Dulaglutide Reconstitution Calculator

A long-acting GLP-1 receptor agonist Fc-fusion referenced in comparative metabolic research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted Dulaglutide preparation, plus the mass-to-molar conversions for its stated molecular weight. Everything runs in your browser; plan entries stay in this browser, with optional device-local saving and calendar export.

Syringe capacity

Whole administrations exclude dead space, handling losses and expiry. A calculated quantity is not a guarantee of usable supply. No rounding to a nearby syringe mark is performed.

Protocol schedule

Schedule an existing prescribed or approved protocol. This tool cannot determine how often you can safely take a peptide. Frequency, dose, reconstitution, storage and discard instructions must come from the product label and your clinician or pharmacist.

A separate worked example, step by step

This separate arithmetic example uses a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of Dulaglutide and not an amount anyone should draw — these figures only illustrate the arithmetic.

  1. Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for Dulaglutide is approximately 0.04188 mM at its stated molecular weight.
  2. Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
  3. Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
  4. Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for Dulaglutide

Derived from the molecular weight recorded on the Dulaglutide entry: ~59700 g/mol — the entry states this as an approximate figure, so the equivalents below are approximate too. Concentration in molar units is what an in-vitro protocol is usually specified in.

Mass to molar conversions for Dulaglutide at its stated molecular weight.
QuantityMolar equivalent
1 mg of Dulaglutide16.75 nmol (0.01675 µmol)
1 mcg of Dulaglutide0.01675 nmol
A 1 mg/mL solution0.01675 mM (16.75 µM)

Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Reconstitution recorded for Dulaglutide

Lyophilized Fc-fusion protein typically reconstituted with bacteriostatic water; refrigerate and protect from light after reconstitution.

Handling questions for Dulaglutide

How should research-grade dulaglutide be stored?

As an Fc-fusion protein it is temperature-sensitive; lyophilized material is stored cold, reconstituted with bacteriostatic water, kept refrigerated, and protected from light and freeze-thaw. Expect a COA with purity (commonly greater than or equal to 98%) and identity confirmation as the standard quality reference.
