Where to buy — our verified sources

This is not a comprehensive vendor directory. It's a short list of sources we've personally vetted. Here's the deal, stated plainly:

When you use my coupon code to buy peptides with these sellers, you enjoy a discount off retail price, and I make a small commission which helps me to continue to offer this peptide educational site to you for free. I only have affiliate relationships with peptide manufacturers that show evidence that their peptides are 100% manufactured in the US, 3rd party lab tested for purity, transparent COAs posted on their websites, and that have good customer service.

① These are affiliate partnerships

Every vendor below gives us an affiliate link or coupon code, so we may earn a commission if you buy through them — at no extra cost to you. We're telling you that up front, because radical transparency about our commercial ties beats pretending we have none.

② We only list vendors that clear this bar:

Highest-quality research-use-only (RUO) material
100% US-manufactured
Heavy third-party lab testing with published Certificates of Analysis (COAs)
