Both branded and compounded require refrigeration. Improper storage compromises potency.
Refrigeration
Branded pens unopened: 36–46°F (2–8°C). Do not freeze. Once in use, most pens tolerate room temp ≤86°F (30°C) for 28–56 days (varies; check label).
Compounded vials: 36–46°F. Use within beyond-use date on vial.
Do not freeze
Freezing denatures the peptide. Discard if frozen.
Travel
See travel guide. Insulated cooler + ice pack up to ~24 hours. Don't let medication touch ice directly.
Shipping
Reputable providers ship insulated with ice packs. Inspect on arrival. If warm, contact provider before use.
Sharps disposal
FDA-cleared sharps containers required. Many pharmacies provide free disposal. Don't put needles in household trash.
