ExoLabz supplies lyophilized research peptides to laboratories, universities and independent researchers across the United States, dispatched domestically from our US facility. Because stock sits inside the country, an order placed anywhere in the fifty states is a domestic parcel — no customs step, no duty, no brokerage fee and no open-ended clearance delay. The third-party reports we have obtained are published on our certificates of analysis page; not every compound in the catalog has one.

What we supply

Forty-four items across eight compound classes. Each is supplied as lyophilized powder in a sealed vial, for in vitro and analytical laboratory work only. The full catalog on one page is at the lab.

Several items are listed by receptor target — GLP-1, GLP-1/GIP, GLP-1/GIP/Glucagon — rather than by a familiar trade name. That is deliberate. A trade name belongs to an approved medicine with an approved indication, and applying it to a reference material implies an equivalence that does not exist. Naming by target describes what the molecule binds without borrowing a claim from a product we do not sell.

The same logic runs through the rest of the list. Where a compound has a widely used research designation it keeps it, because that designation is what appears in the literature and on the certificate: BPC-157, TB-500, SS-31, MOTS-C, GHK-Cu. Milligram figures in a product name refer to the mass of lyophilized peptide in the vial, not to a concentration, and blends state the combined mass across their constituents. If you are cross-referencing against a chemical database, search by name or sequence rather than by a record number — record identifiers are reassigned over time and a stale one resolves to the wrong entry.

Ten-packs are listed for the incretin blends, and pricing for larger or recurring laboratory orders is quoted on request. Purchase orders and institutional billing can be accommodated, and questions about lead times on a larger quantity are better sent before ordering than after, since availability is held against published stock.

Individual compounds

Shipping across the United States

Orders ship domestically to all fifty states, picked and dispatched from our US facility. Because stock sits inside the United States, a domestic order does not clear customs, and there is no import duty or carrier brokerage to account for. Transit is typically two to five business days depending on the service selected.

Several carrier options are presented at checkout with their own delivery estimates, so you can weigh cost against speed. Shipping is calculated at checkout and orders over $200 USD ship free anywhere in the United States. Transit bands for every state are tabulated on where we ship.

Orders placed before the daily cut-off on a business day are dispatched the same day; the rest leave the next business day. Every shipment is tracked and the number is emailed the moment the parcel leaves us. Details of accepted payment methods and what each order status means are on payment methods and how checkout works.

Receiving a shipment at a US address

Institutional addresses add a step that the carrier tracking does not show. A parcel marked delivered at a university or hospital has usually reached central receiving rather than the laboratory itself, and internal distribution can add anywhere from a few hours to a full working day. On a large campus that internal leg is worth planning for.

Lyophilized peptides are shipped as a dry powder and tolerate ambient transit, but a parcel that sits on an unattended loading dock is a different proposition from one signed for indoors. Timing a delivery to a staffed day is the single most useful thing a recipient can do.

Check the vial against the paperwork before anything goes into storage: cap and crimp color, the batch or lot marking, and the quantity against what was ordered. Vials do not carry a printed batch number, so the match is made against the documentation rather than the label. The full sequence is set out in what to check when a shipment arrives. Photograph anything that arrives damaged before opening the outer packaging, and contact us with the order number.

Storage once it arrives

Lyophilized material is stable enough to travel without a cold chain, but that tolerance is for transit rather than for storage. Once a vial is in the building it belongs in the conditions described in storage and stability of lyophilized research peptides, and leaving it on a bench at room temperature for a day is the most common avoidable handling error.

Reconstituted material follows different rules again — the relevant considerations are in choosing a reconstitution solvent and freeze-thaw cycles in peptide solutions. Auto-defrost freezers are the common failure point in a shared facility, because the cycling they rely on is exactly what the material should not see; that problem and the ways around it are covered in freezer storage and auto-defrost.

Who we supply

ExoLabz supplies laboratories, universities and institutional research programs across the United States.

Sale is restricted to research institutions, licensed researchers, universities and laboratory R&D purchasers. Resale, repackaging or supply for human or veterinary use is prohibited. Confirming that a given compound is lawful to receive and hold at your address is the purchaser’s obligation, not ours. Individual states maintain their own controlled substance schedules alongside the federal ones, and the method for checking both layers is set out in checking controlled substance status.

Certificates of analysis

The third-party reports we have obtained are published in full on our certificates of analysis page. Not every compound in the catalog has one, and a report covers the production lot it names rather than the product in general — a certificate is a batch record, not a standing claim about a supplier.

Purity is reported by RP-HPLC as area percentage, which describes the proportion of peptidic material that is the target sequence. It says nothing about sterility, endotoxin, residual solvents or net peptide content, all of which are separate tests. Where a test was not run, the certificate does not report it and neither do we. The figure that actually makes price comparisons meaningful is explained in net peptide content, and the terms of the purity commitment are set out on the purity guarantee page.

Regulatory position

Everything supplied here is for laboratory research use only. These compounds hold no FDA approval for human use, and they are not approved for human consumption or for clinical or veterinary application. They are not drugs, foods, cosmetics or medical devices, and they are not intended to diagnose, treat, cure, mitigate or prevent any disease.

We publish no dosing, administration or preparation guidance, and we do not provide it on request.

Common questions

How long does delivery within the USA take?

Typically two to five business days depending on the service selected at checkout. Several carrier options are presented with their own delivery estimates.

Is there a customs step?

No. Stock sits inside the United States, so a domestic order never crosses a border and no duty, brokerage or clearance applies at any point.

Who can order?

Research institutions, licensed researchers, universities and laboratory R&D purchasers. Resale, repackaging or supply for human or veterinary use is prohibited.

What does a certificate cover?

Identity and purity for the production lot it names. It does not establish sterility, endotoxin status, residual solvents or net peptide content, and not every compound in the catalog has a published report.

When does shipping become free?

Shipping is calculated at checkout, and orders over $200 USD ship free anywhere in the United States.
