Where I source for my own routine.
I get asked all the time where I get my peptides. The honest answer: American Peptides— a U.S.-based supplier with third-party-tested research products and transparent sourcing. I've partnered with them to give my community partner pricing through a single link.
AMERICAN PEPTIDES · KATHRYN'S CODE
Peptides are an unregulated space. I only point my community to a brand I'd trust myself — sourced in the U.S., third-party verified, and transparent about how every batch is tested.

“If I wouldn't use it myself, I won't put my name on it.”
— Kathryn Watkiss
Shop the brand I trust — at partner pricing, through my link.
I've seen too many people buy from sketchy, unverified suppliers and end up with junk. American Peptides is the only source I personally use, and the only one I'll point my community to. When you shop through my link, you get partner pricing — and I get a small commission at no extra cost to you.
