AOD-9604 Dosage Guide for Fat Loss

AOD-9604 is a synthetic fragment of the human growth hormone molecule, corresponding to the 176-191 amino acid region at the tail of the chain. It is studied in laboratory and animal models for pathways linked to fat metabolism, and it ships as a freeze-dried (lyophilized) powder, commonly in a 2 mg or 5 mg vial. Like any peptide, it has to be reconstituted with bacteriostatic water before a volume can be measured. This guide covers the arithmetic behind the commonly cited 300 to 500 mcg reference range, how weight is sometimes used to band that figure, and why reference protocols cap the dose rather than scaling it up.

Everything here is third-person reference information for research and educational use. It is not dosing advice, and AOD-9604 is not approved for human consumption. Any decision about whether or how much to use belongs with a licensed clinician. To run your own numbers instead of the worked examples below, start from the peptide reference hub and the calculators it links.

The reference range: 300 to 500 mcg

Most reference material discusses AOD-9604 in micrograms (mcg), not milligrams, because the per-draw figures are small. The range cited across the literature sits between 300 mcg and 500 mcg per draw, often described as a single daily draw. For context, 300 mcg is 0.3 mg and 500 mcg is 0.5 mg, so a 5 mg vial holds somewhere between 10 and roughly 16 reference draws depending on which end of the band you compute from.

• 300 mcg = 0.3 mg. A 5 mg vial holds about 16 draws at this figure.
• 400 mcg = 0.4 mg. A 5 mg vial holds about 12 draws.
• 500 mcg = 0.5 mg. A 5 mg vial holds 10 draws.

Weight-banded dosing, explained

Some reference frameworks tie the position within the 300 to 500 mcg band loosely to body weight, putting lighter individuals toward the lower end and heavier individuals toward the upper end. This is a banding convention, not a strict mcg-per-kilogram formula like you see with some other peptides. A common way it is laid out:

• Lower body weight: the figure sits near 300 mcg.
• Mid range: around 400 mcg.
• Higher body weight: toward 500 mcg.

The important structural point is that the band is narrow and it has a ceiling. Weight nudges you within 300 to 500 mcg; it does not push you past 500. That ceiling is the whole reason the range exists as a reference, and it leads directly to the next section.

Why more is not better

It is tempting to assume that if 500 mcg does something, 1,000 mcg does twice as much. Reference material on AOD-9604 does not describe it that way. The range is bounded at the top because the studied pathways are thought to respond up to a point and then flatten, so additional powder past the band is generally framed as wasted material rather than added effect. Doubling the draw doubles your cost and empties the vial twice as fast without a matching change described in the literature.

Reconstitution math for a 5 mg vial

Reconstitution reduces to one concentration value and two conversions. You need the vial strength in milligrams, the bacteriostatic water you add in milliliters, and the draw you want to express. A 5 mg vial in 1 mL gives 5 mg/mL; in 2 mL it gives 2.5 mg/mL. The lower concentration spreads each draw across more units, which can be easier to read on a syringe barrel for these small mcg figures.

• Concentration = vial strength / water volume. 5 mg in 2 mL = 2.5 mg/mL.
• Draw volume = dose / concentration. 0.5 mg at 2.5 mg/mL = 0.2 mL.
• Units = draw volume x 100 on a U-100 insulin syringe. 0.2 mL = 20 units.

Worked at 2.5 mg/mL (a 5 mg vial in 2 mL): 300 mcg is 12 units, 400 mcg is 16 units, and 500 mcg is 20 units. At 5 mg/mL (the same vial in 1 mL) those halve to 6, 8, and 10 units. The reconstitution calculator and the mg to units converter handle these conversions for any vial and water combination.

• 300 mcg: 12 units at 2.5 mg/mL, 6 units at 5 mg/mL
• 400 mcg: 16 units at 2.5 mg/mL, 8 units at 5 mg/mL
• 500 mcg: 20 units at 2.5 mg/mL, 10 units at 5 mg/mL

The 8 to 12 week cycle structure

Reference protocols commonly frame AOD-9604 as a timed cycle rather than open-ended use, with 8 to 12 weeks the span cited most often. The logic mirrors how other peptides are discussed: a defined window, then a break before any repeat. The per-draw figure stays inside the 300 to 500 mcg band for the whole cycle; what the cycle length does is bound the total exposure, not change the daily arithmetic. See how long to cycle peptides for the general on-off reasoning.

A quick total: at 500 mcg daily, a 5 mg vial of liquid covers 10 draws, so roughly three to four vials span an 8 week cycle and four to six span 12 weeks at that figure. These are arithmetic illustrations of vial throughput, not recommendations.

Handling and storage notes

General references describe reconstituted peptides as kept refrigerated and used within roughly a few weeks. Bacteriostatic water (saline with benzyl alcohol) is the usual diluent for multi-draw vials because the preservative limits microbial growth between draws. Aim the water down the vial wall rather than at the powder, and swirl rather than shake to avoid foaming. See how to reconstitute peptides for the full handling sequence.
