Question 1

What is the purity of your peptides?

Accepted Answer

Our research peptides are independently tested by HPLC and mass spectrometry, and most are verified at 99%+ purity — the exact figure for each compound is listed on its product page. Diluents such as bacteriostatic water are USP grade rather than a purity percentage.

Question 2

How fast do orders ship?

Accepted Answer

Most US orders ship within 1 to 3 business days from our domestic facility, in plain, unmarked packaging.

Question 3

Are these products for human use?

Accepted Answer

No. All compounds are sold strictly for in-vitro research and educational purposes. They are not intended for human or veterinary use.

Question 4

Can I see the Certificate of Analysis (COA)?

Accepted Answer

Yes. Our third-party tested COAs are published publicly — no request or account required. Browse the archive at /coa or use the COA link on the product page. If a COA is not yet posted for a SKU, email support@optimized-aminos.com and we will send it.
