Everything you need at a glance — formulas, rules of thumb, storage timelines, purity benchmarks, and unit conversions.

Reconstitution Math

Concentrationmg × 1000 ÷ mL BAC = mcg/mL

Dose volumemcg dose ÷ mcg/mL = mL to draw

U-100 unitsmL × 100 = units on syringe

Common ratio5 mg + 2 mL = 2,500 mcg/mL

250 mcg dose250 ÷ 2500 = 0.10 mL = 10 units

500 mcg dose500 ÷ 2500 = 0.20 mL = 20 units

Storage At-a-Glance

Lyophilized (frozen)-20 to -80°C · 2+ yrs

Lyophilized (fridge)2–8°C · 6–12 months

Reconstituted (BAC)2–8°C · 4–8 weeks

Reconstituted (sterile)2–8°C · 24 hrs only

NeverFreeze reconstituted!

Unit Conversions

1 gram (g)= 1,000 mg

1 milligram (mg)= 1,000 mcg

1 mcg= 0.001 mg

1 mL= 100 U-100 units

0.1 mL= 10 units

0.01 mL= 1 unit

1 IU (GH)≈ 0.333 mg (approx.)

Top 10 Handling Rules

1NEVER shake — swirl only
2Swab stoppers with 70% IPA
3Direct diluent down glass wall
4Inspect: clear = use, cloudy = discard
5Label everything — name + date + conc.
6Never freeze reconstituted solution
7Keep away from light at all times
8Use fresh U-100 syringe each draw
9Check reconstitution date before using
10When in doubt, discard and reconstitute fresh
