For sermorelin, obtain product-specific storage instructions from the dispensing pharmacy. The historical Irish Geref 50 label specified refrigerated storage, and FDA's own shelf-life approval for the US brand used storage at 45°F (7°C) [6] [7]. The brand, Geref, has been gone since FDA withdrew its approvals in 2009 at the maker's request; FDA later found it was not withdrawn for safety or effectiveness reasons [9]. Sermorelin sold now is compounded, and DailyMed carries no sermorelin label as of this update [8].
Historical brand documents specified refrigerated storage
The Irish Medicines Board’s historical Geref 50 product information, revised May 2004 and printed July 2006, gives this storage instruction for its diagnostic ampoule [6]:
Store at 2°C to 8°C. Protect from light.[6]
FDA's own files point the same way. In August 1991 FDA approved a longer shelf life for Geref, from 12 to 24 months, based on stability data for vials stored at 45°F (7°C) [7]. That was the 50-microgram diagnostic vial, but it shows the brand's stability case was built on cold storage.
These records cover particular historical products. The Irish document also calls for preparation immediately before use and discarding what remains; it does not validate a multi-use compounded vial. Neither the Irish ampoule instructions nor the US shelf-life letter establishes storage or an after-opening window for a preparation dispensed today.
Your pharmacy label is now the instruction that applies
For compounded sermorelin, the pharmacy that made it decides how it should be stored and how long it is good for. Compounded drugs are not FDA-approved, which means FDA does not verify their safety, effectiveness or quality before they are sold [10]. There is no FDA storage instruction to fall back on.
Look for two things on your label: a storage temperature and a date. Pharmacies call that date the beyond-use date, the last day the preparation should be used. It can differ between two pharmacies making what looks like the same product, because the formula, the container and the testing behind it differ.

Online storage windows disagree because products differ
You'll find sermorelin storage advice ranging from a few days to three months, and some pages suggest freezing. A quoted window may come from a particular pharmacy preparation or may be unsupported. Powder vials, mixed vials, tablets and nasal sprays can differ in formulation, container and handling requirements.
Even FDA-approved versions of one peptide can store differently. The tesamorelin label notes that its two formulations differ in dosage, preparation and storage requirements [11]. Compounded sermorelin from different pharmacies has at least as much room to vary.
If sermorelin was left out, call the pharmacy
Our search did not identify a room-temperature stability study validating your dispensed sermorelin preparation [12]. The dispensing pharmacy should assess the formulation, documented storage limits and the actual excursion; ask it to contact the manufacturer or compounder when necessary.
- Note how long it was out and roughly how warm it got.
- Keep it the way your label says while you wait for an answer.
- Call the dispensing pharmacy, not the telehealth app, and ask whether to use it.
- If a shipment arrives warm, report it to the pharmacy the same day.
Four questions to ask before your first shipment
Ask these before you start, so you aren't guessing when a delivery sits on the porch:
- What temperature should this be stored at, before and after opening?
- What is the use-by date, and does it change once the vial is opened or mixed?
- Does it ship cold, and what should I do if it arrives warm?
- Which pharmacy makes it, and how do I reach them directly?
That last question matters. Our provider checks look for publicly named pharmacy facilities. That does not confirm which facility will dispense your order; ask for its direct contact details. When and how prescribers schedule sermorelin is covered in when to take sermorelin.
Tablets, troches and nasal sprays have their own labels
Telehealth providers sell sermorelin in several forms, and each pharmacy label sets its own storage. The table gives selected currently checked examples, rather than a complete market list. Whether the oral forms work is a separate question, covered in do sermorelin tablets work.
| Form | Providers listing it |
|---|---|
| Injection (vial) | Strut Health, Gala, AHBARx and ARSYNL Rx |
| Dissolving tablet, film or troche | Strut Health and AHBARx |
