How to compare UK peptide prices

A step-by-step method for comparing UK research peptide prices on PeptidePrices: match the strength, work out the per-mg price, add delivery and a valid coupon, then check the matching COA.

Step 1: Find the compound in the price index

Open the UK price index and type the compound name into Search peptides. Each card shows the lowest listed in-stock price, the vendor listing it, how many vendors and offers we hold, and how many of those vendors have an exact issuer-verified COA.

The card price is a starting point, not a like-for-like answer: it can be a smaller vial than the one you want. Select Compare all vendors to open the full comparison for that compound.

Step 2: Choose one strength

On the compound page, use the Strength menu to show a single pack size, for example 5 mg or 10 mg. The menu only appears when vendors list more than one strength. A 5 mg vial and a 10 mg vial are different purchases, so compare within one strength first.

Check the package label under each price for the quantity and format. Vials, capsules, sprays and pens are different products. For blends, the total milligrams do not tell you the amount of each component; read the listing for the component amounts.

Step 3: Compare the per-mg price

Under each pack price the table shows the price per unit (for example per mg) and whether the item is in stock. In-stock offers are listed first, cheapest pack first. When you are deciding between strengths, the per-mg figure shows whether a larger vial is better value.

Each row also shows the date the price was checked. Prices can change after that date, so open View listing to confirm the current price on the vendor's site.

Step 4: Narrow by payment method if it matters

If you can only pay one way, use the Payment method menu. All payment methods shows every offer; choosing a method keeps only vendors whose recorded payment options include it. Use Clear filters to return to the full list.

Step 5: Work out the delivered total

Below the table, Recorded delivery terms lists each vendor's published delivery options, charges, any free-delivery threshold and the date we reviewed those terms. Where a vendor states that its threshold applies before discounts, we say so.

Then check the UK coupon codes page for a code's conditions and last verification date. Apply the code to the basket subtotal only if the order qualifies, then add delivery.

Worked example: a £60 basket with a 10% code becomes £54. If that vendor's free delivery starts at £60 after discounts, the £54 basket still pays delivery; if the threshold is measured before discounts, it may not. Compare the final checkout totals, not the list prices.

Step 6: Open the COA that matches the listing

Rows with a linked certificate have a button that opens the report from that vendor's archive. Rows without one say No exact COA linked. A linked report is matched to the vendor, compound and strength of that listing.

Read the report's compound, tested strength, lot, test date and laboratory. Purity and measured quantity answer different questions, so check both. The COA library separates reports confirmed with the issuing laboratory from files we have not been able to confirm.

Step 7: Check the vendor before ordering

The lowest price is only useful if the vendor's policies suit you. Select the vendor name in the table to read its UK review: rating, ordering and delivery policies, and laboratory coverage. Our methodology explains how ratings are scored.

Common questions

Why is the price on the index card different from the compound page?

The card shows the lowest in-stock price across all strengths. The compound page lets you choose one strength, which may have a higher lowest price.

Do the prices include delivery or coupons?

No. Listed prices are in pounds before any conditional coupon or delivery charge. Use the recorded delivery terms and the coupon page to work out the total.
