Peptide Storage Guide

Storing peptides properly is essential to preserve their integrity, potency, and research value. This friendly, clear guide gives you the exact steps to do it right

Key Factors That Affect Storage

🧪 Temperature

📦 Container quality

💧 Moisture control

🔆 Exposure to light

Ideal Storage Conditions

1. Store peptides cold
   • Long-Term: Freeze lyophilized powder at -20°C (-4°F) or colder. After reconstituting, avoid freezing
   • Short-Term (Days to Weeks): Store at 2°C to 8°C (36°F to 46°F).
2. Store peptides dry
   • Avoid moist, humid environments
   • If lyophilized powder becomes pasty, discard immediately
3. Store peptides in the dark
   • Avoid direct sunlight or harsh lighting.
   • Storing in a dark place is optimal
4. Store peptides in the right containers
   • Use airtight, sterile vials.
   • Glass or high-quality plastic with secure lids recommended.
   • Honest Peptide uses airtight, glass vials with secure, inert rubber lids

Quick Tips for Storing Peptides

Label everything: Include name, date, concentration, solvent type
Minimize freeze-thaw cycles: Aliquot into smaller vials
Thaw gently: Let peptides return to room temperature slowly
Don’t leave out: Return peptides to cold storage immediately after use

Frequently Asked Questions (FAQs)

• Can I store peptides in my fridge or freezer?

A freezer is ideal for long-term storage of lyophilized powder due to stable low temperature and minimal moisture. Just remember to:

1. Never store reconstituted solution in freezer
2. Separate peptide vials for other contaminants (e.g., place in a small zip lock)

A fridge is ideal for short-term storage of reconstituted solution due to stable, cool temperature and minimal moisture

• How long do peptides last in storage?
  • Frozen: Up to a year or longer
  • Refrigerated
• What happens if moisture gets in?
  • Moisture can degrade peptides or introduce contamination.
• 😬 Can peptides go bad from light exposure?
  • Yes. UV and strong indoor light can break down sensitive peptides.
• 🔁 What’s wrong with freeze-thawing repeatedly?
  • Causes peptide degradation. Always aliquot into single-use portions if possible.
• 👨‍🔬 Are peptides safe for human use?
  • 🚫 No. These products are strictly for laboratory research only, not for human or animal consumption or application.
• 🧪 Final Tip: Consistent, careful storage keeps your peptides pure and effective for the long haul!
