Leave stock in its original packaging
Keep vials unopened in their cartons until needed. Avoid bright light, humidity and unnecessary exposure to room air.
WHOLESALE PEPTIDE STORAGE & DELIVERY
How to store peptides.
Practical guidance for reseller stock.
Practical storage guidance for international peptide resellers: how to keep sealed vials, how long to hold stock and which cold-storage equipment fits your inventory and local deliveries.
TEMPERATURE & STORAGE TIME
How long can I store sealed lyophilized peptides?
Our reference guidance for unopened, dry peptide vials. Keep the original seal intact and protect the stock from light and moisture.
| Temperature | When to use it | Reference storage time |
|---|---|---|
| 15–25°C | Short-term holding or transit, away from heat and direct sunlight. | A few weeks to a few months |
| 2–8°C | Refrigerated inventory for regular reseller stock turnover. | About 1 year |
| −20°C | Longer-term reserve stock, kept sealed and protected from moisture. | About 2 years |
These are our reference storage periods, not the storage time for reconstituted solutions. Follow the product’s batch label if it states a shorter period or different conditions. Refrigerating stock does not restart its shelf life.
EVERYDAY PEPTIDE STORAGE
Keep it sealed. Keep it cold. Keep it dry.
Use a fan-cooled pharmacy refrigerator
For 2–8°C stock, we recommend a dedicated, fan-cooled unit with a suitable defrost function. Leave space around cartons and keep air outlets clear.
Take out only the stock you need
Keep the rest of the inventory in cold storage. Avoid repeatedly moving the same vials between cold and warm conditions.
Keep a cold, dry vial sealed while it warms
If a dry vial needs to be opened for laboratory work, let it reach room temperature while still sealed to reduce condensation on the powder.
EQUIPMENT FOR RESELLER INVENTORY
Three equipment types. Three everyday uses.
Start with how much stock you hold and whether it stays on a shelf or goes out for delivery.
Small reseller inventories
Compact pharmacy refrigerator
For resellers holding a few boxes to a few dozen. A compact, dedicated unit provides a separate space for day-to-day peptide inventory and regular replenishment.
Larger, multi-product inventories
Large air-cooled pharmacy refrigerator
For larger resellers managing more boxes, several products and separate batches. Use the shelving to organize stock and leave space around cartons for airflow.
Delivery to downstream customers
Portable medical cooler
For moving small orders between storage locations or handing them over to customers. Match the verified temperature range and operating time to the delivery conditions.
Equipment examples only. Match the unit to the product’s documented storage temperature; confirm capacity, alarms and transport runtime with the equipment manufacturer.
RESELLER STOCK PLANNING
Keep stock cold from arrival to your next dispatch.
Plan your receiving space before an international order arrives. Keep local selling stock ready for regular dispatch, with longer-term reserves stored separately.
- Move received cartons into the product’s specified cold storage.
- Keep packaging sealed, dry and protected from light.
- Pick only the cartons needed for the next customer order.
- Use suitable portable cold storage when delivery requires temperature control.
AFTER RECONSTITUTION
Allow 15–30 minutes before laboratory use.
When taking a reconstituted vial out of the refrigerator for immediate laboratory use, allow it to stand for 15–30 minutes, following its specific handling instructions.
Use reconstituted material promptly. Keep the rest of your resale inventory unopened, and do not use the dry powder’s storage period for a prepared solution.
Research-material handling only. Not instructions for injection, dosing or human use.
RETATRUTIDE / RETA INVENTORY
How to store Retatrutide before reconstitution.
Buying Reta for resale? Keep the powder in its original sealed vial, away from light and moisture. Use the storage conditions stated for the product you are ordering.
Choose the vial specification and quantity around your expected sales and available cold storage. Keep routine stock separate from reserve cartons, and leave vials unreconstituted until needed for laboratory work.

RESELLER STORAGE QUESTIONS
Quick answers for your inventory.
How long can sealed lyophilized peptides stay at room temperature?
Our reference guidance is a few weeks to a few months at 15–25°C for sealed, dry vials protected from heat, light and moisture. Use room temperature for short-term holding or transit rather than routine long-term inventory. Follow any shorter period or different condition on the product’s batch label.
How long can I store peptide stock in the refrigerator?
Our reference period for sealed lyophilized stock at 2–8°C is about 1 year. This does not apply to reconstituted solutions. Follow the product’s batch label if it gives a shorter period or different storage conditions.
Which refrigerator do you recommend for peptide reseller inventory?
We recommend a dedicated, fan-cooled pharmacy refrigerator for 2–8°C stock, with a suitable defrost function and a temperature display or alarm. Choose a compact unit for a few boxes to a few dozen, or a larger cabinet for multiple products and batches. Keep cartons clear of the air outlets.
How should Retatrutide (Reta) powder be stored before reconstitution?
Keep Retatrutide powder in its original sealed vial, protected from light and moisture. For reseller inventory, use the product’s stated refrigerated or frozen storage conditions and leave stock unreconstituted until it is needed for laboratory work. The reference periods on this page are for sealed dry stock, not Reta solutions or pens.
What should I do after taking a reconstituted peptide out of the refrigerator?
For immediate laboratory use, take out only the vial needed and allow it to stand for 15–30 minutes before use, following the product’s specific handling instructions. Use reconstituted material promptly; do not apply the unopened powder’s storage period to the prepared solution.
How much stock should a small peptide reseller keep?
Plan around your expected sales rather than the maximum storage period. For a few boxes to a few dozen, a 1–3-month sell-through plan helps you choose an order size and replenishment schedule. Keep reserve stock separate and use the batch with the earliest applicable expiry first.
PLAN YOUR NEXT RESTOCK
Plan storage with your next supply request.
Send the products, vial sizes, number of boxes and destination. Tell us whether you have a 2–8°C refrigerator or frozen storage so we can discuss your stock plan and quotation.
