Frequently Asked Questions
What purity level are your peptides and how is it verified?
Our peptides maintain a research-grade purity level of >99%. Each batch is rigorously verified using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to ensure precise chemical composition and identity.
What is a Certificate of Analysis (CoA) and how do I read it?
A CoA is a document providing the specific test results of a batch. It includes the HPLC chromatogram (purity), Mass Spec (molecular weight confirmation), and appearance. It ensures that the product you receive meets all stated specifications. Every batch CoA is publicly available on our COA library before purchase.
Do you test every batch independently?
Yes. Every single batch is tested by an independent third-party laboratory before it is made available for purchase. We never self-certify. If a batch does not pass independent testing, it does not get listed — period.
How should I store peptides before reconstitution?
Lyophilized (freeze-dried) peptides should be stored in a cool, dry place away from light. For long-term storage, a refrigerator (2–8°C) or freezer (-20°C) is recommended to maintain maximum stability for up to 24 months.
Are your peptides lyophilized?
Yes. All peptides ship in lyophilized (freeze-dried) form for maximum stability and shelf life. They must be reconstituted with bacteriostatic water before use in research applications.
What is the shelf life of your peptides?
Lyophilized peptides stored refrigerated (2–8°C) or in a freezer (-20°C) have a shelf life of 24+ months. Once reconstituted with bacteriostatic water, the solution should typically be used within 28 days and kept refrigerated.
How much bacteriostatic water do I need?
The volume of BAC water depends on the desired concentration for your research protocol. As a general starting point, 1–2mL of BAC water per vial is common, but this varies by compound and application. We offer BAC water in 10mL and 30mL sizes.
How fast do you ship and is cold shipping included?
Most orders ship same-day or within 24 hours. All orders ship with cold packs to maintain peptide stability during transit. Lyophilized peptides are highly stable at room temperature, but the cold pack adds an extra layer of protection — especially for temperature-sensitive compounds and warm-weather shipping.
How do I track my order?
Once your order ships, you will receive a tracking number by email. You can also log into your account and view your order details and tracking information at any time.
What payment methods do you accept?
We accept major credit cards, debit cards, and other secure payment methods at checkout. All transactions are processed through a secure, encrypted payment gateway.
Do you ship internationally?
Yes, we ship to most countries worldwide. Please check your local regulations regarding the import of research peptides. Shipping times and costs vary depending on the destination.
Do you offer bulk pricing?
Yes. We offer tiered bulk discounts automatically applied at checkout (10% off 3+, 15% off 5+, 20% off 10+). For institutional or large-volume orders beyond these tiers, contact our team directly to discuss pricing.
Are these peptides for human use?
No. All products sold are strictly for laboratory research and professional use only. They are not intended for human consumption, diagnostic, or therapeutic use.
What is your return and refund policy?
Due to the nature of our products, we cannot accept returns once a shipment has been opened or the seal broken. However, if there is an issue with product quality or shipping, please contact us within 14 days for a replacement or resolution.
