Compare price without losing the evidence
PeptidePrices separates package cost, normalized cost, vendor quality, and freshness so a cheap listing is never presented as proof of product quality.
Start with the checkout amount
Package price is the amount attached to the vendor's listed item. It is the clearest way to compare the immediate cash outlay, but it does not make different vial sizes equivalent.
Standardize eligible quantities
When package quantity is known, the index calculates a common reference amount. Listings with missing or ambiguous quantities stay out of that normalized ranking instead of receiving an invented value.
Check coverage and freshness
Vendor count shows how broad the comparison is. Listing-specific check dates show which prices and stock observations came from the latest successful scrape and which sources still carry an older receipt.
Open the vendor evidence
The cheapest row is only a price result. Vendor reviews separately evaluate public COAs, exact-domain customer reviews, business transparency, fulfillment terms, payment methods, and current reader offers.
Scheduled at 4:00 a.m. Eastern, dated by successful evidence
The automated price scraper runs every morning. The public “checked through” date advances from the newest successfully collected listing rather than from the schedule itself. If a vendor blocks the run, times out, or exposes no usable price, its previous receipt remains visible and the missing result stays unknown.
How do I compare peptide prices across vendors?
Choose a compound to compare standardized totals, package composition, stock, vendor evidence, and the date each listing was checked.
What does normalized peptide price mean?
A normalized price converts eligible vial listings to the same reference amount so differently sized packages can be compared. It is a pricing calculation, not a statement about purity, potency, or suitability.
Does the lowest listed price mean the vendor is recommended?
No. Price rank and vendor quality are separate. Review the vendor score, named-lab evidence, exact product and lot, shipping terms, payment methods, and listing check date before using a price comparison.
How current is the PeptidePrices price index?
The price scraper is scheduled to run every morning at 4:00 a.m. Eastern Time. The date shown here is not hard-coded: it comes from the newest successfully checked public listing, currently October 10, 2026. Each vendor row keeps its own check date because one failed or blocked source should not make older data look newly verified.
Why can two listings have different package and normalized price rankings?
Package price answers what the checkout item costs. Normalized price converts eligible listings to the same reference quantity, so a larger vial can cost more at checkout while costing less per standardized amount. PeptidePrices shows both because they answer different buying questions.
Are coupon discounts included in the displayed peptide price?
Verified percentage coupons are included in the displayed standardized total and shown with the original amount. Other promotions remain separate when their checkout effect cannot be calculated reliably.
What does in stock mean in the directory?
In stock means the latest successful vendor check exposed the listing as available. It is a dated storefront observation, not a guarantee that inventory will remain available after the check. Open the vendor page to confirm the current listing before relying on it.
Does PeptidePrices verify every COA shown by a vendor?
No. Vendor reviews distinguish public certificate access, named-lab documentation, lot linkage, test breadth, and independently verifiable reports. A vendor-level COA badge does not mean every product, strength, or lot has been tested to the same panel.
