Thymosin Alpha-1 Dosage Calculator: Reconstitution and Units

To calculate Thymosin Alpha-1 dosage, divide your target dose (mg) by the vial concentration. For a 5 mg vial with 2 mL BAC water: concentration is 2.5 mg/mL. A 1 mg dose equals 0.4 mL (40 U-100 units). A 1.5 mg dose equals 0.6 mL (60 U-100 units) on a U-100 insulin syringe.

How to Calculate Thymosin Alpha-1 Dosage

Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.

  1. Step 1 — Calculate concentration (mg/mL)

    Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg Thymosin Alpha-1 vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.
  2. Step 2 — Calculate draw volume (mL)

    Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.
  3. Step 3 — Convert to U-100 syringe units

    Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.

Dosage Formula

Concentration formula

Concentration (mg/mL) = Vial mg ÷ BAC water mL

Draw volume formula

Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)

U-100 syringe units

U-100 units = Draw volume (mL) × 100

These three formulas apply to any Thymosin Alpha-1 vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

1 mg dose from 5 mg / 2 mL vial

  1. Vial: 5 mg  |  BAC water: 2 mL  |  Target dose: 1 mg
  2. Concentration: 5 ÷ 2 = 2.5 mg/mL
  3. Draw volume: 1 ÷ 2.5 = 0.4 mL
  4. U-100 units: 0.4 × 100 = 40 units

1.5 mg dose from 5 mg / 2 mL vial

  1. Vial: 5 mg  |  BAC water: 2 mL  |  Target dose: 1.5 mg
  2. Concentration: 5 ÷ 2 = 2.5 mg/mL
  3. Draw volume: 1.5 ÷ 2.5 = 0.6 mL
  4. U-100 units: 0.6 × 100 = 60 units

Thymosin Alpha-1 Reconstitution Guide

Thymosin Alpha-1 (Tα1) is an immune-modulating tetradecapeptide typically supplied as a lyophilised powder in 1.5 mg or 5 mg vials. It is generally administered subcutaneously.

  1. Swab both vial stoppers with alcohol swabs and allow to air dry.
  2. Draw 2 mL BAC water for a 5 mg vial (yields 2.5 mg/mL) or 1 mL for a 1.5 mg vial (1.5 mg/mL).
  3. Inject BAC water slowly along the glass wall of the peptide vial.
  4. Gently swirl until the powder dissolves. Do not shake.
  5. Store reconstituted Thymosin Alpha-1 at 2–8 °C and use within 4–6 weeks.

Frequently Asked Questions

What is the standard Thymosin Alpha-1 reconstitution?

A 5 mg vial + 2 mL BAC water = 2.5 mg/mL. At this concentration, a 1 mg dose = 0.4 mL = 40 U-100 units; a 1.5 mg dose = 0.6 mL = 60 U-100 units.

How many doses per Thymosin Alpha-1 vial?

A 5 mg vial at 2.5 mg/mL provides approximately 3–5 doses depending on whether you dose at 1 mg or 1.5 mg per injection.

What are U-100 syringe units?

U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading.

Do I need to recalculate if I change the amount of BAC water?

Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration.

What is Thymosin Alpha-1 researched for?

Thymosin Alpha-1 is an endogenous peptide studied for its role in immune system modulation, T-cell maturation, and innate immunity activation. Research use only.
