StarBio is a United States supplier based in Florida. Every order ships from Florida to addresses in all 50 states; we don’t ship internationally. Shipping details.

Independent third-party laboratories: Janoshik Analytical and Medutest. Testing isn’t done by StarBio or by our suppliers. Each report covers a specific batch and is published on the product page and in the COA library, and Janoshik Analytical reports can be checked on janoshik.com by their report number. How we test.

Yes. Every compound is sold for in vitro laboratory research by qualified researchers aged 21 or older. Nothing we sell is for human or veterinary use, and we don’t give advice on doses, protocols or uses.

Browse the catalog, add compounds to your cart and check out. At checkout you confirm that the order is for laboratory research and that you are 21 or older. Ordering while signed in keeps your order history and tracking in one place, and every order earns points.

Cards, Apple Pay, Google Pay and Klarna, plus payment by app or bank transfer (such as Zelle or Cash App). The options available for your order are shown at checkout.

Email support as soon as possible with your order number. If the order hasn’t shipped yet, we’ll see what we can do. Once it has shipped it can’t be changed, and delivered products can’t be returned (see Returns & Refunds).

Qualified researchers and institutions aged 21 or older, buying for in vitro laboratory work. Everything we sell is for research use only: not for human or veterinary use, and not for diagnostic or therapeutic purposes. The full conditions are in our Terms of Service.

For larger or recurring orders, send us the compounds and quantities you need and we’ll reply with options.

We ship within the United States only, to all 50 states. Standard is $4.99, Two Day is $14.99 and Overnight is $39.99, and standard shipping is free on orders over $100. Full details are on the shipping page.

Most orders leave within one to two business days (Monday to Friday, excluding US federal holidays). Each product page shows a live countdown to the next dispatch cutoff.

Compounds ship as sealed, lyophilized powder, which stays stable at room temperature in transit. Vials are cushioned inside a rigid outer box, and a cold pack is added where a compound calls for one. Every order is photographed at fulfillment.

The tracking number is emailed as soon as the label is created. You can also look up any order on the Track My Order page, or sign in to see all of your orders.

Shipment protection is included on every order at no extra cost. Photograph the vial, packaging and label, then email [email protected] with your order number within 14 days of delivery. A parcel whose tracking shows no movement for 10 business days counts as lost. Approved claims get a replacement with fresh tracking. How claims work.

Keep sealed lyophilized powder cold and dark: 2–8°C for shorter periods, or −20°C for long-term storage. Let a cold vial reach room temperature before opening it, or condensation forms on the powder. Once reconstituted, keep it refrigerated and avoid repeated freeze-thaw cycles. Each product page lists its own conditions, and our storage guide covers the details.

Water with 0.9% benzyl alcohol added as a preservative, for reconstituting lyophilized research compounds. It’s listed under research supplies, so you can add it to the same order.

We’re happy to answer questions about specifications, documentation, storage and availability. We don’t advise on protocols, doses or uses, and requests for that kind of guidance are declined.

Yes. Compounds are analysed by independent laboratories (Janoshik Analytical and Medutest), and the report is published on each product page and in the COA library. See our quality standards.

Every product page shows its Certificate of Analysis under the description, and all reports are in the COA library. Certificates aren’t printed in the box and our labels don’t carry a lot number, so if you need the certificate for a specific order, send your order number through the COA request form.

HPLC purity is a relative area percentage: the main peak measured against every other peak the detector sees. It isn’t the same as peptide content by weight, because lyophilized material also carries water and counter-ions that don’t appear in that calculation. Where a report measures content, it’s shown as milligrams found against the labelled amount. More on purity testing.

HPLC measures purity, and mass spectrometry confirms identity by comparing the measured molecular weight with the value expected from the sequence. The two answer different questions, which is why a credible report includes both. Our guide explains how to read a certificate.

Every account earns 2.5 to 10 points per dollar spent on products, depending on tier. Points are credited when the order ships, and 100 points take $1 off a future order. Points don’t expire. You also get 100 points for creating an account, 250 for adding a phone number and 150 for reviewing a compound you bought. Rewards details.

Paid plans raise your points rate and add free shipping, with more perks on higher plans. Each plan is billed once for twelve months and doesn’t renew automatically. Compare plans.

Yes. Approved partners earn commission when researchers they refer place orders. Learn about the partner program.
