GLP-1, GLP-2 and GLP-3 Research Peptides in the USA

This is a buying guide for US laboratories sourcing our GLP-1, GLP-2 and GLP-3 research peptides; it is not a product listing. It explains what the three names mean on our site, what a certificate for a peptide of this length ought to report, the USD cost per milligram of every size and both 10-packs, and how a FedEx parcel from Utah differs from an import.

What the three names mean on exolabz.co

Each listing is named for the receptors it targets, nothing more. GLP-1 targets the GLP-1 receptor and no other. GLP-2 (GLP-1/GIP) is a dual incretin-receptor agonist: it targets the GLP-1 receptor and the GIP receptor. GLP-3 (GLP-1/GIP/Glucagon) adds the glucagon receptor to those two targets.

All twelve listings are in stock as this is written and are supplied as lyophilized research material. Incretin receptor pharmacology: GLP-1, GIP and glucagon receptors sets out how single, dual and triple targeting differ; the catalog shows the three families together.

The certificate a long peptide needs

• Identity by mass spectrometry against the complete molecule. If the sequence carries a side chain or linker, a calculated mass for the bare amino-acid chain is a check against the wrong molecule.
• Purity by HPLC with the method printed. An area percentage means nothing without the column, gradient and detection wavelength.
• Net peptide content as a separate figure. Label milligrams are gross; after counter-ion (usually TFA) and residual water, net content is typically 70–90% of label (see net peptide content explained).
• Aggregation state. Size-exclusion chromatography or dynamic light scattering shows whether a long chain is present as single molecules.
• A named laboratory, a method section and batch photographs. No printed lot number appears on our vials; a report is matched to a vial by cap color and crimp color against the published photographs.

There is no published third-party report for any GLP-1, GLP-2 or GLP-3 listing to cite here. Reports for tested lots of other products are on the certificates page, new ones are added as testing returns, and how to read a peptide certificate of analysis covers each item above.

Cost per milligram in USD for every size

exolabz.co list prices on 28 October 2026; the 10+ columns apply the cart’s 25% tier. The two 10-packs carry a fixed price, so their 10+ columns stay empty.

The 10 mg and 30 mg vials of GLP-3 are $187.00 apart on the sticker, and that gap says nothing about which milligram is cheaper; the per-milligram column does, and it is the only column that can be set against another vendor’s sizes. Our US price list ranks the catalog by it, and comparing research peptide prices per milligram adds the net-content caveat.

Three ways to buy ten vials of GLP-3

The list-price row is for reference only; ten vials in the cart always trigger the 25% tier. Past ten vials, pricing is quoted through the bulk orders page.

A US vendor or an import

Orders leave our facility in Utah as tracked FedEx Express domestic parcels in plain-label packaging, to US addresses only: all fifty states, Alaska and Hawaii among them, and Puerto Rico. Nothing crosses a border, so no customs declaration, duty or brokerage applies. Dispatch is usually within one business day of confirmation; orders after the day’s cut-off go with the next run, and late Friday orders wait until Monday. From dispatch, typical transit is 1–2 business days in the Mountain and Pacific states, 2–3 in the Midwest, Texas and the South, 3–4 in the Northeast and New England, and longer in Alaska and Hawaii; typical ranges, not guarantees. Shipping is free over $200 USD: the GLP-1 15 mg vial, every 20 mg vial and the 30 mg vial each clear that alone, while a 10 mg vial or a GLP-2 or GLP-3 15 mg vial pays the rate calculated at checkout. See where we ship and the shipping policy.

An import adds an exchange-rate conversion on a foreign-currency price, international shipping, and a parcel that can be held for inspection on entry. Importing research chemicals into the US vs ordering domestically compares the two routes.

Payment

Credit card and cryptocurrency are the two methods on exolabz.co, priced identically, with no discount or surcharge on either. The payment methods page describes each.

Quantity tiers on the single vials

The cart applies the tiers automatically, without a code, counting every vial it holds across all listings. The 15 mg sizes are worked below.

A first-order or win-back code sent by email is applied on top of the tier. A holiday code at 30% off list replaces quantity pricing while applied rather than adding to it.

On arrival

These vials ship as lyophilized powder, stable over a normal domestic transit, so there is no cold-chain. Once the parcel is in, the sealed vials go to 2–8 °C, protected from light and moisture, and each should come to room temperature ahead of its first opening so condensation stays off the powder. Within 7 calendar days, check the vial count against the packing slip, set cap and crimp colors against the batch photographs on the report you mean to cite, and look over the glass and crimps. Damaged or incorrect items reported with photographs inside that window are replaced or refunded under the refund and returns policy; receiving a research peptide shipment has the full checklist.

Five checks for any vendor in this class

1. Is the certificate from a named third-party laboratory, or an in-house printout?
2. Is the calculated mass for the complete molecule, side chain included where there is one?
3. Are column, gradient and wavelength printed beside the purity figure, and is net content reported on its own?
4. Can the vial be connected to the certificate, by lot number or by batch photographs?
5. What is the vendor’s answer when an independent test fails the specification? Under our purity guarantee the product and the testing fee are refunded once the unused material is returned together with the lab report.

Choosing a research peptide supplier in the USA takes each check further, and how to read a peptide certificate of analysis locates the mass, method and net-content lines on a report.

Product pages

Every size is linked from the price table; the entry points are GLP-1 10 mg, GLP-2 (GLP-1/GIP) 10 mg and GLP-3 (GLP-1/GIP/Glucagon) 10 mg, with the 10 mg 10-pack and 15 mg 10-pack for ten at once. The FAQ covers ordering, and the contact page takes anything else.
