About Us

VialCove specializes in a comprehensive range of research-grade peptides, with operations spanning research, production, and distribution.

Research, production and distribution

Our research team brings together researchers from Israeli universities, supported by an established laboratory team in Israel. We organize production through our extensive manufacturing network in China, then ship finished products to our U.S. warehouse for local storage and fulfillment.

Our goal is to combine advanced research capabilities, efficient production, and competitively priced shipping to serve suppliers, institutions, and research teams around the world.

Documentation you can review

Every batch comes with an up-to-date Certificate of Analysis (COA). Our testing documentation includes reports from Vanguard Laboratory in the United States and other testing laboratories. Our partners can review the relevant analytical results alongside product specifications whenever they need them.

A dedicated account team

Our dedicated account team handles product inquiries, quotations, and order follow-up. Once you place an order, we begin tracking its progress through warehouse processing, packing, and shipping. We stay involved through delivery and help resolve any issues along the way.

A little more clarity

Before you
begin.

The answers worth knowing
before you make a selection.

How do I choose a specification?

Compare the amount per vial and the number of vials in the pack. Open a product and select an available option to see its image and price.

Does the price change with the specification?

Yes. Each specification has its own price. The collection shows the first available option in the store’s product order, and your bag uses the option you select.

What should I check on a report?

Check the sample name, specification, batch identifier, report date and issuing laboratory. A report for another supplier or batch does not verify your selected product.

Where can I find product documentation?

Preview the selected documents in our COA section or open the full report library. Each document includes its own source and sample details.

Where are delivery options shown?

Delivery options and charges are shown at checkout for your destination. Check the available details before placing your order.

How can I review my bag?

Open your bag to review the products, specifications, quantities and current prices you selected. You can make changes before continuing to checkout.
