White label whey protein starts with an existing formula packed under your brand. Ask for the approved recipe code, what can change and the minimum order quantity (MOQ) for each flavor and pack size. Use the minimum-order example before committing to printed packaging.
Decide what will stay fixed
Ask for a formula or specification code on each sample. Agree which whey base, protein declaration, flavor and sweetener stay fixed when you apply your label. In a stock program you may have a choice of pack sizes or labels. A change to the protein target, sweetener or flavor system may move the order into a custom program. Put the agreed boundaries in the quote so the production team works to the same version that you tasted.
| Decision | Flavored stock whey | Unflavored stock whey |
|---|---|---|
| Recipe to request | Named flavor, sweetener system and ingredient list for that version | Ingredient list and any lecithin or other ingredient used to improve mixing |
| Sample to approve | Check sweetness, aftertaste and color at the labelled mixing ratio | Check the natural dairy taste, foam and performance in the intended recipe |
| Quote to compare | MOQ and price for each flavor and pack size | MOQ and price for the unflavored SKU in the same pack size |
| Reorder to agree | Keep the approved flavor code and define changes that require a new sample | Confirm the same ingredient specification and acceptable variation |
Unflavored describes the flavor treatment. If your brief also calls for no added sweeteners or a single-ingredient powder, check that separately against the ingredient list.
Calculate the first order by SKU
If the supplier sets a minimum for each flavor and pack size, add the minimums for every combination you plan to order. Confirm whether you can split a production run across pack sizes.
Suppose a quote has a minimum of 400 units per flavor and pack size. Chocolate and vanilla in one 1 kg format would require at least 800 units. Adding a second pack size for both flavors would take the example to 1,600 units if the same minimum applies. Ask whether the supplier can split production across pack sizes and whether printed pouches or labels have a separate minimum. These numbers illustrate quote math.
Compare the sellable order cost, including any one-time artwork or setup charges. A supplier with a lower per-unit price can still require more cash up front if the packaging minimum is higher or unused printed stock is charged separately.
Approve the sample and the repeat order together
Run the same mixing test for every sample. Use the same powder weight, liquid volume and temperature, and record clumps and taste immediately and after five minutes. Confirm in writing that the approved recipe, sample code and label version will be carried to the first order. Ask what happens if an ingredient changes before your next run.
Want to change the protein base or formula? Use the custom private label whey guide or the whey isolate sourcing guide. For finished Spartacus packs under the existing brand, read the wholesale whey protein distributor guide.
Ask which stock recipes can be quoted
Before printing origin claims on a white-label whey pack, review the distinction between UK supply and local Jordan packing in Spartacus’s manufacturer and packing explanation. Confirm the actual supply chain and permitted origin wording for your proposed formula, pack and destination.
When you order a stock whey formula alongside another product, keep the whey sample reference tied to its own label proof. The white label supplements guide explains how to check the separate blend, filling and printing minimums across a multi-product launch.
Send the destination, expected first order per flavor, pack size, labeling language and whether you need flavored or unflavored samples. Use Spartacus private label enquiries to confirm which recipes, formats and quantities are available for your project.
Documents behind a white-label whey quote
A stock whey formula should come with a named recipe version, ingredient list, protein declaration for the finished flavored or unflavored powder, sample approval and the destination-market label review. The Spartacus company certificates describe company-level trading and distribution scopes, not a laboratory test of a proposed white-label batch. The manufacturer disclosure describes the supply and Jordan packing of Spartacus-branded products; request a separate written description of who will manufacture and pack your own-label order. Send the exact formula, flavor, pack and market through the private-label enquiry page.
