Key Takeaway
Step-by-step guide to reconstituting CJC-1295/Ipamorelin. Bacteriostatic water ratios, mixing technique, and common mistakes to avoid.
Quick Answer: CJC-1295/Ipamorelin how to reconstitute requires adding bacteriostatic water (BAC water) to the lyophilized (freeze-dried) peptide powder. The standard approach is to add 2 mL of BAC water to a typical 5 mg vial, then gently swirl until dissolved. Never shake the vial. The entire process takes about 2 minutes and requires only a syringe, BAC water, and alcohol swabs. Your prescribing pharmacy should provide specific reconstitution instructions for your exact product .
What You Need
- Lyophilized CJC-1295/Ipamorelin vial: The freeze-dried powder (typically a small white cake or powder at the bottom of the vial)
- Bacteriostatic water (BAC water): Sterile water containing 0.9% benzyl alcohol as a preservative. This allows multi-dose use over days to weeks
- Syringe with needle: A 1 mL or 3 mL syringe with an 18-21 gauge needle for drawing BAC water (a larger gauge makes drawing easier)
- Alcohol swabs: For sterilizing vial tops before piercing
- Insulin syringes: 29-31 gauge, 0.5 mL or 1 mL for your actual injections after reconstitution
Important: Don't use sterile water (without the bacteriostatic agent) unless you plan to use the entire vial in a single dose. Sterile water lacks the preservative needed for multi-dose vials.
Step-by-Step Reconstitution
Step 1[1]: Prepare Your Workspace
Wash your hands thoroughly. Work on a clean, flat surface. Gather all supplies before starting.

| Ipamorelin | 75 | Anti-aging and recovery |
| GHK-Cu | 70 | Skin and tissue repair |
Step 2[2]: Clean Vial Tops
Swab the top of both the peptide vial and the BAC water vial with alcohol wipes. Allow to air dry for 10 seconds.
Step 3[3]: Draw Bacteriostatic Water
Using a 1-3 mL syringe with an 18-21 gauge needle, draw 2 mL of BAC water (or the amount specified by your pharmacy). Pull back the plunger first to fill the syringe with air equal to the volume you want to draw, then insert the needle into the BAC water vial and push the air in (this creates positive pressure making drawing easier), then invert and draw the water.
Step 4[4]: Add Water to the Peptide Vial
Insert the needle into the peptide vial at an angle, aiming the stream of water along the inside wall of the vial, not directly onto the powder. Release the water slowly and gently. Let gravity do the work. The water should trickle down the glass wall onto the powder.
Step 5[5]: Mix Gently
Do NOT shake the vial. Peptides are fragile molecules and aggressive shaking can damage their structure. Instead:
- Gently roll the vial between your palms for 30 seconds
- Let it sit for 1 to 2 minutes
- If powder remains undissolved, gently swirl the vial in small circles
- The solution should be clear and colorless when fully dissolved
Step 6: Inspect the Solution
The reconstituted solution should be completely clear with no visible particles, cloudiness, or discoloration. If the solution is cloudy, contains particles, or is discolored, don't use it. Contact your pharmacy.
Step 7: Store Properly
Place the reconstituted vial in the refrigerator (36-46 degrees F / 2-8 degrees C). Don't freeze reconstituted peptides. See our CJC-1295/Ipamorelin storage instructions guide for detailed storage information.
Calculating Your Dose
Once reconstituted, you need to calculate how many units on your insulin syringe equal your prescribed dose. The formula is:

| Prescribed Dose | Volume to Inject | Insulin Syringe Units |
|---|---|---|
| 100 mcg | 0.04 mL | 4 units |
| 200 mcg | 0.08 mL | 8 units |
| 250 mcg | 0.10 mL | 10 units |
| 300 mcg | 0.12 mL | 12 units |
| 500 mcg | 0.20 mL | 20 units |
Note: 1 mL = 100 units on a standard insulin syringe (U-100).
Common Mistakes to Avoid
- Shaking the vial: This is the most common mistake. Shaking creates foam and can denature the peptide, reducing potency
- Spraying water directly on the powder: Aim the stream along the glass wall, not onto the powder cake
- Using sterile water instead of BAC water: Sterile water lacks preservative and must be used in a single session
- Using too little or too much water: Follow your pharmacy's instructions. Using less water means more concentrated doses (smaller injection volumes) but shorter shelf life
- Room temperature reconstitution: Both vials should be at room temperature before mixing to ensure proper dissolution
Frequently Asked Questions
How long does reconstituted CJC-1295/Ipamorelin last?
When mixed with bacteriostatic water and stored in the refrigerator, reconstituted CJC-1295/Ipamorelin typically remains stable for 4 to 6 weeks. Some pharmacies recommend using within 28 days for maximum potency. Never use a vial that has been reconstituted for more than 6 weeks.
Can I use regular water instead of bacteriostatic water?
No. Regular tap water isn't sterile and will contaminate the vial. Even sterile water (without benzyl alcohol) should only be used for single-dose preparations. Bacteriostatic water is required for multi-dose vials.
What if I see particles after reconstitution?
Small particles that dissolve within a few minutes of gentle swirling are normal. If particles persist after 5 minutes of gentle mixing, or if the solution is cloudy, don't use it. Contact your pharmacy for a replacement.
Does my pharmacy provide reconstituted peptides?
Some compounding pharmacies ship pre-reconstituted peptides. At FormBlends, we can help you find the most convenient option for your situation.
