Our standard

The peptide industry has a transparency problem.

We built Pure Science for researchers who want a supply chain they can actually verify — not marketing copy and unverified purity claims.

Most suppliers

“Trust us, it’s 99% pure.”

  • No third-party testing
  • No batch-level documentation
  • Unknown synthesis origin
  • No cold-chain handling
Pure Science — the new standard

“Here’s the COA. Verify it yourself.”

  • Independent HPLC + LC-MS, every batch
  • Public certificate of analysis per vial
  • Operated, tested & shipped from the USA
  • Insulated, temperature-controlled shipping

Common questions

Everything researchers ask before ordering.

Where do you operate and ship from?

Pure Science is a US-based operation. Our compounds are globally sourced and independently third-party tested, and every order ships from the USA with full tracking. Orders placed before 4pm EST ship the same business day.

How is purity verified?

Every batch is tested by an independent lab using HPLC for purity and LC-MS for identity. The COA is stamped with the batch number, test date, and lab name, and uploaded to the product page before any vial from that lot ships.

What documentation comes with my order?

Every vial ships with a tamper-evident seal and a packing slip referencing the batch ID. The matching certificate of analysis is available on the product page and in your account downloads.

How fast do orders ship?

Orders placed before 4pm EST ship the same business day. Standard delivery is 2–4 business days. Free US shipping on orders over $250.

No. All products on this site are sold for laboratory research use only. They are not intended to diagnose, treat, cure, or prevent any disease, and are not for human or veterinary consumption. By purchasing you confirm you are a qualified researcher.
