Sermorelin can lose potency if not stored as directed, so refrigerate it and follow the pharmacy label.
Storage
Sermorelin is a prescription peptide. Unmixed (lyophilized) vials are often stored refrigerated at 36 to 46°F (2 to 8°C). After mixing, it must be refrigerated.
If left out
Heat can break down the peptide and reduce potency.
What to do
Follow your pharmacy’s label. Ask the pharmacist if a vial was out of the fridge.
Don’t
Freeze it.
Travel
Use a cooler with an ice pack.
Prescriber
Take only under medical supervision.
What the label says
Sermorelin is a prescription peptide, an analog of growth hormone-releasing hormone, available through compounding pharmacies in many cases because the original branded product (Geref) was discontinued in 2008 for business reasons. Compounded sermorelin is usually stored refrigerated at 2 to 8 C (36 to 46 F) after mixing and sometimes before.
- Peptide solutions can degrade at room temperature, losing potency over hours to days, depending on formulation.
- Follow the instructions from the pharmacy, since storage varies by product, such as lyophilized powder versus mixed solution.
- Mixed vials generally last about 2 to 4 weeks in the fridge, depending on the pharmacy’s beyond-use date.
If it was left out
Contact the prescribing clinic or compounding pharmacy to ask if it is still usable, and report how long and at what temperature. Do not use a product that looks cloudy, has particles or changed color. Do not freeze unless told. For travel, use an insulated cooler with ice packs. FDA has not approved compounded versions, and quality varies, so choose a licensed pharmacy.
What the label says
Sermorelin is a peptide that stimulates growth hormone release. Compounded vials are often stored refrigerated at 2 to 8 C. Peptides can degrade at room temperature.
If it was left out
Check the label and ask the pharmacist. Do not use if it looks cloudy. The FDA does not approve compounded sermorelin for general anti aging use.
Storage rules for the peptide
Sermorelin is a growth hormone releasing hormone analog sold as a powder or compounded solution. Unreconstituted powder is usually stored in a refrigerator at 36 to 46 degrees Fahrenheit (2 to 8 Celsius), and reconstituted vials must be kept refrigerated and used within about 14 to 30 days, as the pharmacy directs. Always follow the label.
If it was left out
Peptides can degrade with heat, which lowers potency, though short periods at room temperature may not destroy it. Cloudiness, particles or discoloration mean it should not be used. Ask the dispensing pharmacist about stability data for the specific product. Do not freeze it. Sermorelin was withdrawn as a brand product (Geref) in the US in 2008 for business reasons, and compounded versions are available by prescription, so only use licensed pharmacies and medical supervision.
