About
An index built on a flat fee
Who we are
Peptide Compare is a trading name of ZESTEC Services Limited, a UK private limited company (company no. 16566434). Registered office: 20 Wenlock Road, London, England, N1 7GU. Company details are also on Companies House.
What we do
We collect prices from independent UK suppliers and normalise them to a price per milligram, so that different vial sizes can be compared on one scale. Each peptide has a short research profile summarising publicly available science.
What we don’t do
- We do not sell, stock, ship or supply any product.
- We do not process orders or payments for products.
- We do not give medical advice, dosing information or usage protocols.
- We do not endorse or guarantee any supplier.
How we are funded
Suppliers pay a flat subscription: £10 a month plus £1 for every product variant they list. We take no commission on any sale. Because the fee does not depend on sales or on position, price alone determines ranking. See the supplier pricing page and our disclosure.
