Contact and order support

Updated 2026-11-03 · PeptideTech editorial

PeptideTech is a comparison directory. It does not sell products, take payments or hold customer orders, so it cannot see, change or track an order.

Your supplier takes payment, fulfils your order, and handles delivery, returns and refunds under its own terms. Each vendor record links to the supplier’s official website, where its support contact and policies are published.

Where to get help

An order, a delivery or a refund

Contact the supplier you ordered from. Its vendor record links to its official website, where its support contact, shipping and refund terms are published.

A code or a price that looks wrong

Every offer shows when it was last checked. Prices and codes are re-checked automatically, partner stores update live, and a code is only deducted where a cart check recorded it.

Sell research compounds? List your store

Connect your WooCommerce store once: products are matched automatically, live prices and stock appear within minutes, and every lot certificate you publish is graded with the full breakdown. Self-serve, no listing fee; grades cannot be bought.

Check a price or listing

Open the offer’s original source and compare the exact product, size, form, currency and observation date. A changed checkout price can reflect a new source price, shipping, tax or coupon eligibility. Prices are re-checked automatically and partner stores update live; the verification policy explains how records and corrections are handled.

Historical PeptideTech records

The historical certificate archive preserves recovered documents from the former storefront. It does not authenticate current supplier stock or provide an order-support service for that storefront.
