Does sermorelin need to be refrigerated?
By Ray Kaminski, who covers specialty pharmacy pricing and compounding economics.
Updated September 2026.
The sellers that answer say yes: 3 of the 88 sermorelin pages we hold give a storage temperature, and all 3 say 36–46 °F (2–8 °C). The FDA dated the original Geref, a freeze-dried powder, for 24 months stored at 7 °C (FDA approval letter, 1991), and for sermorelin after it’s mixed, no seller prints a time and no document we hold sets one.
That leaves the pharmacy that dispensed your vial as the one source for how to keep it, and most sellers don’t say who that is.

Sellers that pay us a commission come first in their group, and their button says so. That position is the only thing paying us buys. Below it, each group is ordered by what each seller states about its own figure: the kind of price first, then the figure itself. The price, the dose, the score and the review read the same either way. This is a short list on a page about something else; the full board is on compare sermorelin sellers. Every figure above was read from the seller’s own page in September 2026. None of these 4 sellers names the pharmacy that compounds its sermorelin. A pharmacy named on a seller’s GLP-1 pages does not count: it says nothing about who makes this drug.
What sellers print
Very little. 3 of the 88 sermorelin pages we hold give a temperature to keep it at, Get Thin MD, Ivy Rx and Vytora Health, and all 3 give the same one: 36–46 °F (2–8 °C). The other 85 print none.

Each seller’s own sermorelin page, captured September 2026. Found with a wide search for refrigeration, storage, temperature, cold-shipping and mixing words, then every hit read. A question in a closed FAQ is counted as asked: the answer may be one click away.
Get Thin MD is the one page that also deals with the vial after it has been mixed.
“Store unopened vials in the refrigerator at 36°F to 46°F (2°C to 8°C)”
“Once reconstituted, keep refrigerated and use within the timeframe specified by your pharmacy”
The second line is the telling one. The one seller that addresses a mixed vial doesn’t print how long it lasts; it hands the question to the pharmacy. Invyncible does the same for storage in general: “Medication concentration, vial size, supplies, storage requirements and availability may vary by prescription, pharmacy and state.”
A further 6 pages raise the question and keep the answer out of sight, each in a closed FAQ: LaSara Medical Group, Liberty, Luvo Health, MadeMed, System Labs and TeleZen MD. The answer may be one click away; it isn’t on the page a buyer reads first.
What the FDA record says
The original Geref was a freeze-dried powder: the FDA’s 1991 chemistry review lists its dosage form as “Lyophilized Powder”. That year the agency extended its shelf life, and the approval letter names the temperature.
“The supplement provides for data to support the extension of the expiration date for Geref from 12 to 24 months when stored at 7°C.”
Seven degrees Celsius sits inside the 2–8 °C band the 3 sellers print. Drugs@FDA holds no Geref label; its page for the original application lists two 1991 approval packages, and this is the one about shelf life (Drugs@FDA, NDA 019863; FDA approval letter, 1991).
How that squares with how it ships
6 of the 88 pages say their sermorelin travels cold, packed with ice or in temperature-controlled packaging: Ivy Rx, Liberty, PepHaūs, RxION Health, The Edit and Vytora Health. Only 2 of those, Ivy Rx and Vytora Health, also print the temperature to keep it at once it arrives, and Get Thin MD prints the temperature without saying how it ships.
One page says what happens when the cold chain doesn’t hold, and it’s the only one that puts a number on warm storage.
“It is common for medication to arrive with ice packs melted — this is normal. The medication is stable for up to 56 days at up to 86°F, and up to 3 days at 104°F.”
Vytora Health attaches no source to those figures, and nothing in the record we hold tests them. The same page adds that “medication arriving warm does not typically qualify for a refund”, which is a term worth reading before the first box ships, next to what a sermorelin refund covers.
How it ships only matters if it ships to you. 19 of 89 sellers state where they will ship, and shipping is one of the things a sermorelin price may or may not include.
Where these counts come from
Every “N of 88” on this page counts the 88 sermorelin seller pages we could read, in September 2026. The board lists 89 companies: the extra one publishes no sermorelin page we could read, so it is on the board and in none of these counts.
We counted what a seller printed where a buyer can see it, in September 2026. A price or an answer behind an intake form or a closed FAQ is not counted, which is why a count of 88 is a count of what these pages publish rather than of what these companies would tell you if you asked.
Questions
Does sermorelin need to be refrigerated before it’s mixed?
Every seller that answers says to keep it cold: 3 of 88 pages print 36–46 °F (2–8 °C). The original Geref, a freeze-dried powder, was dated for 24 months stored at 7 °C. The pharmacy that made your vial is the source for its storage.
How long does sermorelin last after it’s mixed?
No seller page we hold prints a time. The one that addresses a mixed vial, Get Thin MD, says to use it “within the timeframe specified by your pharmacy”, and there is no current label to check. Ask the pharmacy that dispensed it.
What if my sermorelin arrives warm?
One seller, Vytora Health, says melted ice packs are normal and gives stability figures with no source; it also says warm arrival usually doesn’t qualify for a refund. No other page we hold addresses it. The dispensing pharmacy is the one to ask whether a warm vial is usable.
Do sellers ship sermorelin cold?
On 6 of 88 pages the seller says it does. The other 82 don’t say whether it travels cold.
