Questions we actually get

Anyone 21 or older who confirms at checkout that the materials are for laboratory research only, will not be used in humans or animals, and will not be used in food, cosmetics or supplements. Some items are not offered to certain destinations.

The materials are sold as laboratory reagents and nothing else. They are not drugs, supplements, cosmetics or foods, they have not been evaluated for safety in people, and we do not offer or support their use in humans or animals. Ordering requires you to attest to this.

From a single manufacturer. Every order ships directly from that manufacturer's facility, and the customs paperwork describes the goods as research reagents.

Purity (HPLC) and identity (mass spectrometry) are tested for each batch. Where an independent laboratory report is available it is published with the laboratory's verification key so you can confirm it on the laboratory's own website; otherwise the manufacturer's QC certificate is published and labelled as such.

In cryptocurrency, through the payment page after checkout. The invoice shows the exact amount and address; the order is confirmed once the payment is confirmed on the network.

A flat rate per order under the free‑shipping threshold shown at checkout, free at or above it. Delivery is by tracked international post from the manufacturer; transit is typically measured in weeks and depends on your country's customs.

Not once it has shipped, because the reagents must stay sealed and correctly stored. If an item is damaged, missing, or does not match its test report, contact us within 14 days of delivery for a replacement or refund.

No. We supply reagents and their specifications only.

Peptides are chains of amino acids joined by amide bonds; anything up to roughly fifty residues is conventionally called a peptide rather than a protein. "Research" describes how they are supplied — as laboratory reagents with a specification, a batch number and a test report, with no approval for use in humans or animals. A few catalog items are not peptides at all: NAD+ is a coenzyme, AICAR a nucleoside analogue and MK-677 a small molecule.

It is an area percentage from a reversed-phase HPLC chromatogram: the peak belonging to the named peptide divided by the total area of every peak the UV detector recorded. It is relative to what absorbs UV, so water, counter-ions and residual salts do not appear in it, and it says nothing about identity — that is a separate test by mass spectrometry.

By mass spectrometry. The observed mass is compared with the mass calculated from the sequence, and for a peptide of a few thousand Daltons an agreement to one decimal place is a strong result. A mass match confirms composition rather than the order of residues.

Lyophilisation freezes the solution and removes water by sublimation under vacuum, leaving a dry cake. Peptide bonds hydrolyse in water, so removing it is what makes the material stable enough to ship and store. Each product page states the storage conditions its purity specification was written against.

Each specification table gives the storage line for that item: lyophilised peptides are specified at −20 °C, desiccated and protected from light; sterile solutions at 2–8 °C, protected from light. Those conditions describe how the material was qualified. Keep the batch report with the vials it describes.

Because the dry state is what confers stability. Lyophilised peptides tolerate transit at room temperature; the storage specification applies from the point the kit arrives. Kits travel by tracked international post from the manufacturer.

That depends on the material and the country, and it is the purchaser's responsibility to check. Some items are prescription biologics in most markets, some are prohibited by name in particular countries, and destinations under comprehensive sanctions are not served at all. Restricted items are marked, and the ship-to country is checked again at checkout.

Independent laboratory reports carry a verification key or report identifier that can be checked on the laboratory's own website; where a report on this site has one, it is shown next to the report. A file on its own proves nothing. Where only a manufacturer certificate exists for a batch, it is published and labelled as a manufacturer certificate.

GLOW is one vial containing BPC‑157 10 mg, GHK‑Cu 50 mg and TB‑500 10 mg. KLOW is the same three plus KPV 10 mg. The blue colour of the cake comes from the copper(II) ion in GHK‑Cu. Each component has its own product page with sequence, CAS number and molecular weight.

Sterile water containing 0.9% benzyl alcohol as a preservative, which inhibits the growth of organisms that enter the vial rather than sterilising the contents. It is supplied in 3 ml, 7 ml and 10 ml vials as a consumable, on the same research-use terms as everything else in the catalog.

Several are deliberately excluded. Semaglutide, tirzepatide, retatrutide and mazdutide are patented drug substances whose holders have taken action against research-use sellers; somatropin is excluded because distributing it outside approved use is a federal offence in the United States. The catalog is limited to items whose supply and testing we can stand behind.

Yes, by tracked international post from the manufacturer. Destinations under comprehensive sanctions are refused, some are flagged for review before dispatch, and individual items such as Melanotan I and II are not offered to countries that prohibit them. Selecting a ship-to country in the banner shows what is available for that destination.

The free peptide, unless the entry states otherwise. Synthetic peptides with basic residues are usually isolated as acetate or trifluoroacetate salts, so the mass in a vial includes counter-ions and residual water that the stated molecular weight does not account for.
