AOD-9604 reconstitution and dosage explained: how much bacteriostatic water to add, syringe units per vial, typical 250–500 mcg protocols, and storage.
AOD-9604 is reconstituted by adding bacteriostatic water to the lyophilized powder, usually 1 to 3 mL per vial, and the protocols most often cited call for 250 to 500 mcg injected subcutaneously once daily. A 5 mg vial mixed with 2 mL of diluent gives 2,500 mcg per mL, so a 300 mcg dose measures 12 units on a U-100 insulin syringe. No FDA-approved human dose exists for AOD-9604, so everything here describes research and community practice rather than medical guidance.
What AOD-9604 Is and Why Mixing Matters
AOD-9604 is a synthetic peptide fragment of human growth hormone, corresponding to amino acids 176–191. Because it is a peptide, it ships as a freeze-dried powder that must be dissolved in liquid before use.
How you mix the vial decides how accurately you can measure a dose. Get the concentration wrong and the same syringe reading can deliver double or half the intended amount.
AOD-9604 is a research chemical, not an approved medication. The FDA declined to approve it as an obesity drug in 2007, and it is banned in sport under WADA category S0.
How to Reconstitute AOD-9604 Step by Step
Most vials contain 2 mg or 5 mg of powder. Bacteriostatic water is the standard diluent because its benzyl alcohol content slows bacterial growth in a multi-use vial.
- Wipe the rubber stoppers on both the peptide vial and the diluent vial with an alcohol swab and let them dry.
- Draw your chosen volume of bacteriostatic water into a fresh syringe.
- Insert the needle and aim the stream at the glass wall instead of directly at the powder.
- Swirl the vial gently between your fingers. Do not shake it, since shaking can damage the peptide chain.
- Let the vial rest a few minutes, then confirm no clumps remain before drawing a dose.
If the Powder Will Not Fully Dissolve
AOD-9604 dissolves more slowly than many peptides, and at higher concentrations it can look cloudy or gel-like. If that happens, add another 0.5 to 1 mL of diluent, swirl again, and give it time at room temperature. A clear, particle-free solution is the goal.
The Reconstitution Math: Concentration and Syringe Units
Concentration equals the total peptide in the vial divided by the total volume of diluent added. The table below shows common setups and how many units a 300 mcg dose requires on a U-100 insulin syringe.
| Vial size | Diluent added | Concentration | 300 mcg dose |
|---|---|---|---|
| 5 mg | 1 mL | 5,000 mcg/mL | 6 units |
| 5 mg | 2 mL | 2,500 mcg/mL | 12 units |
| 5 mg | 3 mL | 1,667 mcg/mL | 18 units |
| 2 mg | 1 mL | 2,000 mcg/mL | 15 units |
| 2 mg | 2 mL | 1,000 mcg/mL | 30 units |
Because 300 mcg from a 5 mg vial is such a small draw, many people prefer 2 to 3 mL of diluent so the syringe marking is easier to read. This is exactly why the aod-9604 5mg dosage question comes up so often: the volume you draw changes dramatically with the amount of water you add.
AOD-9604 Dosage: Typical Research Protocols
There is no official human dosage. Published studies used a range of amounts, and community protocols generally land between 250 and 500 mcg per day.
| Protocol level | Daily amount | Frequency |
|---|---|---|
| Conservative starting point | 250 mcg | Once daily |
| Most commonly cited range | 300 mcg | Once daily |
| Upper community range | 500 mcg | Once daily, or split into two 250 mcg doses |
Whatever aod 9604 dosage protocol you read, the concentration of the vial matters more than the number on the label. Two people using the same 300 mcg target can draw very different volumes if they mixed their vials differently.
Timing and Frequency
AOD-9604 has a short half-life measured in minutes rather than hours. Most people therefore inject once daily, often in the morning or before a meal, and rotate injection sites to limit irritation.
Men, Women, and Beginners
There is no reliable evidence that men and women need different amounts. Community write-ups on aod 9604 dosage for men typically land in the same 250–500 mcg range used for women, and body weight scaling is not supported by formal dosing studies.
People new to peptides are usually advised to start at the low end and hold there for a couple of weeks. A reasonable aod 9604 peptide dosage for beginners stays at 250 mcg daily until the injection routine and any reactions are understood.
Some users combine AOD-9604 with other research compounds, but those pairings have not been tested for safety or effectiveness in humans and should be treated as experimental.
Storage and Stability After Reconstitution
- Keep lyophilized powder refrigerated or frozen, away from light.
- Refrigerate reconstituted peptide at 2–8 °C.
- Store the vial upright and out of direct sunlight.
- Plan to finish a mixed vial within roughly 2 to 4 weeks.
- Never freeze a vial after it has been reconstituted.
- Discard any solution that turns cloudy or shows visible particles.
Safety, Legality, and Side Effects
AOD-9604 is not FDA-approved for human use in the United States. It is sold legally only as a research chemical, and products marketed for human consumption operate in a gray area that regulators have repeatedly warned about.
Reported reactions in research settings include injection-site irritation, headache, nausea, and fatigue. Because AOD-9604 is a growth hormone fragment, hormone levels and blood sugar are worth monitoring in any supervised setting.
Stacking AOD-9604 with prescription weight-loss drugs adds uncertainty. The aod 9604 and tirzepatide together side effects that people search for are largely unknown, because no controlled trial has combined them.
Anyone using AOD-9604 should weigh the lack of long-term human data against any hoped-for benefit, and should consult a licensed healthcare professional before starting. Nothing here is medical advice.
Key Takeaways
- AOD-9604 is reconstituted with bacteriostatic water, typically 1 to 3 mL per vial.
- A 5 mg vial mixed with 2 mL of diluent yields 2,500 mcg/mL, or 12 units per 300 mcg dose.
- Commonly cited research amounts range from 250 to 500 mcg injected subcutaneously once daily.
- AOD-9604 is not FDA-approved for human use and is prohibited in sport.
Frequently Asked Questions
How much bacteriostatic water do I add to a 5 mg AOD-9604 vial?
Most people add 1 to 3 mL to a 5 mg vial. Adding 2 mL creates a concentration of 2,500 mcg per mL, so a 300 mcg dose measures 12 units on a U-100 insulin syringe. Using more diluent makes small doses easier to measure and reduces the chance of the peptide gelling.
What is a typical AOD-9604 dosage?
Research and community protocols most often cite 250 to 500 mcg injected subcutaneously once daily, with 300 mcg being the most common figure. No official human dose exists because the FDA has not approved AOD-9604 for human use. Starting at the low end of that range is the usual recommendation.
How long is reconstituted AOD-9604 good for?
Reconstituted AOD-9604 should be refrigerated at 2–8 °C and used within roughly 2 to 4 weeks. Keep the vial upright and protected from light, and never freeze it after mixing. Discard the solution if it turns cloudy or contains visible particles.
