Sourcing KLOW Blend in Bulk: A Wholesale & White-Label Guide for EU Resellers

*For research-supply businesses only. KLOW Blend is a Research Use Only (RUO) laboratory reagent — not a medicine, supplement, cosmetic or medical device, and not for human or animal consumption. This article is about sourcing and logistics, not usage guidance.*

KLOW Blend combines four peptides — BPC-157, TB-500, GHK-Cu and KPV — in a single 80 mg lyophilised vial. Because these four are so often studied together in tissue-repair and extracellular-matrix research, a pre-combined reference vial is an efficient catalogue line for distributors and white-label brands. If you are a reseller planning to add it to your range, here is how bulk sourcing works at Peptworks and what to check before you commit.

Buy from EU stock, not from customs limbo

The single biggest variable in peptide wholesale is fulfilment. Peptworks holds KLOW Blend in stock already inside the EU, so orders move as intra-community shipments and clear in 3-5 business days with no customs. For a reseller, that means predictable lead times you can quote to your own customers, instead of open-ended import delays.

Two formats: bulk or white-label

You can buy KLOW Blend two ways:

• Bulk unbranded vials — plain stock you distribute under your own arrangements.
• White-label — vials labelled with your own brand and boxed, ready to sell.

White-label carries a one-time label setup fee of EUR 180 for orders under 100 units, and that fee is waived from 100 units. If you are launching a brand line, hitting the 100-unit threshold removes the setup cost entirely.

How the pricing actually works

Pricing is public and quoted per vial, with a single volume discount applied to the whole order based on your combined total units — not stacked per reference:

| Combined units | Price / vial | Discount |

|---|---|---|

| 100 | EUR 59.00 | base |

| 300 | EUR 48.38 | -18% |

| 500 | EUR 44.25 | -25% |

| 1000 | EUR 40.12 | -32% |

The minimum order is 10 units (one box of 10) per reference, and vials always ship in boxes of 10. Because the discount tier is set by your combined total, you can mix KLOW Blend with other Peptworks references and still climb the volume ladder on the whole basket.

Quality and batch traceability your customers can verify

Every batch is made to >=98% HPLC purity and ships with an independent per-batch Certificate of Analysis covering HPLC and heavy metals. Each box carries the Peptworks label with a unique QR code that links straight to that batch's CoA, authenticated through Peptworks. For a white-label reseller, this is a selling point you can pass directly to research customers: traceable, per-batch documentation rather than an unverifiable claim.

Payment and paperwork

Orders are settled by USDC bank transfer / invoice — there is no card checkout on site, which suits B2B accounting workflows. The full Peptworks site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL), so multi-market resellers can operate in their buyers' language.

A practical first order

A common starting point is a 100-unit order: it hits the base per-vial tier, and — crucially for white-label — it waives the EUR 180 label setup fee. From there, 300, 500 and 1000-unit tiers unlock progressively better per-vial economics as your own demand grows.

The bottom line

For an EU research-supply business, KLOW Blend is a clean bulk or white-label line: EU stock with fast intra-community shipping, transparent per-vial volume pricing, a low 10-unit minimum, and verifiable per-batch CoAs. Keep every listing framed as Research Use Only — no human or animal claims — and the compliance story stays as tidy as the logistics.
