What is Dihexa?
Dihexa is a small synthetic compound that grew out of angiotensin IV research at Washington State University. Chemically it is described as N-hexanoic-Tyr-Ile-(6) aminohexanoic amide: a short, modified peptide chain with a fatty hexanoic cap, which makes it far more lipophilic than a typical research peptide. People searching for “dihexa dosage” usually hold a vial and want to know how the numbers on its label turn into marks on a syringe. That arithmetic is what this page covers.
Research interest in Dihexa has centered on laboratory and animal work involving the hepatocyte growth factor (HGF) and c-Met signaling system. That is a description of what scientists have studied, not evidence of any effect in people, and nothing here should be read as a claim about benefits. Listings for “dihexa peptide injection” refer to research-labeled vials of freeze-dried powder, and you can compare it with other labeled calculators in the peptide library.
How much BAC water for a Dihexa vial?
Dihexa vials are most often sold as 5 mg and 10 mg. The volume of bacteriostatic water added does not change how much compound is in the vial; it only changes how concentrated the solution is. More water spreads the same milligrams across more syringe units, so each unit holds fewer micrograms. Less water does the opposite.
The chart below shows micrograms per unit on a U-100 syringe for each vial size and a range of water volumes. Read down a column to see how the same vial behaves with different volumes.
| BAC water | 5 mg vial | 10 mg vial |
|---|---|---|
| 1 mL | 50 mcg/unit 5 mg/mL | 100 mcg/unit 10 mg/mL |
| 2 mL | 25 mcg/unit 2.5 mg/mL | 50 mcg/unit 5 mg/mL |
| 3 mL | 16.67 mcg/unit 1.667 mg/mL | 33.33 mcg/unit 3.333 mg/mL |
| 5 mL | 10 mcg/unit 1 mg/mL | 20 mcg/unit 2 mg/mL |
Each cell shows mcg per unit on a U-100 syringe (100 units = 1 mL) and the resulting concentration.
None of these volumes is a recommendation. They are simply the combinations people ask about most. The general logic behind every column is explained in the guide to the BAC water to peptide ratio.
Worked example: Dihexa 10mg in syringe units
The calculator works in three steps: vial milligrams divided by water millilitres gives concentration; the amount you enter divided by that concentration gives a volume in mL; and that volume multiplied by 100 gives units on a U-100 syringe. For example, if the amount you already have is the figure shown below and the vial is a Dihexa 10mg vial mixed with the stated water volume:
The math: 10 mg ÷ 2 mL = 5 mg/mL (5,000 mcg/mL), which is 50 mcg per unit. 500 mcg ÷ 5,000 mcg/mL = 0.1 mL = 10 units on a U-100 syringe.
The amount in that sentence is an arbitrary figure picked because it divides cleanly. Swap in your own vial size, water volume, and amount and the same three steps apply. Remember that 1 mg = 1,000 mcg, so check whether your figure is in mg or mcg before you type it. If units and millilitres still feel slippery, the U-100 syringe units to mL chart lays them side by side.
Dihexa dosage calculator: what the numbers mean
Although the search term is “dihexa dosage,” this is a conversion tool, not a dosing guide. It takes a number you already have and expresses it as a volume and a syringe mark. It does not know who you are, what the product is, or whether any amount is appropriate, and it never proposes one. There is no established human dose for Dihexa, and the site does not publish one.
What the calculator can do well is catch arithmetic mistakes. The most common errors are typing mg where mcg was meant (an error of 1,000 times), entering the water volume you planned rather than the volume you actually added, and reading a U-100 scale on a syringe that is not U-100. The chart and the calculator above both use the same formula, so if they disagree, an input is wrong. To check the math by hand, follow the steps in how to check peptide calculator math.
Dihexa reconstitution notes from suppliers
Because of its hexanoic cap and small size, Dihexa behaves less like a water-loving peptide than many compounds in the library. Some supplier listings describe it as poorly soluble in plain water, and some specify a particular solvent or a carrier rather than bacteriostatic water alone. Other listings sell it in forms that are not vials at all, such as powders or capsules, and the calculator on this page applies only to a vial with a stated milligram content that is dissolved in a measured volume of liquid.
If a product label or supplier sheet names a solvent, a volume, or a storage condition, that instruction takes priority over any general page, including this one. Handling, sterility, and storage should follow the product labeling and a qualified professional. For general background on the process, see how peptide reconstitution works.
Is Dihexa FDA-approved?
No. Dihexa is not an FDA-approved drug, and there is no approved medicine containing it. Vials sold online are labeled for research use, and a research label says nothing about identity, purity, sterility, or suitability for any use in people. A correct calculation cannot verify any of those things either.
Dihexa FAQ
Does this page tell me a Dihexa dosage?
No. The calculator converts an amount you already have into mL and U-100 syringe units. It does not recommend an amount, a schedule, or any use.
How much BAC water goes in a Dihexa 10mg vial?
There is no single correct volume. The chart shows how different water volumes change mcg per unit. If the product label names a volume or a solvent, the label takes priority.
Why does adding more water lower the mcg per unit?
The milligrams in the vial stay the same. Spreading them across more liquid means each 0.01 mL unit contains less of the compound.
Is Dihexa a peptide?
It is a small modified peptide-like compound derived from angiotensin IV research, with a hexanoic acid cap that makes it more fat-soluble than most research peptides.
Does the calculator work for Dihexa capsules?
No. It only applies to a vial with a known milligram content dissolved in a measured volume of liquid.
