FAQ
Still need help?
Find answers to common questions about our peptides, shipping, testing, and support.
What are peptides?
Peptides are short chains of amino acids — typically between 2 and 50 — linked by peptide bonds. They play essential roles in biological processes and are widely used in scientific research to study cellular signaling, receptor binding, and metabolic pathways.
How much bacteriostatic water should I use to reconstitute?
The amount depends on the peptide and desired concentration. A common approach is to add 1–2 mL of bacteriostatic water per vial. Use an online peptide reconstitution calculator for precise dosing based on the peptide's total content in milligrams.
How do I reconstitute my peptides?
Using a sterile syringe, slowly inject bacteriostatic water into the vial along the glass wall — never directly onto the lyophilized powder. Gently swirl (do not shake) until the powder is fully dissolved. The solution should be clear with no visible particles.
How long do peptides last?
Lyophilized (freeze-dried) peptides can remain stable for 12–24 months when stored properly at -20°C. Once reconstituted with bacteriostatic water, most peptides remain viable for 4–6 weeks when refrigerated at 2–8°C.
How should I store my peptides?
Store lyophilized peptides in a cool, dry, dark place — ideally in a freezer at -20°C. Reconstituted peptides should be kept refrigerated at 2–8°C. Avoid repeated freeze-thaw cycles and exposure to direct sunlight or heat.
What is the recommended approach for research dosing?
Dosing varies by compound and research protocol. Always refer to published literature for the specific peptide you are working with. Start with the lowest effective concentration and titrate based on your experimental objectives.
