BPC157 Stack is an independent review and comparison site for research peptide suppliers. We do not sell peptides directly. When you click a vendor link on this site and complete a purchase on that vendor's site, we may earn a commission at no extra cost to you. This is how we sustain the work of testing, ordering from, and writing about every vendor we review.
What is and isn't influenced by affiliate revenue
Not influenced: rankings, scoring across our five categories (purity & COA, price, shipping, service, selection), pros/cons lists, and cautionary notes. A vendor cannot pay to be ranked higher, included in our index, or have negative coverage removed.
Influenced by commercial reality: which vendors we have an affiliate relationship with. Some suppliers we review pay commission; others do not. We mark links as rel="nofollow sponsored" per FTC and search-engine guidelines. We do not hide or omit non-affiliate vendors from rankings.
Discount codes
When you use a discount code shown on this site, you save money and we receive attribution and (usually) a small commission. The codes shown are real and reduce your price; they are not rate-card-padded "fake discounts." If a code stops working, please email us so we can update it.
Research-use disclaimer
The compounds we review are research chemicals. They are not drugs, dietary supplements, food, or cosmetics. They are not for human or animal consumption, diagnosis, treatment, cure or prevention of any disease. Nothing on BPC157 Stack constitutes medical advice. Consult a qualified clinician for any health concern.
