How it works

Peptide Price Checker

Search for any compound below to see its per-milligram pricing across every tracked supplier. Use the sort and filter controls to narrow results by form, stock status, or price range. Every price links to the supplier’s own product page where you can verify availability and purchase directly. PepLookup never handles the order.

Step by step

How to Use the Peptide Price Checker

  1. Search a compound. Type a name such as BPC-157, TB-500 or tirzepatide, or tap a popular shortcut.

  2. Filter the list. Narrow by category, supplier, dose, stock status or price range.

  3. Compare cost per mg. Each supplier's listing is converted to price per mg so different vial sizes line up. Click through to the supplier's own site to see the current price.

Method

How Price per mg Is Calculated

We divide each listed price by the total milligrams in the product. A 10 mg vial listed at $50 is $5.00 per mg. Where a sitewide coupon applies, we show the original price struck through and the price after the discount. The code must be entered at the supplier’s checkout.

Price per mg compares the amount of compound you get for your money. It does not compare purity, testing or quality, so read the supplier’s COA before you decide. Prices change as supplier catalogs change, and each listing shows when its price was last observed.

Price factors

Why Peptide Prices Differ Between Suppliers

The same compound can vary widely in price per mg. Common reasons include vial size (larger vials are often cheaper per mg), whether the supplier publishes a COA, shipping cost, stock status and active coupon codes. A low price per mg is a starting point, not a verdict. Compare shipping and the supplier’s published lab reports as well.

Questions

Frequently asked questions.

How is the price checker different from the supplier directory?
The supplier directory shows each supplier's full profile, including shipping terms, payment methods, review ratings and coupon codes. The price checker focuses on per-compound pricing: it groups every listing for a single compound across all tracked suppliers so you can compare cost per milligram in one view.
How often are prices updated?
Every listing carries the time its price was last observed. Prices are refreshed as supplier catalogues change, and the timestamp is the honest limit of what we can promise: the figure was correct when we recorded it, not necessarily at the moment you read it. Confirm the current price on the supplier's own page before ordering.
What does the strikethrough price mean?
A strikethrough price is the supplier's original list price before a sitewide coupon code is applied. The lower figure next to it is the price after the discount. Both are shown so you can see exactly how much the code saves. You still need to enter the code at the supplier's checkout for the discount to take effect.
What is a peptide price checker?
A peptide price checker compares the listed price of the same research compound across multiple suppliers. PepLookup normalizes each listing to cost per mg, so different vial sizes can be compared like for like.
How is peptide price per mg calculated?
We divide the listed price by the total milligrams in the product. A 10 mg vial at $50 is $5.00 per mg. Prices shown are what suppliers list, so check the supplier's site for the current price before ordering.
