Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial, directing liquid down the inner wall. Swirl gently until dissolved. Solution should appear clear. Liraglutide’s fatty acid tail makes it slightly slower to dissolve than shorter peptides — allow 5–10 minutes.
How should this peptide be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 28 days. Liraglutide’s albumin-binding C16 fatty acid modification provides some stability, but avoid freezing reconstituted solution and minimize light exposure.
What purity is this QSC compound and how is it verified?
QSC Liraglutide is ≥99% pure by HPLC on every batch, with MS confirmation of molecular weight. COA is published on the product page and verifiable via Janoshik at verify.janoshik.com.
