Index Peptides Review: Janoshik Lot Reports, Vial Lookup and 30-Day Returns

Index Peptides is a UK research peptide supplier operated by SORVA GROUP LTD, a company registered in England and Wales with its registered office in Poole, Dorset. It sells a compact catalog of about 29 listings to researchers and laboratories, with dispatch from the UK.

This review covers what the supplier publishes about testing, certificates, labeling and policies. Its documentation is built around the lot number printed on each vial, which links to a report from a named lab. The main gap is identity testing: purity and content are shown, but mass spec identity results are not.

Who Index Peptides is and what the catalog covers

The catalog listed 29 items when we looked. It includes single peptides in 5 mg to 40 mg vials, several multi-compound blends of up to 80 mg, NAD+ at 500 mg and 1,000 mg, glutathione at 1,500 mg, and 3 ml bacteriostatic water. Product pages describe the material as lyophilized powder in single vials.

Prices seen ranged from about £9.99 for a 5 mg BPC-157 vial to about £69.99 for a 1,000 mg NAD+ vial. Prices are in GBP, and a priced pro-forma invoice can be requested for institutional orders.

The supplier says no product is listed until its batch number, label, supplier documents, storage condition and limitation notes have been reviewed, and that it makes no purity or identity claim for a lot without a published report.

Testing and certificates: Janoshik reports matched to vial lots

Every batch record names Janoshik Analytical in the Czech Republic as the testing lab, with a lab report number and a test date. The certificate hub listed 36 lot records when we looked, each linking to a report image and a batch page. Single peptides show an RP-HPLC purity figure, mostly between about 98.7% and 99.9%. Blends and NAD+ show content results without a purity figure.

Each product page names the current lot, for example IP-BPC5-001 for the 5 mg BPC-157 vial, and shows its purity, measured content per vial (5.56 mg against a declared 5 mg in that case), lab and report date. A lookup page returns the same record when a buyer enters the lot number printed on the vial label. Older lots stay listed and are marked as superseded.

Identity is the gap. The FAQ says identity is typically confirmed by LC-MS, but product pages state that no LC-MS identity result is published, and the site itself notes that a purity result alone does not confirm identity or sterility. Some report numbers also appear on two different lots or products, such as one report shared by Melanotan-1 and Melanotan-2 lots, so buyers should open the report and check that it matches the lot they hold.

Labeling and purchase checks

Research-use-only and not-for-human-or-veterinary-use notices appear on the homepage, product pages, guides and support pages. Product pages also state that the material is not a drug, food or cosmetic. The guides we looked at discuss documentation and published laboratory work only, with no usage instructions or health claims, and support staff answer questions on specifications, documents and orders only.

There is no age gate on entry, but checkout asks buyers to confirm they are 18 or over and buying for research. The terms limit sales to qualified researchers and licensed laboratories, bar resale for human or veterinary use, and let the supplier cancel orders that do not appear to be for research.

Ordering, payment and shipping

Payment options shown include Pay by Bank through UK open banking, cryptocurrency, and international bank transfer on request. The terms say card payment may also appear at checkout.

Paid, in-stock orders placed before 4pm on business days usually ship the same day. UK and Northern Ireland orders go by DPD Next Day, free on product subtotals of £30 or more and £4.99 below that. Republic of Ireland orders use DPD or Royal Mail International Tracked, and other destinations are priced by country, with customs charges paid by the buyer.

An optional £6 shipping protection add-on covers parcels confirmed lost, delivered damaged or seized by customs, with a reship or full refund on request. The shipping page does not describe packaging or cold packs.

Refunds, reships and support

Unopened, unused items with seals and labels intact can be returned within 30 days of delivery for any reason, with the buyer paying return postage and no restocking fee. Damaged, faulty or incorrect items are replaced or refunded whether or not they were opened, and the supplier covers return postage in those cases. Buyers must email before sending anything back, and approved refunds are normally paid within 14 days.

Support runs by email, a contact form and a UK phone number, with WhatsApp for questions only, every day from 9am to 9pm UK time. The supplier states that it will never ask for payment over WhatsApp.

Verdict: strong lot traceability, identity data still needed

Index Peptides suits labs that want a named lab and a lot number they can check against a report before opening a vial. Its written terms and company details are complete and easy to find.

Before ordering, look up the lot on the product page, open the linked report and confirm it with Janoshik using the report number. If identity matters for the work, ask whether LC-MS data exists for that lot, and check that any shared report number covers the exact product being bought.
