Reconstitution (30 mg vial)
Add 3.0 mL bacteriostatic water to a 30 mg lyophilised vial → about 10.0 mg/mL (same concentration as the 20 mg vial when prepared this way).
At 10.0 mg/mL, 1 U on a U‑100 insulin syringe = 0.01 mL ≈ 100 mcg.
Weekly titration
Follow the same milligram/week escalation as the 5 mg and 20 mg guides on this site. The unit / mL table is identical to the 20 mg page because both yield ~10 mg/mL after reconstitution.
| Phase | Weekly dose | Syringe units at 10 mg/mL (mL) |
|---|---|---|
| Weeks 1–4 | 2 mg | 20 units (0.20 mL) |
| Weeks 5–8 | 4 mg | 40 units (0.40 mL) |
| Weeks 9–12 | 6 mg | 60 units (0.60 mL) |
| Weeks 13+ | 8 mg | 80 units (0.80 mL) |
Practical note
A 30 mg vial simply gives you more total mg per vial before you need another vial—useful for higher weekly maintenance without reconstituting as often.
