Peptides in Amman: research supply, documentation and delivery

Compliance, classification and buyer responsibility

The classification is research reference material for in-vitro characterisation, and it does not change by destination. It is not a medicine, not for human or veterinary administration, and not sold for therapeutic, diagnostic or cosmetic use. Buyers in Jordan are responsible for confirming that their intended research use complies with local rules before ordering. We do not run discounts, so the figure you see is the figure you pay.

Import rules for research reference material in Jordan remain the buyer's responsibility to confirm before ordering. Batch numbers on the vial cap should match the certificate exactly — if they do not, stop and ask us before opening anything. Import rules for research reference material in Jordan 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.

Verification: HPLC, mass spec, batch records

Purity is measured by independent HPLC; identity is confirmed separately by mass spectrometry. There is no in-house testing theatre here: the report either supports release or it does not. Purity sits above 99% across the catalogue, and the chromatogram is part of the certificate rather than a claim printed next to it. Pricing is quoted in EUR, with shipping shown separately rather than folded into the unit price. Documents are sent on request ahead of payment so nothing is bought sight-unseen from Amman.

Pricing is quoted in EUR, with shipping shown separately rather than folded into the unit price. Copies are re-sent whenever a lab needs them for its records. We do not run discounts, so the figure you see is the figure you pay. Where work is split between Amman and another site, matched batches remove a common source of unexplained variance.

Getting an order to Amman

Packing happens within a working day or three of the order being confirmed. The practical difference between suppliers is rarely the vial; it is whether anyone can tell you what is inside it. The tracked leg to Amman then takes 5–18 business days from the moment tracking goes active. We do not quote a shorter window to close a sale. Material moves by a tracked delivery service; the route and carrier depend on the dispatch hub. Import rules for research reference material in Jordan remain the buyer's responsibility to confirm before ordering.

Outlying districts and industrial parks around Amman follow the same delivery leg. Collection points in Zarqa, Irbid and Aqaba are handled identically. Smaller towns around Irbid receive the same tracked service as the main city. For teams working across Zarqa, Irbid and Aqaba, keeping one shared log of batch numbers saves a lot of retrospective guesswork. You get a tracking reference at dispatch and a named contact who stays available while the parcel is moving.

Handling, storage and freeze-thaw

Transit is rarely where potency is lost. Local storage is. For teams working across Zarqa, Irbid and Aqaba, keeping one shared log of batch numbers saves a lot of retrospective guesswork. Keep it cold and dark: 2–8 °C for months, −20 °C for longer. Split into working aliquots before the first freeze — cycling a single vial repeatedly is what degrades it.

Seasonal heat around Amman is handled with cold packs rather than by hoping for a quick transit. Couriers serving Amman occasionally hold parcels for documentation, which is why the research-use declaration travels with every shipment. Our documentation is written for someone who will have to defend the sourcing decision later. Solvent and stability notes are published per compound rather than as one generic sheet. We do not publish dose tables or calculators of any kind.

Closing notes for Amman

Reference material only earns its price when the paperwork holds up. That is the standard we hold for Amman orders, and it is the one worth holding any supplier to.
