The legal position, stated plainly
Everything in the catalogue is supplied as a research reference standard for in-vitro laboratory use. The practical difference between suppliers is rarely the vial; it is whether anyone can tell you what is inside it. Nothing here is a pharmaceutical, and nothing is supplied for use outside a laboratory setting. Local research-chemical rules vary; the buyer in India is responsible for checking them.
Nothing described here is a medicine, a treatment or a supplement — the material is in-vitro reference standard only. Import rules for research reference material in India remain the buyer's responsibility to confirm before ordering. If a shipment is inspected, the paperwork travelling with it describes exactly what the material is.
The chemistry, briefly
Peptides are short amino-acid chains. Everything that matters about one — identity, stability, behaviour in solution — follows from the exact sequence. A short message with your compound list is usually quicker than working through the catalogue alone from Kolkata. Synthesis leaves behind related impurities: truncated chains, deletion sequences, residual solvent. HPLC separates them out and quantifies what remains. Freeze-drying is what makes room-temperature transit survivable; it also means the vial needs correct reconstitution before use. Import rules for research reference material in India remain the buyer's responsibility to confirm before ordering.

Delivery window for Kolkata, explained honestly
Preparation takes one to three working days once the order is confirmed. After that the tracked leg into Kolkata runs 5–18 business days from the moment tracking goes active — worldwide, without exception and without a faster number quoted to win the order. Shipments travel via DHL Express International with tracked, insulated packaging. Import rules for research reference material in India remain the buyer's responsibility to confirm before ordering.
Repeat customers in Kolkata tend to settle on three or four compounds and stay with the same lots for consistency. Deliveries to the wider Kolkata area run on the same schedule as the core. Nearby Indore is covered on the same terms. Tracking goes live at dispatch. If a parcel stalls, we chase the courier rather than asking you to.
How purity is verified
Batches are released only after independent chromatographic purity testing and identity confirmation. Couriers serving Kolkata occasionally hold parcels for documentation, which is why the research-use declaration travels with every shipment. The result is published on the certificate as a chromatogram, not as a headline percentage with nothing behind it. Nothing on this page is a promise about outcomes; it describes handling, documentation and logistics for Kolkata, India. Ask for the batch number and certificate up front — that request is expected, not unusual.
Copies are re-sent whenever a lab needs them for its records. Pricing is quoted in EUR, with shipping shown separately rather than folded into the unit price. If a study spans locations, ask for batch matching at the quote stage rather than after dispatch.
Closing notes for Kolkata
If you take one thing from this page, make it the batch certificate. Everything else about sourcing peptides into Kolkata follows from being able to prove what is in the vial.
