CJC-1295 ipamorelin 5/5 reconstitution explained: how much bacteriostatic water to add, concentration math, and injection-unit charts for a 10 mg blend.
The shorthand "5/5" describes a single vial that holds 5 mg of CJC-1295 and 5 mg of ipamorelin, for 10 mg of lyophilized powder total. Reconstituting that vial means adding bacteriostatic water until the powder dissolves into a clear liquid you can measure with a U-100 insulin syringe. With the most common approach, 2 mL of water, the vial ends up at 2.5 mg/mL of each peptide, so a 100 mcg/100 mcg dose equals 4 units on the syringe.
What 5/5 Means on a CJC-1295/Ipamorelin Vial Label
Suppliers label these vials in a few different ways: 5/5, 5 mg + 5 mg, or 10 mg blend. All three describe the same thing, an equal amount of two peptides in one lyophilized cake.
Before mixing, it helps to answer a basic question: what is cjc-1295 ipamorelin, and why are the two peptides combined? CJC-1295 is a growth hormone-releasing hormone (GHRH) analog, while ipamorelin is a selective ghrelin-receptor agonist. They act on different receptors, which is why researchers often study them together rather than alone.
One source of confusion is the name itself. CJC-1295 can mean the DAC version (drug affinity complex, long half-life) or the no-DAC version, frequently called mod GRF 1-29. Most 5/5 blends use the no-DAC form unless the label states otherwise.
How to Reconstitute a 5/5 Vial Step by Step
The cjc-1295/ipamorelin reconstitution process is the same whether your vial holds 2 mg, 5 mg, or 10 mg of total powder. Only the math changes. Work on a clean surface and let everything reach room temperature first.
- Wipe the rubber stopper of the peptide vial and the bacteriostatic water vial with fresh alcohol swabs, then let both dry.
- Draw your chosen volume of bacteriostatic water into a new syringe with a large-gauge needle.
- Insert the needle through the stopper at an angle and aim the stream at the glass wall, not directly at the powder. A direct hit can damage the peptide.
- Remove the needle and swirl the vial gently between your fingers until the powder fully dissolves. Do not shake it.
- Let the solution sit for a minute or two. It should be clear and colorless. Cloudiness or floating particles mean the vial should not be used.
- Write the date and the concentration you created on the label, then refrigerate the vial.
Reconstitution Math: Water Volume and Concentration
More water makes each dose easier to measure precisely, but it also means a larger injection volume. Less water keeps the shot small, but tiny doses become hard to read on the syringe.
| Bacteriostatic water added | Concentration of each peptide | 100 mcg dose | 200 mcg dose |
|---|---|---|---|
| 1 mL | 5 mg/mL | 2 units | 4 units |
| 2 mL | 2.5 mg/mL | 4 units | 8 units |
| 2.5 mL | 2 mg/mL | 5 units | 10 units |
| 3 mL | 1.67 mg/mL | 6 units | 12 units |
| 5 mL | 1 mg/mL | 10 units | 20 units |
These figures assume the vial contains 5 mg of each peptide. If your vial is a different size, recalculate from the total milligrams on the label rather than reusing someone else's numbers.
Reading Doses on a U-100 Syringe
U-100 insulin syringes are marked in units, where 100 units equals 1 mL. That single fact explains why dilution decides everything: 100 mcg of each peptide is 4 units at 2 mL of water, but 10 units at 5 mL.
Reported cjc-1295 ipamorelin dosage ranges vary widely in online discussions, and much of that information comes from forum posts rather than controlled trials. Whatever numbers you encounter, they should match the syringe math above. If a posted protocol does not line up with your concentration, recalculate before drawing anything.
CJC-1295 vs Ipamorelin vs Tesamorelin
The cjc-1295 vs ipamorelin comparison comes down to mechanism. One is a GHRH analog that signals the pituitary directly, and the other is a ghrelin mimetic that amplifies the body's natural pulse.
| Compound | Class | Approx. half-life | FDA status | Notes |
|---|---|---|---|---|
| CJC-1295 with DAC | GHRH analog | 6-8 days | Not approved | Long-acting; sustained IGF-1 elevation reported in early studies |
| CJC-1295 without DAC | GHRH analog | About 30 minutes | Not approved | The form most often used in 5/5 blends |
| Ipamorelin | Ghrelin receptor agonist | About 2 hours | Not approved | Selective; minimal cortisol and prolactin effect in animal models |
| Tesamorelin | GHRH analog | About 30 minutes | Approved for HIV-related visceral fat | The only compound in this group with an approved human indication |
The cjc-1295 ipamorelin vs tesamorelin discussion usually centers on regulatory status rather than mechanism. Tesamorelin has an approved prescription indication in the United States, while the other two remain research chemicals. CJC-1295 and ipamorelin are not FDA-approved for human use in the United States.
Storage, Stability, and Handling
- Powder: store frozen and protected from light. Many suppliers recommend -20 degrees Celsius for long-term storage.
- After mixing: refrigerate at 2-8 degrees Celsius and keep the vial upright.
- Bacteriostatic water contains benzyl alcohol, which limits bacterial growth and generally extends usable life compared with plain sterile water.
- Do not freeze a reconstituted vial. Repeated freeze-thaw cycles degrade peptides.
- Discard any vial that turns cloudy, changes color, or shows visible particles.
Safety and Legal Considerations
Products sold for research purposes only are not manufactured under pharmaceutical GMP conditions, so purity and actual peptide content can vary between suppliers. A certificate of analysis is a starting point, not a guarantee.
Reported side effects of growth hormone-related peptides include injection-site irritation, fluid retention, joint aches, and changes in blood sugar. Anyone with a history of cancer, diabetes, or pituitary disease should speak with a healthcare professional before considering these compounds.
Self-directed research protocols are not the same as medical treatment. A physician or pharmacist can help you interpret lab documentation and review interactions with medications you already take.
Frequently Asked Questions
How much bacteriostatic water do I add to a 5 mg/5 mg CJC-1295 ipamorelin vial?
Most people add 2 mL of bacteriostatic water to a 10 mg blend vial, which creates a concentration of 2.5 mg/mL of each peptide. Adding 3 mL makes small doses easier to fine-tune, while 1 mL keeps injection volume low but makes accurate measurement harder. There is no single official dilution, so choose one and record it on the label.
How many units is 100 mcg of CJC-1295 ipamorelin on an insulin syringe?
It depends entirely on how much water you added. At 2 mL per 10 mg vial, 100 mcg of each peptide equals 4 units on a U-100 syringe; at 3 mL it equals 6 units, and at 5 mL it equals 10 units. Always recalculate from your own vial size and water volume rather than copying someone else's numbers.
Is CJC-1295 ipamorelin FDA-approved for human use?
No. CJC-1295 and ipamorelin are not FDA-approved for human use in the United States and are typically sold as research chemicals. Tesamorelin is the only GHRH-related compound in this group with an approved prescription indication, and it is used for visceral fat in HIV-associated lipodystrophy. Talk to a healthcare professional before using any unapproved peptide.
