Frequently Asked Questions
Everything you need to know about research use, purity, reconstitution and dispatch.
Research & compliance
Are LYSENTA’s peptides intended for human use?
No. All products are intended solely for laboratory and research purposes. They are not intended for human or animal consumption, are not medicinal products and do not constitute medical advice.
Do you provide dosage advice?
No. We do not provide dosage advice or make health claims. On product pages, we describe only the research context, mechanisms and technical specifications.
What does ‘research use only’ mean?
This means that the product may only be used within a controlled laboratory or research environment by qualified personnel, and not for consumption or therapeutic purposes.
Quality & documentation
How is purity determined?
Each batch is tested using HPLC (High-Performance Liquid Chromatography) and mass spectrometry. Our threshold is ≥99% purity.
What is a Certificate of Analysis (COA)?
An independent laboratory certificate from Janoshik Analytical confirming the purity and identity of a specific batch. The COA is linked to the batch number on the label.
Can I see the laboratory certificate?
Yes. Where available, the COA is linked to the product and can be downloaded. The batch ID on the vial label refers to the corresponding certificate.
Reconstitution & storage
How do I reconstitute a lyophilised peptide?
Use bacteriostatic water from our Lab & Accessories range. Add the liquid slowly down the side of the vial. The exact ratio is specified in the instructions for use for each product.
How do I store peptides?
Lyophilisates should be stored at -20 °C for long-term storage. After reconstitution, store at 2–8 °C and generally use within 30 days.
What equipment do I need?
Bacteriostatic water, insulin syringes and alcohol wipes — all available in the Lab & Accessories category.
Shipping & delivery
Where does LYSENTA ship from?
Our factory is in China. We ship to supported destinations worldwide, normally within 48 hours after order and payment confirmation. Delivery time depends on the destination and carrier.
How are orders packed?
Orders use protective, multi-layer bubble wrap and discreet packaging, with tracking and the relevant batch documentation.
In which currency should I pay?
All product prices are displayed in whole US dollars (USD). Payment is arranged through the confirmed order quotation or the seller's verified Alibaba.com transaction. Available card, debit-card or wallet methods are those shown for that transaction.
