## FAQ

### How much sterile water do you add to a 2 mg tesamorelin vial?

The EGRIFTA SV label calls for 0.5 mL of Sterile Water for Injection per 2 mg vial, which works out to a 4 mg/mL concentration.

### Can you shake a tesamorelin vial to mix it faster?

No. The EGRIFTA SV label and similar lyophilized-peptide labels call for gentle rolling or swirling, never shaking.

### Can you refrigerate reconstituted tesamorelin for later use?

No. The EGRIFTA SV label says to use the reconstituted solution right away and not to freeze or refrigerate it after mixing.

### What's the difference between sterile water and bacteriostatic water for reconstitution?

Sterile Water for Injection has no preservative and is single-dose; bacteriostatic water contains a preservative (0.9% benzyl alcohol in ours) and is built for multiple draws from one vial.

### How do you know if a reconstituted vial is bad?

Check that it's clear and colorless with no particles. Cloudy, discolored, or particulate solution shouldn't be used, per the FDA labels reviewed.

### Why does the diluent go in along the vial wall instead of straight onto the powder?

Other lyophilized protein labels, like infliximab's, direct the diluent stream to the glass wall of the vial; the label gives the instruction without stating a reason.

### How should an intact tesamorelin vial be stored before mixing?

At room temperature, 20-25°C, protected from light in its original box, per the EGRIFTA SV label.
