Frequently asked questions
What is Peptide Compass?
Peptide Compass compares publicly documented vendor information. The provisional documentation score covers lab documentation, shop attributes and delivery information. Prices are compared separately by compound.
Are these real vendors?
Peptide Compass lists 24 real vendors with publicly documented facts as of Sep 15, 2026. Prices, batches and reviews will follow once collected.
What does the Ad label mean?
All shop links are labelled Ad. Peptidwerk is currently our affiliate partner. We may earn commission on a referred purchase. The label does not mean we have a partnership with every linked shop.
Are these substances approved for human use?
The research products compared here are not intended for human use. Research products and approved medicines must be considered separately. The status of the specific product matters.
