How many units is 300 mcg of AOD-9604?

It depends entirely on how much water you added. In a 5 mg vial reconstituted with 2 mL, the concentration is 2.5 mg/mL, so 300 mcg is 0.12 mL, which is 12 units on a U-100 insulin syringe. In the same vial with 1 mL of water it is 6 units, and with 3 mL it is 18 units.

How much bacteriostatic water for a 5 mg AOD-9604 vial?

2 mL is the usual choice. It gives 2.5 mg/mL, which puts the commonly reported range of 200 mcg to 500 mcg between roughly 8 and 20 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many doses are in a 5 mg vial?

Divide 5 by your dose. At 300 mcg that is 16 doses, which at once daily is 16 days.

How many units is 300 mcg of AOD-9604?

In a 5 mg vial with 2 mL of water, 12 units on a U-100 syringe.

Is AOD-9604 the same as HGH fragment 176-191?

AOD-9604 is fragment 176-191 with one modification (a tyrosine at the N-terminus) that stabilises it. Vendors use both names, sometimes for the same product. The dosing arithmetic is identical either way.

About the numbers above

AOD-9604 is a modified fragment of the C-terminal end of human growth hormone (amino acids 176 to 191), studied for fat metabolism without the growth-promoting effects of the full hormone. It reached late-stage trials for obesity and did not meet its endpoints. It is not an approved medicine and is sold for research.

A 5 mg vial holds 5,000 mcg. With 2 mL of water it is 2,500 mcg/mL, so 300 mcg is 0.12 mL, or 12 units. Reported protocols cluster at 250 to 300 mcg once daily.

A 5 mg vial at different water volumes

If the draw feels awkward to read, change the water rather than the dose. The dose stays the same; only the mark moves.

Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
5 mg	1 mL	5 mg/mL	0.06 mL	6 units	16
5 mg	2 mL	2.5 mg/mL	0.12 mL	12 units	16
5 mg	3 mL	1.67 mg/mL	0.18 mL	18 units	16
10 mg	1 mL	10 mg/mL	0.03 mL	3 units	33
10 mg	2 mL	5 mg/mL	0.06 mL	6 units	33
10 mg	3 mL	3.33 mg/mL	0.09 mL	9 units	33

All rows above assume a 300 mcg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

How long it stays in you

Not well characterised in humans. This site only draws a decay curve where a half-life is actually documented in humans, so there is none here. Treat any precise figure you see elsewhere for AOD-9604 with suspicion.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
