Compare the same form, size, and package
Use the full listing to distinguish a vial, capsule bottle, spray bottle, or raw powder before comparing totals.

Start with the product form
PeptideSpend keeps each product form separate. A shared peptide name does not make a vial and a capsule bottle the same listing. Use the form choices in the catalog to find the items you mean to compare.
Our bottle illustrations identify catalog forms. They are PeptideSpend artwork, not photographs of a vendor's packaging or evidence of what a vendor ships.
Keep the full size label
Compare the stated amount and the package description together. A 10mg listing and a 30mg listing are different sizes. For a blend, keep each component amount rather than treating the combined figure as the same product.
For capsules and sprays, check whether the vendor describes the amount for the whole package or for part of it. If the listing does not make that clear, ask the vendor before treating two packages as comparable.
Distinguish one item from a promotion
Read the item price alongside the number of items in the offer. A buy-one-get-one promotion may add an item without changing the price of the first one. A quantity discount can require several of the same listing.
Check the vendor's eligibility rules, package count, and code terms. PeptideSpend shows the promotion separately rather than treating an extra item as a lower listed size.
Request product-specific documents
A catalog comparison cannot supply storage, handling, or preparation instructions. Request the current product documentation from the vendor and use your laboratory's procedures.
PeptideSpend provides research-use price comparisons. We do not assess a product's suitability for an experiment or provide instructions for human or animal consumption.
