Compounded tirzepatide reconstitution — step-by-step with photos

Not a dumb question at all. For reconstitution (adding BAC water): Yes, use a larger syringe. 3mL or 5mL with an 18ga blunt tip needle works great. Draw up the BAC water, insert into vial, push slowly. For injection: - If your dose is ≤50 units (0.5mL): use a 0.5mL syringe — the markings are spaced wider so it's more accurate - If your dose is >50 units: use a 1mL syringe 29ga or 31ga needle, 1/2 inch, subcutaneous. You'll barely feel it.

Pharmacy tech chiming in — a few things people get wrong: 1. BAC water vs sterile water: BAC water (bacteriostatic, contains 0.9% benzyl alcohol) for multi-use vials. Sterile water for single use ONLY — no preservative means bacteria can grow. 2. Don't use saline. Bacteriostatic saline changes the osmolarity and can affect peptide stability. 3. Draw technique matters: After inserting needle into vial, push the BAC water in, then before withdrawing, pull back slightly to equalize pressure. This prevents loss of peptide solution. 4. Storage: Reconstituted tirz is stable for 28 days refrigerated (36-46°F / 2-8°C). Don't freeze it, don't leave it at room temp.
