How this research vendor comparison works
Compare available catalog entries across participating research vendors by listed strength, pack size and estimated cost per milligram. Where applicable, promotional pricing is calculated sequentially rather than by adding percentage discounts together. Saved catalog prices, stock information and promotional terms may differ from live checkout totals; entries with missing or older verification dates should be checked directly with the vendor before relying on a comparison.

Peptide Price Comparison Tool
Compare listed prices, coupon adjusted totals and true price per milligram. Pack pricing uses the total milligrams in every vial combined.
Saved prices and stock are estimates, not live checkout verification. Listings show their own source-check date; missing or invalid dates are marked Not verified, and source checks older than 7 days are marked stale. Listing checks are not checkout verification. Flawless, Glow, Iron Protocol and Glacier catalog prices and stock refreshed October 17, 2026. LabSourced uses 68 complete listings from the vendor catalogue PDF supplied October 17, 2026; five other advertised listings are not visible in that file. Glacier listings use stored catalog prices last reviewed October 17; any expired promotional prices must be reconfirmed before relying on rankings. PEPDEALS 10% is modeled once where eligible; 5- and 10-pack prices reflect the full pack. Coupon eligibility, bulk stacking, tax and shipping must be confirmed at checkout.
27 site vendors; 24 vendors in current USD calculator coverage. NextGenPeps and Vistara Labs are excluded from USD comparisons. Rankings use saved catalog prices, including listings marked stale or not verified; they are not verified live prices.

Pack price per mg calculator
Use this for any single vial, 5 pack or 10 pack. Enter the price for the entire pack, not the price of one vial.
How the math works: after code price = listed price × (1 − coupon percentage). Total mg = mg per vial × number of vials. Price per mg = after code price ÷ total effective mg. Active, calculable BOGO offers are reflected only on eligible SKUs. Shipping, tax, payment discounts, temporary promotions and product options selected after opening a vendor page can change the checkout total. Verify the current listing before ordering. Research use only.
