What is Matrixyl?
Matrixyl (Palmitoyl Pentapeptide-4) is a matrikine / collagen-stimulating peptide. Palmitoyl-Lys-Thr-Thr-Lys-Ser pentapeptide; mimics collagen breakdown fragments (matrikines) to upregulate collagen I, III, fibronectin, and hyaluronic acid synthesis via TGF-β pathway activation. Research use only.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
