What is AOD-9604?

What the compound is

AOD-9604 is a short synthetic peptide, categorized here as metabolic based on how it is marketed rather than on any confirmed effect. It is sold as a lyophilized powder in sealed vials, meaning the peptide arrives as a dry solid and must be dissolved before any volume can be measured.

The sizes that appear in listings are 2 mg and 5 mg per vial. The number on the label refers to the mass of peptide in the vial, not to a dose and not to a volume. A vial contains what it contains regardless of how much water is later added to it.

This site does not evaluate whether AOD-9604 does anything. That question requires clinical review, and this page has none. What follows is arithmetic.

Regulatory status

AOD-9604 is not approved by any regulator for human use. That is the entire status. It is not approved with restrictions, not approved for a narrow indication, not pending in a way that changes anything. No approval exists.

A practical consequence is that nothing about the supply chain is guaranteed. Approved drugs carry identity, purity and sterility requirements enforced by a regulator. Research chemicals do not. The label mass of 2 mg or 5 mg is a claim by the seller, and the concentration figures on this page inherit that assumption. If the vial does not contain what the label says, every number computed downstream is wrong by the same proportion.

This page cannot tell you whether a given vial is what it claims to be, and it cannot tell you whether using it is safe or legal where you are.

What is not known

There is no reliable human pharmacokinetic data for AOD-9604 that this site is willing to rely on. That means no half life figure, no clearance time, no statement about how repeated administration accumulates in the body, and no duration of effect.

Those four things are what a person usually wants when they ask about a compound, and their absence is not a gap this page can paper over. Numbers circulate for peptides like this one. Without a traceable source they are guesses wearing a decimal point, and reproducing them would make this page a laundering step for someone else's invention.

The consequence for the reader is direct. Any question of the form "how often" or "how long" cannot be answered here. The arithmetic below covers concentration and volume only. Those are properties of the vial and the water, not of the body, which is exactly why they can be computed with confidence.

Reading the concentration table

Concentration is peptide mass divided by water volume. The table on this page runs both vial sizes against 1, 2 and 3 mL of bacteriostatic water. Three things in it are worth pulling out.

First, doubling the water halves the concentration. A 2 mg vial goes from 2 mg/mL in 1 mL to 1 mg/mL in 2 mL. The peptide quantity never changes. Only its dilution does, which changes how many syringe units correspond to a given mass.

Second, two different rows can land close together. A 5 mg vial in 2 mL gives 2.5 mg/mL, which sits near the 2 mg/mL of a 2 mg vial in 1 mL. Vials of different sizes can produce similar concentrations, so the concentration alone does not tell you which vial you are holding. Label the vial with both the mass and the water volume you used.

Third, 3 mL produces repeating decimals: 0.67 mg/mL from a 2 mg vial, 1.67 mg/mL from a 5 mg vial. These are rounded. Rounding error is small but it compounds when you work backward from a target mass to a syringe volume, and it is a reason many people prefer water volumes that divide cleanly.

How concentration relates to what you draw

A syringe measures volume, not mass. To convert a target mass into a volume you divide the mass by the concentration. The listings on this site show dose amounts of 0.25 mg, 0.3 mg and 0.5 mg, and those are observations of what vendors print, not recommendations.

The choice of water volume determines how much liquid a given mass occupies. More water means more volume per unit of mass, which spreads the measurement across more syringe markings. Less water concentrates it into a smaller span, where a small error in the plunger position corresponds to a larger error in mass.

This page will not tell you which water volume to use or which mass to target. Both are clinical decisions. What the table gives you is the conversion factor between the two units, so that whatever you decide, the arithmetic connecting vial to syringe is explicit rather than assumed.

What we do not know

We hold no reliable human pharmacokinetic data for AOD-9604, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

Is AOD-9604 approved anywhere?

No. It is not approved by any regulator for human use. It is sold as a research chemical, which means no regulator verifies its identity, purity or sterility.

What is the half life of AOD-9604?

This site holds no reliable human pharmacokinetic data for AOD-9604 and makes no half life claim. The same applies to clearance time and accumulation. Figures circulating elsewhere are not sourced in a way this page can verify.

How much water should I add to the vial?

That is a decision this page does not make for you. The table shows what 1, 2 and 3 mL produce for both the 2 mg and 5 mg vials, so you can see the concentration each choice yields. The tradeoff is between fewer syringe markings per dose and more.

Does a 5 mg vial mean a bigger dose than a 2 mg vial?

No. The vial size is the total peptide in the container, not the amount taken at once. A 5 mg vial simply holds more peptide and therefore more measured volumes at the same concentration. How that total is divided is a separate question this page does not answer.

Why do some rows in the table show repeating decimals?

Dividing 2 mg or 5 mg by 3 mL does not produce a clean figure, so 0.67 mg/mL and 1.67 mg/mL are rounded. The rounding is minor on its own but carries through any conversion you do from mass to volume.

Does AOD-9604 work?

This page does not answer that. It has no medical review and evaluates no efficacy claims. It computes concentration from vial mass and water volume, and nothing beyond that.
