Most mistakes happen during mixing and storage after reconstitution.
Understanding these two steps first will help preserve peptide stability and avoid unnecessary degradation.
1. How to Mix (Reconstitute) Peptides — The Most Important Step
Mixing peptides incorrectly can damage them immediately.
What you need:
• Bacteriostatic water (BAC water)
• Sterile syringe
• Alcohol swab
Simple steps:
• Clean the vial top with alcohol
• Slowly add the liquid along the inside wall of the vial
• Gently rotate the vial — never shake
• Wait until the powder fully dissolves
Gentle handling helps preserve the peptide structure.
2. How to Store Peptides After Mixing (Refrigerator)
Once a peptide is mixed, proper storage becomes essential.
After reconstitution:
• Store in the refrigerator (2–8°C)
• Keep protected from light
• Use within 30 days
• Avoid repeated temperature changes
• Do not expose mixed peptides to heat
3. What Liquid to Use for Mixing
Peptides are commonly mixed with bacteriostatic water (BAC water).
Why BAC water?
• Helps prevent bacterial growth
• Supports stability after mixing
• Allows short-term refrigerated storage
Avoid using non-sterile liquids.
4. Storing Peptides Before Mixing (Powder Form)
Before mixing, peptides are usually in dry (lyophilized) form.
Best practices:
• Store in a cool, dry place
• Protect from light and humidity
• Keep the vial tightly sealed
5. Simple Safety Rules
• Always use sterile syringes
• Label vials with the mixing date
• Avoid exposure to heat
• Handle everything with clean hands
Final Note
Correct reconstitution and proper refrigerated storage are the two most important factors when handling research peptides. By following these basic guidelines and maintaining clean handling practices, peptides can remain stable and reliable throughout their intended research use.
Each production batch is independently tested by accredited third-party laboratories to confirm purity and molecular integrity.
We are proud to support laboratories and research professionals who prioritize quality and consistency.
Yes. Every batch undergoes independent third-party laboratory testing to verify purity, identity, and molecular integrity. A Certificate of Analysis (COA) is provided for transparency, including HPLC and mass spectrometry data. We are committed to delivering consistently verified research materials.
No. All products sold on our website are strictly intended for laboratory research purposes only. They are not approved for human consumption, medical use, or therapeutic application. By purchasing, customers confirm they are qualified professionals conducting authorized research.
Peptides should be stored in a cool, dry environment away from direct sunlight. For long-term stability, refrigeration is recommended. Once reconstituted (for laboratory use), peptides should be handled according to proper research protocols to maintain molecular integrity.
Yes. We provide batch-specific Certificates of Analysis (COA) for full transparency. Each report includes purity percentage, analytical testing results, and batch verification details. Customers can download reports directly from our website or verify using the batch number.
