⚠️
Avoid
Harmful to Peptides
Direct sunlight · Moisture
Repeated freeze-thaw
01
Temperature range: Best kept at −20 °C for long-term storage, or 2–8 °C if used within a short window.
02
Zero moisture: Moisture degrades peptide powder faster than almost anything else — leave the original packaging sealed until the moment of use.
03
Block out light: Keep vials inside their original packaging or an opaque container at all times.
04
Warm up first: Let the vial reach room temperature and let any condensation clear before piercing the stopper.
01
Use a sterile solvent: Reconstitute exclusively with a sterile solvent suitable for your protocol — never tap water or plain distilled water.
02
Straight to the fridge (2–8 °C): Once dissolved, a peptide belongs in the refrigerator. Typical shelf life: 14–28 days.
03
Note the date: Write the reconstitution date on the vial so shelf life stays trackable.
04
Freezing is off-limits: A frozen-then-thawed peptide loses its structure — reconstituted solutions must never be frozen.
Best Practices
6 Essential Storage Tips
🧴
Use a sterile solvent
A sterile, appropriate solvent keeps bacterial growth in check and meaningfully extends post-reconstitution shelf life.
🩺
Disinfect before every draw
A fresh alcohol swab on the septum before each withdrawal prevents contamination across multiple uses from the same vial.
🌡️
Keep the temperature constant
Fluctuating temperatures shorten shelf life dramatically — the target range needs to stay steady, not just be hit occasionally.
🌑
Shield it from light
Many peptides degrade under UV exposure — original packaging or an opaque container solves this by default.
❄️
One freeze-thaw cycle, never more
Every freeze-thaw cycle damages the peptide structure. Freezing only makes sense for powder that has not yet been dissolved.
📅
Write the date, every time
A reconstitution date on the vial keeps shelf life and batch order visible at a glance.
Frequently Asked Questions about Storage
Yes — lyophilised powder tolerates −20 °C without issue. Just let any condensation clear after thawing, before opening the vial.
Typically 14–28 days refrigerated at 2–8 °C, depending on the specific peptide and the purity of the water used.
A sterile solvent suitable for your protocol — never tap water, never plain distilled water.
Yes — many peptides are light-sensitive and break down under UV. Original packaging or an opaque container avoids this entirely.
A few hours at room temperature is generally tolerable. Extended heat exposure or temperatures above 30 °C, however, noticeably speed up degradation.
