Can you tell me how to use a product?

No. Everything we sell is for laboratory research use only, and our team can’t provide usage, dosing, or application guidance of any kind.

Do you offer discounts?

Yes! We offer discounts all the time! In order to get them, you'll need to subscribe to our email newsletter.

How fast will I hear back?

Within one business day in almost every case. Messages sent over the weekend are answered the next business morning.

The website isn’t working. Who do I tell?

Use the contact form and pick “Website issue,” or email us a quick screenshot. Details like your browser and what you were doing help us fix it faster.

Do you offer free shipping?

Yes, once your order total reaches $299, we automatically apply free shipping to every order.

How long have you been in business?

We've been here far longer than most. RCS Research has served the research community since 2018, long before peptides became a mainstream buzzword, and long before the flood of pop-up companies rushing to ride the peptide wave.

Do you have CoA testing available?

Yes! They can be found on individual product pages, as well as our CoA page.

Still have a question?
