The questions researchers ask before ordering: with straight answers
Where we hold a third-party COA for a product, it is linked on the product page as a downloadable PDF. For products marked COA pending, previous lots, or custom documentation needs, submit a support ticket with the lot number and we'll provide the documentation within one business day.
Unreconstituted peptides: store at -20°C for long-term (up to 24 months) or 2–8°C for short-term (up to 3 months). Reconstituted peptides: always store at 2–8°C and use within 30 days. Avoid repeated freeze-thaw cycles as this degrades the peptide.

Use bacteriostatic water (BAC water) for reconstitution. Draw the appropriate volume into a syringe and inject slowly down the inside wall of the vial.
