration means the vial should not be used.
- Label the vial with the reconstitution date and resulting concentration for both compounds.
Dosing Table: 5mg/5mg Vial
The 5mg/5mg vial contains 5mg of CJC-1295 No DAC and 5mg of Ipamorelin (10mg total peptide mass).
| Bacteriostatic Water Added | CJC-1295 No DAC Concentration | Ipamorelin Concentration | Volume for 100mcg/100mcg Dose | Insulin Syringe Units (100 IU/mL) |
|---|---|---|---|---|
| 1mL | 5mg/mL | 5mg/mL | 0.02mL | 2 units |
| 2mL | 2.5mg/mL | 2.5mg/mL | 0.04mL | 4 units |
| 3mL | 1.67mg/mL | 1.67mg/mL | 0.06mL | 6 units |
Dosing Table: 10mg/10mg Vial
The 10mg/10mg vial contains 10mg of CJC-1295 No DAC and 10mg of Ipamorelin (20mg total peptide mass).
| Bacteriostatic Water Added | CJC-1295 No DAC Concentration | Ipamorelin Concentration | Volume for 100mcg/100mcg Dose | Insulin Syringe Units (100 IU/mL) |
|---|---|---|---|---|
| 2mL | 5mg/mL | 5mg/mL | 0.02mL | 2 units |
| 3mL | 3.33mg/mL | 3.33mg/mL | 0.03mL | 3 units |
| 4mL | 2.5mg/mL | 2.5mg/mL | 0.04mL | 4 units |
These reference points assume a target dose of 100mcg/100mcg per administration, a commonly cited starting point in the published GH secretagogue research literature for this combination. Actual dosing should always follow the specific research protocol and institutional guidelines governing the study.
Choosing a Bacteriostatic Water Volume
Because the blend delivers both compounds at the same concentration from a single reconstitution, the water volume decision is simpler than for a two-vial protocol — there is only one number to choose, not two. The main trade-off is between draw precision and total usable doses per vial:
- Smaller water volumes (e.g., 1mL for the 5mg/5mg vial) produce higher concentrations, meaning smaller draw volumes per dose. This is useful when a protocol calls for very small per-administration amounts and a researcher wants the draw to stay comfortably above the syringe's minimum reliable increment, but it also means each dose consumes a larger fraction of the vial, yielding fewer total administrations before the vial is exhausted.
- Larger water volumes (e.g., 3mL for the 5mg/5mg vial) produce lower concentrations and larger draw volumes per dose, which can make each individual draw easier to measure accurately on a coarse-increment syringe, at the cost of a larger reconstituted-solution footprint to store and a slightly more dilute solution overall.
A useful check before finalizing a volume: divide the total mg of each compound in the vial by the target per-dose amount to estimate how many administrations the vial will support at a given concentration, then confirm the resulting draw volume is comfortably readable on the syringe being used. For side-by-side automated calculations across a range of target doses, see the CJC-1295 Reconstitution Calculator and Ipamorelin Reconstitution Calculator — while these tools are built for single-compound vials, the same concentration math applies to each compound within the blend individually, since both dissolve at equal mg/mL regardless of water volume chosen.
Syringe Draw Reference
Standard insulin syringes are marked in units, where 100 units equals 1mL (for a 100 IU/mL syringe). This is convenient for the blend because both compounds are drawn simultaneously in a single volume — there is no need to calculate and draw two separate syringe volumes as there would be with two separately reconstituted vials.
Example: with a 2mL reconstitution of the 5mg/5mg vial (2.5mg/mL each compound), drawing 4 units (0.04mL) delivers 100mcg of CJC-1295 No DAC and 100mcg of Ipamorelin in a single draw.
Common Reconstitution Mistakes
- Assuming the labeled dose is a combined total. A 5mg/5mg vial is 5mg of each compound, not 5mg combined — see the pillar guide's dosing section for the full breakdown.
- Vortexing or shaking the vial instead of gently swirling, which can denature or aggregate the peptides.
- Injecting bacteriostatic water directly onto the lyophilized cake rather than against the vial wall, causing foaming that can trap air and make visual inspection difficult.
- Skipping the COA fill-weight check and assuming the label amount exactly matches the measured fill in every vial.
- Reusing bacteriostatic water past 28 days once its own container has been opened, independent of the peptide vial's reconstituted shelf life.
Most of these mistakes carry over directly from single-compound peptide handling, but the co-lyophilized format raises the stakes slightly: because both compounds share one vial, any reconstitution error (foaming, aggregation, contamination) affects both peptides simultaneously rather than isolating the problem to a single vial. This is one reason the visual inspection step should never be skipped — a compromised co-lyophilized vial cannot be partially salvaged the way a single-compound vial sometimes can.
Multi-Dose Vial Usage Across the Reconstituted Window
A single reconstituted vial is typically used across multiple administrations over its 14-to-28-day stability window, not drawn down in one session. Tracking usage accurately over that window matters more with the blend than with a single-compound vial, since a labeling or logging error affects the dosing record for both compounds at once. Best practices for multi-dose tracking include:
- Labeling the vial immediately after reconstitution with the date and the calculated mg/mL concentration for both compounds
- Logging each draw (date, volume, calculated dose) in a research notebook or LIMS entry tied to the vial's unique lot/batch identifier from the COA
- Re-inspecting the solution visually before every draw, not just at the time of reconstitution, since particulate formation or discoloration can develop over the storage window
- Discarding any remaining volume once the vial reaches the end of its stability window, even if visually clear, since research-grade bacteriostatic solutions are not validated for extended use beyond the standard 14-to-28-day range
Storage After Reconstitution
- Store the reconstituted solution at 2 to 8°C (standard refrigeration)
- Use within 14 to 28 days of reconstitution with bacteriostatic water
- Avoid repeated freeze-thaw cycles
- Keep the vial protected from light
- Discard immediately if the solution becomes cloudy or shows particulate matter
These storage parameters exist to preserve peptide integrity, not merely as generic handling advice. Refrigeration slows the hydrolysis and oxidation reactions that gradually degrade peptide bonds in solution, while avoiding freeze-thaw cycles prevents the mechanical stress on peptide structure that repeated ice-crystal formation can introduce. Light exposure similarly accelerates degradation for both CJC-1295 No DAC and Ipamorelin, which is why opaque or amber vial storage (or simply keeping the vial in its original box inside the refrigerator) is standard practice across co-lyophilized and single-compound peptides alike.
Frequently Asked Questions
Do I need to reconstitute the two compounds separately since they're different molecules?
No. Because the blend is co-lyophilized, both compounds are already combined in the same lyophilized cake and dissolve together with a single addition of bacteriostatic water. There is no separate reconstitution step for each compound.
Will the CJC-1295 No DAC and Ipamorelin concentrations always be equal after reconstitution?
Yes. Since the vial is manufactured with equal masses of each compound (1:1 ratio), any volume of bacteriostatic water added will produce equal mg/mL concentrations of both compounds in the resulting solution.
What bacteriostatic water volume should I use?
This depends on your target dose and syringe precision. The dosing tables above show common reference points for both vial sizes. Smaller water volumes produce higher concentrations (useful for smaller draw volumes on a fine-increment syringe); larger volumes produce lower concentrations and larger draw volumes, which can improve dosing precision on syringes with coarser markings.
How long does the reconstituted blend remain stable?
When reconstituted with bacteriostatic water and stored at 2 to 8°C, the solution is typically usable for 14 to 28 days, consistent with standard lyophilized peptide handling guidance.
Can I use plain sterile water instead of bacteriostatic water?
Sterile water lacks the benzyl alcohol preservative in bacteriostatic water, so it does not inhibit microbial growth across repeated vial punctures. It is only appropriate for single-session, same-day use, not for a multi-dose reconstituted vial intended to last 14 to 28 days.
Does the co-lyophilized format change the reconstituted stability window compared to a single peptide?
No. The 14-to-28-day stability window with refrigerated storage applies the same way to the blend as it does to CJC-1295 No DAC or Ipamorelin reconstituted individually. Co-lyophilization affects how the two compounds are combined at the manufacturing stage, not the post-reconstitution handling or shelf-life guidance, which follows standard lyophilized peptide practice.
What happens if I add too much or too little bacteriostatic water by mistake?
The resulting concentration will simply be higher or lower than intended for both compounds equally, since the ratio between them stays fixed regardless of water volume. Recalculate the actual mg/mL for both compounds based on the volume that was actually added, and adjust the draw volume for each dose accordingly rather than assuming the originally planned draw volume is still correct.
Do I need different syringes for the blend compared to a single-compound peptide?
No. Standard insulin syringes in the 0.3mL to 1mL range, marked in units for a 100 IU/mL concentration, work the same way for the blend as for any single-compound reconstituted peptide. The only difference is that a single draw from the blend delivers two compounds instead of one, since both are present at equal concentration in the same solution.
