Reconstitution FAQs
9 questions answered
Can you mix multiple peptides in the same vial?
Mixing peptides in the same vial is generally not recommended due to potential chemical interactions between different amino acid charges, pH incompat...
How does water volume affect peptide dose accuracy?
The volume of bacteriostatic water added directly determines the concentration of your peptide solution, which impacts dosing precision. Using too lit...
Can you freeze reconstituted peptides?
Reconstituted peptides can be frozen at -20°C to -80°C, but repeated freeze-thaw cycles significantly degrade peptide quality and should be avoided. F...
What temperature should peptides be stored at?
Lyophilized (freeze-dried) peptides should be stored at -20°C to -80°C for long-term stability, though they can remain stable at room temperature for...
How can you tell if a reconstituted peptide has gone bad?
Signs of peptide degradation include visible changes such as cloudiness, turbidity, floating particles, or precipitate formation in a solution that wa...
How long do reconstituted peptides last in the refrigerator?
Reconstituted peptides typically remain stable for 2-4 weeks when refrigerated at 2-8°C (36-46°F), though some sources indicate stability up to 6-8 we...
How do you calculate peptide concentration after reconstitution?
The concentration formula is: Peptide Mass (mg) divided by Volume of Solvent (mL) equals Concentration (mg/mL). For example, reconstituting a 5mg pept...
How do you properly reconstitute lyophilized peptides?
Allow both the peptide vial and solvent to reach room temperature for 30 minutes, then sanitize the vial stopper with an alcohol swab. Insert a needle...
What is the difference between bacteriostatic water and sterile water for peptide reconstitution?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative that inhibits bacterial growth, allowing the solution to be used for up to 28 days...
