Match the product. Confirm the compound name, vial strength, product page, and stock record before comparing price.
Read the test scope. Identity, purity, measured content, endotoxin, sterility, residual solvents, and heavy metals are separate questions.
Match the lot. A public library is useful only when the delivered product and lot can be tied to a current report.
Check the final total. Package quantity, discount, payment fee, mandatory fee, and shipping can change the checkout cost.
Preserve unknowns. If origin, delivery time, return terms, or a test category is not documented, treat it as unknown rather than assuming the best or worst.
Buying from the United States
The current catalog identifies 21 listings with a shipping label that includes the United States. That is a dated comparison field, not legal advice or a delivery guarantee. A vendor may restrict particular states, addresses, products, or payment methods even when its general shipping record includes the US.
Use the shipping filter on the price homepage, then verify the destination on the exact vendor checkout. PeptidePrices does not infer eligibility from a company address, and it does not treat an unknown shipping field as evidence that a vendor will or will not ship.
International shipping and customs
4 listings currently carry an international or worldwide label. The label cannot answer country-specific import rules, customs delays, duties, seizure risk, or carrier limits. Those factors change by destination and are not represented as a simple catalog score.
Before relying on international availability, check whether the vendor names the destination, whether tracking is included, who bears customs responsibility, and what the refund policy says when a shipment is delayed or rejected.
Payment methods and checkout risk
Card checkout appears on 19 current listings, bank transfer on 5, and cryptocurrency on 3. The groups overlap. A vendor can offer more than one method, and the presence of a method does not increase the PeptidePrices quality rating.
Compare the ability to dispute a payment, mandatory processing fees, discount requirements, settlement timing, and the written refund policy. A low advertised price can become a different final total after fees and shipping.
Testing, COAs, and lot matching
21 current vendor records are associated with public COA access. 14 vendor COA programs are marked as checked by PeptidePrices. These are useful vendor-level evidence fields, but neither count proves that a ARA-290 listing or received vial is the sample on a report.
Read the full report. Confirm the named compound, product strength, lot number, laboratory, test date, and every test performed. Purity alone does not establish identity, measured fill, sterility, endotoxin, or stability.
Where current prices live
The homepage is the single owner of cheapest-price intent. It contains the sortable vendor table, shipping and payment filters, package prices, normalized 10mg costs, and the freshest catalog refresh. This page explains the decision process instead of duplicating that table.
