White label and private label: what the two words mean, and which one you need

Written 25 September 2026, last changed 16 October 2026 by the trade desk. About 8 minutes to read.

White label is a finished product sold to several resellers under their own names; private label is a run made to your order, under your presentation. One product behind many brands, against one run behind one brand, and choosing the wrong word costs a conversation with every supplier you approach.

The short answer

White label is an existing product, already made to somebody else's specification, sold to several resellers who each put their own name on it. Private label is a run made to your order, where the strength, the fill, the presentation and the label are yours, made to the line's own release specification.

One product behind many brands, against one run behind one brand. That is the whole distinction, and everything below follows from it.

White label: one product, many brands

The supplier has already decided what the product is. It is made, tested and held, and what is on offer is the right to sell it as yours. You choose which lines to carry and what to charge; you do not choose what goes in the vial, because that was settled before you arrived and it is the same for every other reseller carrying it.

What you are buying is speed. There is no run to commission and no minimum quantity beyond the ordinary one, and a line on the shelf leaves in 1 to 2 business days. What you give up is any claim to distinctiveness in the product itself: your competitor two websites away may be selling the same batch.

Private label: one brand, one run

Here the run is made because you ordered it. The compound, the strength, the fill, the presentation and the label are specified by you, and the quantity is whatever the run is for. Because nothing exists until it is commissioned, it is priced on a quote rather than taken off a list, and there is a lead time.

What is exclusive is the run, not the compound. No supplier can sell you exclusive rights to a sequence, and one who offers them is selling you something it cannot deliver. What a private-label run gives you is material at the strength and fill you chose, under your presentation, made to the line's release specification, against your order.

The two side by side

	White label	Private label
What exists when you ask	A finished product on a shelf	Nothing yet
Who sets the strength and fill	The supplier	You
Whose name the customer sees	Yours, on your shop and paperwork; the vial label is the line's own	Yours, on the label of the run
Release specification	The line's own	The line's own, as written on the quote
Who else can sell it	Any other reseller carrying the line	Nobody: the run is against your order
Minimum	The ordinary order minimum	Set by the run, and stated on the quote
Lead time	Shelf lines leave in 1 to 2 business days, made-to-order lines in about four weeks; special-order lines come on a 50-box minimum	On the quote; about four weeks is the general figure for anything the shelf cannot cover
How it is priced	Off the published price list	Quoted, not listed
Money committed before you sell anything	One order	A run

What neither of them changes

The release specification is the same under any label, and so is the certificate of analysis: for a peptide line, purity by RP-HPLC of not less than 98.0 percent, net content and identity by mass spectrometry, for the batch you receive. The unit of sale is the sealed box of ten vials either way, because a box is sealed at fill with its batch number on it and splitting one would break the link between the vials and the document that describes them.

To a US address, freight is included from $1,000 of goods on both routes, and the same minimum-order rules apply to the stock you buy.

The certificate does not carry your brand

This is the part most people selling under their own name get wrong, and it is worth being clear about before a customer asks you.

A certificate of analysis attests to a batch. It names the batch number, the compound and strength and the date of analysis, and, for a peptide line, reports three results, each with its method: purity by RP-HPLC, net content and identity by mass; protein, solution and ancillary lines report the results their own page lists. The limits are the specification on the compound page; the retest date is on the batch record. It is a laboratory record. Your brand is not a party to it and never appears on it, whichever route you took.

That is not a gap in what you are being sold. It is what makes the document worth anything: a release record that could be reissued with a different name at the top would prove nothing at all. What you hand your own customer is the batch number, and any batch number here can be looked up, for them as much as for you. A reseller who can produce that has something to say that most cannot. A supplier who offers to print your logo on a release document has told you what their documents are worth.

Which one you actually want

Most resellers who ask for private label want white label. They want their own brand in front of the customer, and they have assumed that means commissioning a run, because that is how the word is used in industries where the product is a formulation somebody blends for you. With single-compound research peptides the release specification is already fixed by what the compound is; there is no recipe to make yours. Branding the shop rather than the molecule gets you the same place for the price of an order rather than a run.

Private label earns its cost when you genuinely need something the list does not carry: a strength that is not stocked, a presentation that is not offered, or a quantity large enough that a dedicated run prices better than the list does.

How each one starts here

Both begin with a trade account. Who can open one and what is asked for is set out separately, and a first order can be small on purpose.

Selling stock lines under your own brand. Buy from the list and sell through your own channel, or ask the desk about running a storefront on your own domain on this catalogue and fulfilment, where you choose the lines and set the retail and carry no inventory.
A run made to your order. Raise it from your account under Quotes and RFQ with the compound, the quantity and the date you need it, and it comes back priced. Quantities beyond the price list and presentations not stocked go the same way.

If you are weighing suppliers for either route, what to check in a peptide supplier lists what to ask for before you commit, and price per milligram is how to compare two quotes that are not in the same units.

Questions about selling under your own brand

What is the difference between white label and private label?

White label is an existing product, already made to the supplier’s own specification, offered to several resellers who each sell it under their own name. Private label is a run made to your order: the strength, the fill, the presentation and the label are yours, the release specification is the line’s own, and the run belongs to your order rather than to a shared shelf. The short version is that white label is one product behind many brands, and private label is one run behind one brand.

What is a white-label company?

A supplier that makes or holds a finished product and lets other businesses sell it as their own. The reseller owns the brand, the customer relationship and the retail price; the supplier owns the specification, the stock and usually the testing. Nothing about the product itself changes as it passes from one to the other, which is the whole point: the reseller carries no manufacturing and often no inventory.

Can I put my own brand on peptides I buy wholesale?

On the vial, only through a private-label run, which is quoted and made to your order. On the shop, a storefront can run under your brand on your own domain on this catalogue, stock and fulfilment, with you choosing the lines and setting retail, while the vial label stays the line's own. Both start with a trade account, and which one suits you is mostly a question of how much you want to commit up front. Ask the desk before you commit to either.

Does the certificate of analysis carry my brand name?

No, and no supplier can make it. A certificate attests to a batch: it names the batch number, the compound and the date of analysis, and reports its results, each with its method (for a peptide line, purity by RP-HPLC, net content and identity by mass). It is a laboratory record, not a marketing document, and a brand name has no place in one. What you hand a customer under your own label is the batch number, which they can check against the register it was issued from the same way you can. A supplier who offers to put your logo on a release document is telling you something about the document.

Which route needs less money to start?

Selling stock lines under your own brand, because you are buying from a shelf that already exists. A first order can be as small as $100 of goods, one sealed box of ten per regular line, and no run has to be commissioned; the order minimum then steps up with the account. A run made to your order is quoted rather than listed, so the quantity and the lead time come back on the quote; the general figure for a regular line the shelf cannot cover is about four weeks.
