HCG dosing chart (IU to units)
HCG sits in PinPoint's ancillary category under the identity human chorionic gonadotropin. This entry is measured in IU, including its documented 5,000 IU vial. The chart's amount column keeps IU separate from the U-100 numbers that describe syringe volume. The cited prescribing information is for Novarel.
Vial concentration
Water mL is treated as final solution mL in these columns.
| Vial contents | 1 mL water | 2 mL water | 3 mL water |
|---|---|---|---|
| 5000 IU | 5000 IU/mL | 2500 IU/mL | 1666.6667 IU/mL |
Vial source: PinPoint/Data/CompoundLibrary.swift, line 563, the HCG entry. One documented amount is available.

How to read this chart
Find the concentration column. Divide the amount by that concentration. Multiply the mL value by 100 for U-100 units. Match the amount units before dividing.
units = amount ÷ (vial IU ÷ water mL) × 100
Amount and volume
HCG IU measures activity; U-100 units mark volume. Here, 100 syringe units equals 1 mL. Read the full conversion guide.
Two kinds of units on one page
The letters IU refer to compound activity in the HCG record. U-100 syringe units are volume markings, with 100 markings corresponding to 1 mL. For a 5,000 IU vial represented in 2 mL, each milliliter contains 2,500 IU and each syringe unit corresponds to 25 IU. A line reading 500 IU consequently maps to 20 U-100 units. Reading both labels is essential here because the word units appears in two contexts that do not share the same numerical scale.
The HCG timing fields
PinPoint stores a 33-hour half-life for HCG, along with a six-hour peak-time input and a base bioavailability value of 1.0. The last value is 100% in the model's percentage notation. Its schedule metadata lists Every other day, Three times weekly, and Twice weekly. Those options describe intervals of logged events, while the 33-hour field sets an elimination timescale between their timestamps. Calendar spacing and elapsed hours can differ, especially across a repeating every-other-day sequence, so the time attached to each entry remains meaningful.
Label source and administration routes
The library assigns HCG an FDA-approved research status and includes subcutaneous and intramuscular among its route fields. Both the pharmacology note and the documented vial amount point to prescribing-label sources. This differs from the supplier-catalog vial citations used by most peptide entries in the directory. The selected HCG package fact is 5,000 IU in a multiple-dose vial. Keeping that activity-based amount throughout the calculation avoids introducing a milligram conversion into a page whose two tables can be evaluated entirely in IU and mL.
From vial fractions to liquid volume
HCG has no preset amounts in the website's compound snapshot. The five table rows instead represent 100, 250, 500, 1,000, and 2,500 IU derived from the vial's total. The 2,500 IU row is one half of the vial, making its volumes 0.5, 1, and 1.5 mL across the three columns. Only the 3 mL column takes that half-vial example beyond the one-milliliter syringe reference. The activity amount is identical in all three cells; it is the dilution arithmetic that changes the volume.
Questions about the conversion
What concentration is HCG at 5000 IU in 1 mL?
5000 IU divided by 1 mL is 5000 IU per mL. That volume spans 100 U-100 syringe units.
How does 2 mL change the concentration of this HCG vial?
5000 IU divided by 2 mL is 2500 IU per mL, half the concentration in the 1 mL column.
What does the 3 mL column mean for HCG?
5000 IU divided by 3 mL is approximately 1666.6667 IU per mL. The full 3 mL volume corresponds to 300 U-100 units.
How many units is 500 IU of HCG from this vial in 2 mL?
500 IU divided by 2500 IU per mL is 0.2 mL, or 20 U-100 units.
How many units is the 500 IU cited amount of HCG from a 5000 IU vial in 2 mL?
The arithmetic is 500 IU ÷ 2500 IU/mL × 100 = 20 U-100 units (0.2 mL). The amount is cited in HCG prescribing information (Novarel, 2025). Male hypogonadotropic hypogonadism; endpoint of the stated 500–1,000 IU range.
