5mg vial + 2mL BAC water = 2 units = 50mcg — Amounts listed in the Dosify Me data: 50-200mcg — Frequency: daily — Best taken: bedtime

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.
Vial sizes up to 5 mg are mixed to 2.5 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 5 mg | 2.00 mL | 2.5 mg/mL |
| 10 mg* | 3.00 mL | 3.33 mg/mL |
* This size is conventionally mixed more concentrated rather than diluted further — fewer units per dose than smaller vials of this peptide.
On a standard 100-unit (1 mL) insulin syringe, for vials mixed to 2.5 mg/mL (sizes marked * are more concentrated and need fewer units):
| Dose | Syringe units |
|---|---|
| 50 mcg | 2.0 units |
| 100 mcg | 4.0 units |
| 200 mcg | 8.0 units |
Amounts listed in the Dosify Me data: 50–200 mcg. Frequency: daily. Timing: bedtime.
The 5mg reference vial mixes to 2.5mg/mL. Larger vial size options are capped at ~3mL BAC water instead of diluted further, so they come out more concentrated (fewer units per dose) than this reference size.
Check one row of the table above: 50 mcg is 0.05 mg; 0.05 mg ÷ 2.5 mg/mL = 0.02 mL; 0.02 mL × 100 = 2 units.

VIP is a vasodilator — in a controlled human infusion study it caused flushing and lowered vascular resistance in the forearm, though average blood pressure did not change significantly at the dose tested. Combining it with blood pressure medication or other vasodilating drugs (nitrates, PDE5 inhibitors) could still add up to more of a drop than either alone, but no one has studied the pairing. Talk to your prescribing doctor before combining.

At 2.5 mg/mL (the standard mix for vials up to 5 mg), 50 mcg of VIP is 2.0 units on a 100-unit insulin syringe (0.020 mL).
At 2.5 mg/mL (the standard mix for vials up to 5 mg), 100 mcg of VIP is 4.0 units on a 100-unit insulin syringe (0.040 mL).
At 2.5 mg/mL (the standard mix for vials up to 5 mg), 200 mcg of VIP is 8.0 units on a 100-unit insulin syringe (0.080 mL).
2.00 mL, which gives 2.5 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
3.00 mL, which gives 3.33 mg/mL. This size holds at most 3 mL of water, so it is mixed more concentrated and the same dose is fewer units than from a smaller vial.
Daily. Bedtime Typical cycle: 4 weeks on, ~2 weeks off; repeat 2–3×/year.

Figures come from the Dosify Me compound database for VIP: concentration is the vial amount ÷ the water volume, and syringe units are the volume in mL × 100 on a U-100 syringe.
