Dihexa Reconstitution & Dosage Calculator
This free Dihexa calculator turns your vial size, the diluent you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. Dihexa is a small angiotensin IV analog reported to potentiate hepatocyte growth factor signalling, and it is worth knowing before you start that its entire evidence base is rodent work.

Quick summary
- Converts vial size (mg), diluent volume (mL), and a target amount into concentration, draw volume, and U-100 units.
- Reference math for the 10 mg vial size.
- Educational research and measurement tool only — it does not diagnose, treat, or recommend an amount.
What this Dihexa calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
Dihexa ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common Dihexa vial setups; use the custom fields for anything else.
How to use the Dihexa calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your Dihexa vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
Dihexa reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common Dihexa setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 10 mg | 1.0 mL | 10 mg/mL | 10 units |
| 10 mg | 2.0 mL | 5 mg/mL | 20 units |
| 10 mg | 4.0 mL | 2.5 mg/mL | 40 units |
Dihexa amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 0.5 mg (500 mcg) | 0.1 mL | 10 units |
| 1 mg (1000 mcg) | 0.2 mL | 20 units |
| 2 mg (2000 mcg) | 0.4 mL | 40 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 0.5 mg (500 mcg) | 0.2 mL | 20 units |
| 1 mg (1000 mcg) | 0.4 mL | 40 units |
| 2 mg (2000 mcg) | 0.8 mL | 80 units |
Mixing, color & storage tips
Solubility is the first problem
Dihexa is poorly soluble in water. Suppliers commonly specify a co-solvent rather than plain bacteriostatic water, and a vial that will not go clear in water has not failed — it was never going to dissolve in it. Check what your supplier specifies before adding anything.
No human data at all
There is no human trial, no human pharmacokinetics, and no established amount for this compound. Every figure circulating for it is extrapolated from rodent studies. The calculator handles the arithmetic; it cannot supply an amount that does not exist.
Mixing
Add the diluent slowly against the inside wall and swirl gently. Do not shake.
Storage
Keep the dry material cold, dark and dry. Refrigerate once in solution, protect from light, and plan around a limited window.

Dihexa — frequently asked questions
What does this Dihexa calculator tell me?
It converts your vial size, diluent volume, and target amount into concentration in mg/mL, draw volume in mL, and U-100 syringe units. It is a measurement tool, not a recommendation.
Is the Dihexa calculator free?
Yes — free, browser-based, and no account is required.
Does Dihexa dissolve in bacteriostatic water?
Poorly. It has low aqueous solubility and suppliers typically specify a co-solvent. Follow the guidance for your specific product rather than assuming plain bacteriostatic water will work.
Is there an established Dihexa dose?
No. There is no human trial and no human pharmacokinetic data for this compound. Any human figure you encounter is an extrapolation from rodent work, not a measured amount.
Is this medical advice?
No. This page and calculator are for education and research planning only. Products referenced are sold strictly as research chemicals and are not for human or veterinary use.

Dihexa protocol & evidence
There is no established human dosing schedule for Dihexa — the published work is animal or cell-culture research. The protocol page explains what that work does and does not show.
