ARA-290 dosage chart
The units to draw on a U-100 insulin syringe for each ARA-290 dose, by vial size and the water added.
- vial sizes sold
- 10, 16, 100 mg
- approval status
- Not FDA-approved
- in each unit of a U-100 syringe
- 0.01 mL
If you have a vial of ARA-290 and an insulin syringe, the ARA-290 dosage charts on this page show how many units on the syringe match a given amount, so you can read the answer instead of doing the math. There is no approved dose for ARA-290, so the amounts listed here are round figures that make the chart easy to read, not doses we recommend.
- Sizes available: 10 mg, 16 mg, 100 mg
- Status: not FDA-approved for human use; sold as a research chemical
- On a U-100 insulin syringe, 1 unit measures 0.01 mL
ARA-290 dosing chart in units
| Your dose | 10 mg vial + 2 mL | 16 mg vial + 2 mL |
|---|---|---|
| 200 mcg | 4 units | 2.5 units |
| 250 mcg | 5 units | 3.1 units |
| 300 mcg | 6 units | 3.8 units |
| 500 mcg | 10 units | 6.2 units |
| 750 mcg | 15 units | 9.4 units |
| 1.5 mg | 30 units | 18.8 units |
| 2 mg | 40 units | 25 units |
| 3 mg | 60 units | 37.5 units |
| 4 mg | 80 units | 50 units |
Dose rows are round amounts for reading the table, not a suggested dose: no FDA label exists.
Read this first
The powder in a peptide vial is dry, so it needs water before you can measure any of it. That first step of adding water is called reconstitution. The quantity of water you add sets how concentrated each drop is, and for that reason the chart always pairs each vial size with the water amount used.
Amounts can be listed in mcg or in mg. One mcg is a microgram, and a thousand micrograms make one milligram, so 500 mcg is half a milligram. Insulin syringes of the U-100 type carry unit markings rather than millilitres. Each unit measures 0.01 mL, which means 100 units fill 1 mL of liquid.
ARA-290 dosing chart in syringe units
Pick the row that matches your vial and how much water you added, then read across to the amount you need. The cell tells you how much to measure.
| Vial and water | 250 mcg | 500 mcg | 3 mg | 4 mg |
|---|---|---|---|---|
| 10 mg vial + 2 mL water | 5 units | 10 units | 60 units | 80 units |
| 16 mg vial + 2 mL water | 3.1 units | just over 6 units | 37.5 units | 50 units |
| 100 mg vial + 10 mL water | 2.5 units | 5 units | 30 units | 40 units |
A few cells come out as a fraction of a unit. Insulin syringes are usually marked in whole units or half units, so a figure such as 3.1 units falls between two lines and cannot be drawn precisely.
Reconstitution chart by vial size
The unit count you get from one vial shifts with the amount of water used. A smaller amount of water gives a stronger solution and a shorter draw, while a larger amount gives a weaker solution and a longer draw, and the markings on the syringe are easier to read. Each cell below lists the mix strength and the units needed for 1 mg.
| Water added | 10 mg vial | 16 mg vial | 100 mg vial |
|---|---|---|---|
| 1 mL | 10 mg per mL → 10 units | 16 mg per mL → just over 6 units | 100 mg per mL → 1 unit |
| 4 mL | 2.5 mg per mL → 40 units | 4 mg per mL → 25 units | 25 mg per mL → 4 units |
| 10 mL | 1 mg per mL → 100 units | 16 mg in 10 mL → just over 60 units | 10 mg per mL → 10 units |
Mark the water amount on the vial right after you add it. Once the powder dissolves, a vial mixed with 1 mL looks just like one mixed with 4 mL, so the number you write on the label is the only way to know which row of the chart to use.
Is ARA-290 approved?
No. There is no FDA approval for any use in people, and the sellers in our data treat it as a research chemical, and American Peptides says the same on its product page. Because of that, no official label exists that sets out a dose, a schedule or how long use should last, and this page does not attempt to fill the gap. The charts here only convert amounts into syringe units.
ARA-290 reconstitution chart
| Vial | Water added | Strength | Units for a sample dose |
|---|---|---|---|
| 10 mg | 1 mL | 10 mg/mL | 2.5 units for 250 mcg |
| 10 mg | 2 mL | 5 mg/mL | 5 units for 250 mcg |
| 10 mg | 3 mL | 3.333 mg/mL | 7.5 units for 250 mcg |
| 16 mg | 1 mL | 16 mg/mL | 6.2 units for 1 mg |
| 16 mg | 2 mL | 8 mg/mL | 3.1 units for 250 mcg |
| 16 mg | 3 mL | 5.333 mg/mL | 4.7 units for 250 mcg |
Common questions
Working with a 10 mg vial
With 2 mL of water, the vial holds 200 units in total, so 500 mcg comes to 10 units. If you mix the same vial with 1 mL of water instead, 500 mcg is 5 units and 1 mg is 10 units. Because this product is not approved, it is worth talking to a doctor before you use any amount.
When to take ARA-290
Timing belongs to a label, and ARA-290 has none. We do not suggest when during the day to take it, or how long to wait between doses, because no approved source sets either.
What is reconstitution, and what does it do to the dose?
Reconstitution means adding liquid to the dry powder in the vial. This step leaves the amount of ARA-290 in the vial alone and only changes how much liquid that amount is spread across.
