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 AOD-9604

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.

The same 5 mg vial at other water volumes

If the draw is awkward to read, change the water, not 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 lasts in the body

Not well characterised in humans. A decay curve is only drawn where a human half-life is documented, so there is none here. Treat any precise figure for AOD-9604 elsewhere with caution.

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