Every batch tested before it’s listed

Every vial label carries a lot code. The QR code on the label, where present, opens the lab's own report for that lot; the certificate library here lists the same lot by its code. To check a vial, compare the lot code on the label with the lot code on the certificate; they should be identical. Our certificates are issued by Janoshik Analytical, an independent testing laboratory, not written by us. Each report carries the lab's task number and verification key, so you can confirm on Janoshik's own site that the report is genuine and unaltered. The certificate states the measured HPLC purity and, where the batch was tested for them, identity, net content and endotoxin. If the lot code on a vial you received does not match any published certificate, message us on WhatsApp with your order number and a clear photo of the label.

HPLC (high-performance liquid chromatography) is the analytical method used to measure how much of a vial's contents is the target peptide versus impurities. When JP Peptides lists a compound at 99%+ purity, that figure comes from an HPLC assay performed on that batch, not a manufacturer estimate. Each result is recorded on a Certificate of Analysis tied to the batch code printed on your vial. HPLC separates the sample into its components and quantifies each one, so a 99.2% reading means 99.2% of the material is the named peptide. This matters for research because impurities introduce variables that compromise reproducibility. Every listed batch is lyophilised under nitrogen and its full COA is viewable online, so the purity figure is independently verifiable rather than taken on trust.

A Certificate of Analysis is a lab document that reports the measured identity and purity of a specific production batch. For research peptides it typically states the compound name, batch number, HPLC purity percentage, and the testing date. JP Peptides publishes a COA for every verified batch and ties it to the batch code on the vial, so the document corresponds to the exact material in hand — not a generic sample. A COA matters because peptide quality varies between suppliers and batches; without one, purity is an unverifiable claim. Reviewing the COA lets a researcher confirm the compound is what the label says before using it, which is the baseline for reproducible work. COAs for current verified batches are also viewable on each product page.

A certificate reports only the tests Janoshik Analytical ran on that lot, and nothing more. Every published lot is tested for purity by HPLC; depending on the compound and the lot, the report may also include identity by mass spectrometry, the measured net content of the vial and an endotoxin result. The assays listed on the report are the ones that were done. If a test does not appear, it was not performed on that lot, and we do not claim a result for it. A certificate also says nothing about how a compound behaves in a biological system: it is an analytical record of the material in the vial. We publish each certificate only against the lot it was issued for; a report from one lot is never reused for another.

Add the compounds you need to the cart from the catalogue, then go to checkout. No account is needed: checkout asks for your name, phone number and delivery address, with email optional. Before the order goes through you tick three confirmations: that the material is for laboratory research only, that you are 18 or older and accept our terms and refund policy, and that you understand we give no dosing or usage guidance. Place the order as cash on delivery. The confirmation screen then shows your order number in the format JP-YYMMDD followed by a sequence number. Keep it: it is your reference for payment, tracking and support. We confirm every order with you on WhatsApp before it is packed.

Yes, as long as it has not been dispatched. Message us on WhatsApp with your order number and tell us what you need: a different compound or quantity, a corrected address or phone number, or a full cancellation. Orders confirmed before 2 PM IST on a working day usually leave the same day, so the sooner you write, the more likely the change goes through. If you cancel before dispatch, the cash-on-delivery order is simply not sent and there is nothing to pay. Once the parcel is with the courier the order can no longer be changed or cancelled; from then on the refund policy's 48-hour window for damaged or incorrect parcels applies, and a change of mind is not covered. Replies come within the hour between 9 AM and 6 PM IST, Monday to Saturday.

Volume pricing lowers the price per vial when you order more than one vial of the same compound. Where a compound has volume tiers, its product page lists them with the percentage off and the per-vial price for each step. The tier is applied automatically in the cart as soon as the quantity of that compound reaches it, so there is no code to enter and nothing to claim afterwards. Tiers count vials of one compound only: two different compounds at one vial each both stay at the single-vial price. The discount comes off before the free-shipping check, so a volume order often crosses the ₹5,000 free-shipping line on its own. Every vial in a larger order comes from a tested batch with its certificate published online, exactly as a single vial does.

JP Peptides takes cash on delivery (COD). You place the order, we confirm it with you on WhatsApp and dispatch it, and you pay the courier in cash when the parcel reaches you, so nothing is paid upfront. The amount is the order total shown at checkout and on the confirmation screen. Prices are listed and charged in Indian rupees, with no currency conversion. Shipping is free once the order total after discounts reaches ₹5,000; below that a flat ₹149 applies. No account is needed at checkout: your order number is the only reference you need for tracking and support.

Cash on delivery lets you order without paying anything upfront. Choose it at checkout and place the order; we confirm it with you on WhatsApp, then pack it and hand it to the courier. When the parcel reaches you, you pay the courier the order total in cash, which includes the flat ₹149 shipping charge on orders below ₹5,000. Keeping the exact amount ready helps, as couriers do not always carry change. Nothing is paid or entered online. The tracking number is shared with you on WhatsApp once the courier collects the parcel, so you can see roughly when to expect it. If your plans change before dispatch, message us with your order number and we can change the order or cancel it.

JP Peptides ships within India only. Orders placed before 2 PM IST, Monday to Saturday, are dispatched the same day; orders placed later leave on the next dispatch day. Every vial travels lyophilised with a cold pack inside insulated packaging, because temperature control matters for compound stability in transit. Each parcel is tracked, and the tracking number is shared with you on WhatsApp once the courier collects it. Couriers usually deliver within 3–7 business days of dispatch across India, depending on the destination pin code. Shipping is free once the order total reaches ₹5,000; below that a flat ₹149 applies. You pay the courier in cash on delivery. Every batch’s certificate of analysis is viewable online, so the documentation is available before the parcel arrives.
