Reconstitution setup for CJC-1295 and ipamorelin showing vials, bacteriostatic water, and insulin syringe

Two vials of powder, a bottle of bacteriostatic water, and no instructions anywhere on the box. Here is the answer: add 2 mL of bacteriostatic water to each 5 mg vial (or to a 5 mg/5 mg blend vial), aim the stream at the glass wall, swirl gently, and refrigerate at 2 to 8 degrees C. At that ratio, every unit on a U-100 insulin syringe holds 25 mcg of peptide.

One label warning before anything else: a "10 mg blend" vial is 5 mg of CJC-1295 plus 5 mg of ipamorelin, never 10 mg of each. This page covers mixing and drawing only; for how much to take, use the CJC-1295 dosage guide, and check every ratio with the peptide reconstitution calculator.

Separate Vials or a Pre-Mixed Blend? Know What You Are Holding

The combo ships in two formats. Separate vials give you CJC-1295 (2 or 5 mg, with DAC or without) and ipamorelin (2, 5, or 10 mg) as individual powders. Blend vials arrive co-lyophilized, usually 5 mg of each in one vial.

A blend means one reconstitution, one draw, and a fixed 1:1 ratio. Separate vials mean two reconstitutions, but you control each peptide's concentration and can run ratios other than 1:1. Neither format changes the technique below.

DAC and no-DAC CJC-1295 reconstitute identically: same water, same math per milligram. Which version you should be holding is a dosing question, answered in the DAC vs no-DAC comparison.

Step-by-Step Reconstitution

The procedure is identical for every vial. With separate vials, run it twice, once per powder.

  1. 1.Warm up. Let the vials reach room temperature. Wash your hands and clear a clean surface.
  2. 2.Swab. Wipe the rubber stopper of the peptide vial and the bacteriostatic water vial with separate alcohol wipes. Let both dry fully.
  3. 3.Draw the water. Pull the target volume into a syringe. 2 mL is 200 units on a U-100 insulin syringe; a 3 mL syringe makes this one draw.
  4. 4.Aim at the glass. Insert the needle at an angle and run the stream down the inside wall of the vial. Jetting water straight onto the powder churns it into foam.
  5. 5.Swirl, never shake. Roll the vial gently until the solution clears. Mechanical agitation drives peptides to aggregate in solution (Manning et al., Pharm Res, 2010, PMID 20143256), and aggregated peptide is wasted peptide.
  6. 6.Inspect. The solution must be clear and colorless. Cloudiness, floating particles, or any color means the vial does not get injected.
  7. 7.Label. Write the date and the concentration in mcg per unit on the vial. That label is the single cheapest protection against the double-dose mistake below.
  8. 8.Refrigerate. 2 to 8 degrees C (36 to 46 degrees F), upright, away from light.

The full generic technique, including how to handle stubborn powder, lives in the peptide reconstitution walkthrough.

Drawing the Dose: Two Vials, One Syringe

With separate vials, you do not need two injections. Draw the CJC-1295 dose into your insulin syringe first, then push the same needle into the ipamorelin vial and draw that dose on top. The peptides share the syringe for seconds on their way into the same subcutaneous site, which is standard practice and not a stability concern.

Worked example at 5 mg/2 mL for both peptides: 100 mcg of CJC-1295 is 4 units, 100 mcg of ipamorelin is 4 more units, so the syringe reads 8 units total. Where the needle goes afterward is covered in the injection site guide.

What you should not do is build a DIY blend for storage by transferring one reconstituted peptide into the other's vial. Commercial blends are co-lyophilized under manufacturing control; no published data covers home-mixed solutions sitting in a fridge for weeks. Mix in the syringe, not in the vial.

The dose numbers themselves come from your protocol, not from this page. Pick them in the CJC-1295 dosage guide or the solo ipamorelin dosage guide.

Unit Math: What to Draw for 100, 200, and 300 mcg

One formula runs every table on this page: units = dose in mcg divided by (mg in vial times 10, divided by mL of water). A U-100 syringe holds 100 units per mL, so 1 unit is 0.01 mL.

Setupmcg per unit100 mcg200 mcg300 mcg

2 mg vial + 1 mL205 units10 units15 units
2 mg vial + 2 mL1010 units20 units30 units
10 mg vial + 2 mL502 units4 units6 units
Blend 5/5 + 2 mL25 each4 units8 units12 units

On the blend rows, one draw carries both peptides: 4 units of a 5/5 blend at 2 mL delivers 100 mcg of CJC-1295 and 100 mcg of ipamorelin together.

Run your own numbers through the peptide reconstitution calculator before the first draw, and keep the CJC-1295/ipamorelin dosage calculator bookmarked for protocol changes.

What Goes Wrong: Three Quantified Mistakes

Half the water, double the dose. You planned 2 mL into a 5 mg vial for 25 mcg per unit, but only 1 mL went in. The vial now holds 50 mcg per unit. Your usual 4-unit draw delivers 200 mcg instead of 100 mcg, a silent 2x overdose repeated every night until the vial empties. Fix: read the syringe barrel before injecting the water, and write the real concentration on the label.

Reading "10 mg blend" as 10 mg of each. The label means 5 mg of CJC-1295 plus 5 mg of ipamorelin. Compute from 10 mg per peptide and every draw lands at half your intended dose, or double it if you "correct" in the wrong direction. Fix: blends state total peptide mass; divide by two before doing any math.

Sterile water on a multi-week vial. Bacteriostatic water carries 0.9% benzyl alcohol, the preservative that suppresses microbial growth across repeated needle punctures of a multi-dose vial (Meyer et al., J Pharm Sci, 2007, PMID 17722087). Plain sterile water has none, and a CJC/ipamorelin vial gets punctured nightly for 3 to 6 weeks. Every puncture becomes a contamination opportunity with nothing pushing back. Fix: bacteriostatic water for any vial that outlives one use; the reconstitution solution comparison sorts the labels.

Storage After Mixing

Unmixed powder is forgiving: refrigerated and dark, it keeps for months. Reconstituted solution is on a clock from the moment water touches powder. Peptides in solution degrade progressively through hydrolysis, oxidation, and aggregation (Manning et al., Pharm Res, 2010, PMID 20143256).

The practical window with bacteriostatic water is 4 to 6 weeks at 2 to 8 degrees C, with best potency inside about 30 days. Those durations are standard practice, not peptide-specific trial data; treat them as the conservative call. Blend vials follow the same clock. Full timelines by peptide are in the reconstituted shelf-life guide, and the water itself has its own expiry, covered in the bacteriostatic water shelf-life guide.

Never freeze a reconstituted vial, never leave it on the counter overnight, and discard it the day it turns cloudy. A quick recap of the remaining traps: shaking instead of swirling, skipping the stopper swab, skipping the label, doing U-100 math on a U-40 or tuberculin syringe, and topping up a nearly empty vial with fresh water to stretch the last doses.

Frequently Asked Questions

Can you mix CJC-1295 and ipamorelin in the same syringe?

Yes. Draw the CJC-1295 dose first, then the ipamorelin dose into the same U-100 syringe, and inject once. The peptides share the syringe for seconds, which poses no stability problem. Site choice is covered in the injection site guide.

Can you reconstitute CJC-1295 and ipamorelin in the same vial?

Not for storage. No published stability data covers home-mixed peptide solutions kept for weeks. Use a commercial co-lyophilized blend, or keep two vials and combine doses in the syringe, per the reconstitution walkthrough.

How much bacteriostatic water for a 5 mg/5 mg blend?

2 mL is the standard volume. That yields 2,500 mcg/mL of each peptide, so every unit on a U-100 insulin syringe carries 25 mcg of CJC-1295 and 25 mcg of ipamorelin. Verify other volumes with the peptide reconstitution calculator.

How many units is 100 mcg of CJC-1295 or ipamorelin?

It depends entirely on your water volume. At 5 mg/2 mL, 100 mcg is 4 units; at 2 mg/1 mL, it is 5 units; at 10 mg/2 mL, it is 2 units. The formula and dose targets live in the CJC-1295 dosage guide.

How long does reconstituted CJC-1295/ipamorelin last in the fridge?

Plan on 4 to 6 weeks maximum at 2 to 8 degrees C with bacteriostatic water, with best potency inside 30 days. Discard cloudy or discolored solution immediately. Peptide-by-peptide timelines are in the reconstituted shelf-life guide.

Can I use sterile water instead of bacteriostatic water?

Only if the whole vial is used immediately. Sterile water has no preservative, and a multi-week vial punctured nightly needs the 0.9% benzyl alcohol in bacteriostatic water to suppress contamination. The solution comparison guide explains the labels.

Is a 10 mg blend vial 10 mg of each peptide?

No. A 10 mg blend is 5 mg of CJC-1295 plus 5 mg of ipamorelin. Blend labels state total peptide mass, so divide by two before any unit math, or your doses run off by 2x. Cross-check with the CJC-1295/ipamorelin dosage calculator.

Does CJC-1295 with DAC reconstitute differently from no-DAC?

No. Same water volumes, same swirl technique, same math per milligram. The DAC modification changes half-life and dosing frequency, not mixing. Which version fits your protocol is covered in the DAC vs no-DAC comparison.

The Bottom Line

2 mL of bacteriostatic water per 5 mg vial gives 25 mcg per unit. Aim at the glass, swirl, label, refrigerate, and the vial serves you accurately for a month.

The principle: concentration is something you create, not something printed on the box. The label you write is the only record of it.

Verify every setup with the peptide reconstitution calculator before the first draw, then set your protocol with the CJC-1295 dosage guide. CJC-1295 and ipamorelin are research compounds, not FDA-approved therapies; this content is educational, not medical advice.
