How to buy research peptides wholesale

Buying research peptides wholesale means ordering by the kit, working through an order sheet, a PO and a pro-forma invoice, and paying by wire or crypto. Here is the process end to end.

Research peptides wholesale: the basics

On B2B Kits, the unit of sale is the kit: a sealed carton of 10 vials, one compound, one size, one lot. A single kit never mixes compounds or sizes, and we do not split kits or sell single vials. The catalog covers four groups — Peptides, Blends, Spray format research solutions, and Lab supplies such as bacteriostatic water — across 64 products and 118 kit SKUs.

Every order has a 50-kit minimum. Those 50 kits can be one compound and one size, or a spread across the whole catalog — the minimum is counted across the order, not per SKU. Start building an order at the catalog, where each product page shows the kit sizes on offer.

Buyers here are laboratories, research-supply distributors, online resellers and institutions buying for research purposes. There is no retail storefront and no single-vial checkout; everything is priced and sold by the kit, for buyers who already know they are placing a wholesale order.

Pricing tiers and volume quotes

Price is set by the total number of kits on one order, and the tier applies to every kit on that order. Standard pricing covers 50–99 kits. Volume pricing — the lowest listed price per kit — applies at 100 kits and up. Both tiers are published; nothing above Volume is published.

Orders of 500 kits or more move to a custom quote, with the per-kit price negotiated directly. Orders of 1,000 kits or more can run on a contract, priced on a monthly or quarterly schedule. If you already hold a lower written or published US wholesale quote for the same compound, size and form, in stock, with a third-party COA for the lot, ask for a price match. See tiers, margins and the order math for a full walk-through of how the tiers affect your per-kit cost.

Both tiers are visible on every kit's catalog page, so you can see the per-kit price change as the kit count rises, before you ever submit a PO. That lets you model an order's cost from the catalog alone, right up to the point where volume moves into custom-quote territory.

Mixing SKUs to reach your minimum

Kits of different compounds and different sizes combine freely on a single order and a single pro-forma invoice. A lab ordering for several projects, or a reseller stocking a catalog, can reach 50 kits — or cross into Volume pricing at 100 — by combining a GLP-series research peptide, a copper-peptide blend, and bacteriostatic water, rather than committing to one SKU at high volume.

This also makes it practical to add a small kit count of a new compound while your core volume sits in SKUs you already move. The tier is set by the order total, so a few kits of something new does not cost you the Volume price on everything else.

The same logic applies across every category. A buyer stocking the Spray format line, the Blends line, and Lab supplies like bacteriostatic water can treat all of it as one order rather than three separate minimums. Four categories, 64 products and 118 kit SKUs give a lot of room to build an order that matches actual demand rather than rounding up to hit a minimum on a single SKU.

From order sheet to pro-forma invoice

There is no account to create and no approval step. Build an order sheet at /catalog, listing the compounds, sizes and kit counts you want, then submit it as a PO at /order. A pro-forma invoice comes back by email with the freight charge and payment instructions for that order.

Payment is by wire transfer or cryptocurrency; see payment terms. The order releases to the warehouse once funds clear, then ships by FedEx from a US warehouse — the same business day when released by noon Central, otherwise the next business day.

The pro-forma invoice itemizes the kits on your order at the tier price, states the freight charge, and lists the wire or crypto details for that specific order — it is built from the order sheet you submitted, not a generic template. Review it against your PO before sending payment; a message to [email protected] before you send funds is faster to resolve than one after.

What to have ready before you submit a PO

Have the compound, size and kit count for each line settled before you fill out the order sheet — this is what sets your tier and your freight weight. Have a shipping address and a contact for the pro-forma invoice. Have your remittance method decided, since the invoice only carries wire and crypto instructions.

Every kit ships with the lot certificate of analysis for what is inside it — see how every lot is tested and how to read a peptide COA before you order, so you know what the paperwork should show when the kits arrive. Questions on a PO, a quote or a pending order go to [email protected].

If you are new to this catalog, decide ahead of time which sizes you actually need per compound — sizes vary by product, and the size you choose is part of what the kit locks in at one lot. Changing a size after the pro-forma is issued means a new order sheet, not an edit to the one in progress.

If something arrives short or damaged

Shortages and transit damage are handled the same way: photograph the carton and the contents within 48 hours of delivery and send the photos to [email protected] with your PO number. We file the carrier claim and replace confirmed damage or shortages.
