About Acu Aminos

Precision amino solutions, proven product by product.

Acu Aminos is an Arizona-based supplier of research-grade peptides for laboratory and in-vitro use. We built the company around a single rule: every product we sell has a published Certificate of Analysis a researcher can pull up in seconds.

The Acu Aminos standard

A supplier should prove its purity, not just print it on the label.

Most research-peptide listings lead with a purity number and stop there. Where did the number come from, which product does it belong to, and can you check it yourself? Too often the answer is a stock photo of a chromatogram and a promise. That gap is what Acu Aminos was created to close.

Every product we sell is tied to its own analytical report, published to our COA library and linked from the product page. That one requirement shapes every other decision we make, from the synthesis partners we work with to how a vial is sealed, stored and shipped.

Release process

What happens before a product is allowed to ship

The same four gates for every product in the catalog, whether it is a $6 vial of bacteriostatic water or a 40 mg incretin peptide.

  1. 01

    Solid-phase synthesis

    Each peptide is built residue by residue on resin, cleaved, and purified by preparative reverse-phase HPLC to a minimum 99% target before it is lyophilized.

  2. 02

    HPLC and mass-spec testing

    Analytical HPLC establishes purity and mass spectrometry confirms the sequence mass. Material that misses specification is rejected outright; we do not sell it as a second grade.

  3. 03

    COA published first

    The report is uploaded to the COA library and linked from the product page, where anyone can open it before ordering. Only then is the product released to inventory.

  4. 04

    Sealed and shipped in one day

    Lyophilized powder in sterile glass, stored in a climate-controlled facility and shipped at ambient temperature within one business day of your order.

Beyond the purity number

Quality is the whole chain of custody, not a single percentage.

Two vials can both read 99% pure and still behave differently on the bench because of net peptide content, counter-ion, residual moisture or how they were stored. We track those variables and state them on the COA, so the material you dissolve matches the material we tested.

  • Sequence identity confirmed by mass spectrometry
  • Net peptide content and counter-ion stated on the COA
  • Climate-controlled storage, sealed glass, tamper-evident caps
  • Every product traceable to its analytical report
  • Chemistry-only product pages, written from the primary literature
Our boundaries

Built for laboratories, and only laboratories

Acu Aminos supplies reference-grade reagents to researchers. We are not a pharmacy, a clinic, a compounder or a supplement brand, and we will not tell you how to dose, reconstitute or administer anything, because our products are not intended for human or veterinary use.

Every customer verifies they are 21 or older and confirms a research purpose at checkout. Holding that line is what lets us keep publishing full analytical data instead of hiding behind vague marketing.

What you can count on

Four promises, printed on every order

A COA for every product

Published in the COA library and linked from every product page. Open it before you order, or any time after.

30-day satisfaction guarantee

If a product misses its published specification, we replace it or refund it, no forms required.

Real people, one business day

Arizona-based support by email. Product, COA and order questions answered by someone who knows the catalog.

Strict research-use policy

21+ verification, a research acknowledgement on every order, and product pages that stick to chemistry.
