Reconstitution protocol — 10 mg vial + 2 mL Bacteriostatic water

Standard multi-draw laboratory diluent; supports refrigerated storage of the reconstituted solution.

1. Prepare the workspace. Wipe down the work surface and the septa of both vials with 70% isopropyl alcohol. Allow both to air-dry fully before piercing.
2. Equilibrate to room temperature. Remove the 10 mg lyophilized vial from cold storage and let it stand 15–20 minutes. Reconstituting a cold vial can cause condensation inside.
3. Draw the diluent. Using a sterile syringe, draw exactly 2 mL of bacteriostatic water.
4. Add slowly against the vial wall. Insert the needle at an angle and release the 2 mL down the inside wall of the peptide vial — never jet the stream directly onto the lyophilized cake.
5. Swirl, do not shake. Gently roll the vial between your fingers until the cake fully dissolves. The solution should be clear and particle-free; discard if cloudy after 10 minutes.
6. Verify the concentration. The vial now holds 5 mg/mL (5,000 mcg/mL). Label the vial with the concentration, diluent, date, and batch number from the COA.
7. Store correctly. Refrigerate at 2–8 °C, protected from light. Do not freeze a reconstituted vial unless the batch documentation specifies it.
8. Record and draw. For each research draw of 500 mcg, pull 0.1 mL (10 U-100 units) and log it against the batch record.
