AOD-9604 weeks-of-supply at common cadences

How long one 5 mg AOD-9604 vial covers at a 0.3 mg per dose, for three weekly cadences. Total doses per vial: 16.

Doses per week	Total doses per vial	Weeks of supply

Math weeks-of-supply assumes every dose draws cleanly. Stability typically caps a reconstituted vial at 4–6 weeks of refrigerated use regardless of how much liquid remains.

Worked example

How long one AOD-9604 vial lasts, the long version

Total doses in the vial: floor(5 ÷ 0.3) = 16. The floor matters — a partial dose at the bottom doesn't count.
Cadence: 7 doses per week for AOD-9604 at this example step.
Math weeks-of-supply: 16 ÷ 7 = 2.3 weeks of liquid in the vial.
Stability ceiling: most reconstituted peptides are typically used within 4–6 weeks of refrigerated storage. Whichever number is smaller is the one that binds your refill date.
Doubling the dose roughly halves both numbers — and titration usually closes the gap between "math weeks" and "stability weeks" without you noticing.

Scenarios people actually run into

Three things that come up logging AOD-9604

Math says one 5 mg AOD-9604 vial covers 2.3 weeks at 0.3 mg per dose. Stability typically caps a reconstituted vial at 4–6 weeks. Whichever number is smaller is the date on your refill calendar.
Titration up doubles the dose and halves the vial. A 12-week-on-paper vial becomes a 6-week vial the day you step up — order the next vial the same day you take the step.
Shipping windows are the silent third constraint. If your supplier runs 1–3 weeks, the refill order has to leave at least that long before "math weeks" or "stability weeks," whichever is binding.

AOD-9604 is a small, modified piece of human growth hormone (hGH) that people explore for its effects on fat metabolism. Unlike full-length growth hormone, it was developed specifically to target fat cells without affecting blood sugar or causing growth. Early studies, including a Phase 2b trial in obese adults, reported that it influenced fat loss, though research is still considered preliminary. This page covers what AOD-9604 is, how it’s thought to work, and the ways people track its use in the Peptide Pilot app.

Planning AOD-9604 vials in real life

AOD-9604 vial planning depends on cycle length more than dose step. A 5 mg vial at 300 mcg daily covers 16 doses (about 2.5 weeks). A 4-week protocol uses ~2 vials; an 8-week protocol uses ~4. Step up to 500 mcg and those numbers shrink proportionally. The math is linear and predictable.

Stability is friendly here — reconstituted AOD-9604 lasts 4-6 weeks at fridge temperature, which is longer than any single vial lasts at daily 300 mcg cadence. The constraint is cycle planning, not stability. Most users order the full cycle's vials at once (3-5 vials) so the protocol never pauses for shipping.

Storage and shelf life for AOD-9604

Proper storage of AOD-9604 is crucial for maintaining its potency and stability. Before it’s mixed, the lyophilized (freeze-dried) powder is relatively stable. It should be kept away from light and in a cool environment. The best place for it is in a refrigerator, at temperatures between 2°C and 8°C (36°F and 46°F). While it can survive shipping at ambient temperatures for a short period, long-term storage at room temperature is not advised as it can cause the peptide to slowly degrade over time. Never freeze the unmixed powder.

Once you have reconstituted the peptide by mixing it with bacteriostatic water, it becomes much more fragile. The liquid solution MUST be stored in the refrigerator at all times, again between 2°C and 8°C. Do not leave it out on the counter. The shelf life of reconstituted AOD-9604 is a subject of some debate, but it is generally considered to be potent for up to four weeks when properly refrigerated. After this point, the peptide may begin to break down, and its effectiveness could be diminished. To ensure you are using it within its optimal window, it’s good practice to write the date of reconstitution on the vial itself.

How the AOD-9604 vial duration calculator works

A 5 mg AOD-9604 vial covers 16 doses at 300 mcg — about 2.5 weeks at daily cadence. Step up to 500 mcg and the same vial covers 10 days. Most fat-loss research protocols run 4-12 weeks, so plan 2-5 vials per cycle.

The formula is two divisions. Total doses per vial equals vial mg divided by dose mg, rounded down. Weeks of supply equals total doses divided by doses per week. With a 5 mg vial of AOD-9604, a 0.3 mg dose, and 7 dose per week, the vial covers 16 doses, or about 2.3 weeks of supply.

The three inputs that move the answer: vial mg (set when you bought the vial), dose mg (set by your protocol step), and doses-per-week (set by the peptide's half-life). Once a vial is reconstituted it also has a stability ceiling — most lyophilized peptides reconstituted in BAC water are typically used within four to six weeks of refrigerated storage, so a vial that mathematically lasts twelve weeks may not last twelve weeks in practice.

One of the most practical questions when starting a new protocol is, "How long will my vial last?" The Vial Duration calculator is a planning tool that gives you a clear answer, helping you manage your supplies and budget. It takes the total peptide amount in your vial and divides it by your intended dose to tell you exactly how many doses you can expect to get. This is especially useful for a peptide like AOD-9604, where daily administration is common, as it helps you anticipate when you’ll need to reorder.

Let’s apply this to our running example. You have a 5mg vial of AOD-9604 and you plan to take a daily dose of 0.3mg. First, we convert the vial to milligrams: 5mg is the same as 5000mcg, and your dose is 300mcg. The math is simple: 5000mcg divided by 300mcg per dose equals 16.67 doses. If you’re taking it every day (7 doses per week), your vial will last for about 2.4 weeks (16.67 / 7). Knowing this allows you to plan ahead so you don’t run out unexpectedly mid-protocol.

This calculator becomes even more valuable if your protocol involves titration. You might start with a lower dose of 0.15mg for the first week before increasing to 0.3mg. The tool can help you map this out, showing you how dose adjustments will impact the overall lifespan of your vial. By giving you a precise timeline, this calculator empowers you to manage your AOD-9604 supply chain effectively, ensuring you have what you need to maintain a consistent schedule without any interruptions.

Common AOD-9604 vial-planning mistakes

Storing the mixed, liquid AOD-9604 vial at room temperature or in direct sunlight.
Forgetting to refrigerate the vial after reconstitution, significantly shortening its lifespan.
Shaking the vial like a protein shake after adding water, which can damage the peptide.

Frequently asked questions about AOD-9604 vial duration

How does the AOD-9604 vial duration calculator estimate weeks of supply?

It floors total doses (vial mg ÷ dose mg) then divides by doses per week. For this AOD-9604 example — a 5 mg vial, 0.3 mg per dose, 7 dose/week — that's floor(5 ÷ 0.3) ÷ 7 = about 2.3 weeks. Flooring matters: a partial dose left in the vial doesn't count. AOD-9604 cycles run 4-12 weeks; daily dosing means 2-5 vials per cycle.

Should I plan refills around the math, or around stability?

Whichever runs out first. Math says AOD-9604 at the example dose lasts the calendar weeks shown above. Stability says most reconstituted peptides are typically used within 4–6 weeks of refrigerated storage regardless of how much liquid is left. If the math says 12 weeks but stability caps at 5, plan around 5 — and reconstitute the next vial with less water so you finish it in the stability window. AOD-9604 cycles run 4-12 weeks; daily dosing means 2-5 vials per cycle.

Does titrating the AOD-9604 dose up shorten vial life?

Yes, often dramatically. Doubling the dose halves the doses-per-vial. The calculator shows real-time how a step-up changes the weeks-of-supply line, so you can re-time refill orders before a titration event rather than discovering the gap mid-protocol. AOD-9604 cycles run 4-12 weeks; daily dosing means 2-5 vials per cycle.

What if I take AOD-9604 less often than the default cadence here?

Drop the doses-per-week field. With 7 dose/week the example vial lasts about 2.3 weeks; halving the cadence roughly doubles that, but you'll hit the stability ceiling first. A vial that mathematically covers 16 weeks rarely covers 16 weeks in practice. AOD-9604 cycles run 4-12 weeks; daily dosing means 2-5 vials per cycle.
