Storage & handling.

Keep sealed vials refrigerated (2–8°C) or frozen (−20°C) until you're ready to use them. Keep them dry and protected from direct light.

Bring the vial to room temperature before opening to reduce condensation on the seal.

Once mixed, store the vial refrigerated at 2–8°C. Follow any specific handling note printed on the product page — some peptides are best used within days, others tolerate several weeks refrigerated.

Swirl gently to mix. Do not shake vigorously.

Keep vials out of direct sunlight and away from heat sources. Repeated warming and cooling reduces stability faster than a single, steady storage temperature.

Where longer storage is needed, small single-use aliquots can be frozen once. Repeated freeze/thaw cycles should be avoided.

Lyophilised peptides are stable during short transit at ambient temperatures. Refrigerate promptly on arrival. If a parcel is delayed or arrives visibly compromised, contact us.
