Your first order, and what to know before it.

What you are buying

Research peptides are supplied as lyophilized powder in a sealed vial. That is the product: a measured mass of dry material, not a solution and not a device. You add the solvent yourself when you are ready to use it.

The listed format is the mass in the vial, so 5 mg and 10 mg of the same compound are the same substance in different quantities. Price per milligram is the honest comparison, not price per vial.

Each compound sits somewhere different on the evidence scale. Some are approved medicines with large trial programmes; others have preclinical work only. Our product pages say which is which, including where the evidence is thin, because that is the part people find out too late.

Before you pay

Ask for the certificate of analysis for the batch you are being sent. Not for the compound in general, and not one with the batch number missing. This is the single check that separates suppliers, and it costs you one message.

Confirm the exact item, the format, the total in VND and the delivery window in writing. If the number changes later you have the earlier message.

Send a usable address. In Vietnam that means the building or hotel name, ward and district, alley number if there is one, floor or unit, whether reception takes parcels, and a phone number someone will answer. Couriers call rather than knock.

There is no checkout on this site by design. Nothing charges you before a person has confirmed the order.

What arrives

The vials, alcohol swabs and a mixing syringe, in protective packing inside a plain unbranded parcel. Bacteriostatic water is included when the order has two or more peptides.

The powder should be a compact cake or fine even layer at the bottom of the vial. Loose drifting dust or a cake stuck up the walls usually means heat or rough handling in transit, and it is much easier to raise at the door than an hour later.

Photograph anything that looks wrong before doing anything else. A photo taken on delivery settles almost every question.

Storage, in one paragraph

Sealed vials go in the fridge, on a shelf rather than the door, still in their box. They are stable at room temperature for the days a shipment takes, which is why they travel dry, but steady cold is better than a cupboard in Da Nang.

Once reconstituted, the solution stays refrigerated and never goes in the freezer. Bacteriostatic water is the usual solvent because the preservative in it is what allows a vial to be entered more than once. Sterile water and saline have no preservative.

The mistakes that cost money

Buying on headline price without checking the mass. A cheaper vial holding less material is not cheaper, and vial size is the easiest thing for a listing to change quietly.

Reconstituting with sterile water and then treating the vial as multi-entry. That is the most common handling error we hear described.

Ordering from overseas to save on the listing price and meeting customs. A held parcel means storage fees, broker fees and a warehouse with no temperature control. The overseas number is a price; a domestic one is a delivered cost.

Not asking for the certificate because it feels awkward. Suppliers who test expect the question. Suppliers who do not will offer you something else instead, and that answer is the information you wanted.

Where to go next

If you know the research area but not the compound, the catalog is grouped by area on the choose-by-area page. If you know the compound, its product page has the format, price, photos and evidence base.

If you want to work out concentrations before ordering, every compound has its own calculator with that compound's real vial sizes as presets.

If you are comparing us with another supplier, the supplier checklist is a nine-point comparison you can run on both of us equally.
