White label and private label: what the two words mean, and which one you need
Written 25 September 2026 by the trade desk. About 5 minutes to read.
The two terms are used as if they were interchangeable, and they are not. They describe two different transactions, and choosing the wrong word costs you 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 specification and the presentation are yours.
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, no minimum quantity beyond the ordinary one, and no wait while something is made. 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. Nobody owns a peptide sequence, and a supplier who suggests otherwise is selling you something they cannot deliver. What a private-label run gives you is material made to your specification, under your presentation, 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 writes the specification | The supplier | You |
| 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 | Stock ships in 1 to 2 business days | On the quote; about two 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 standard is the same under any label: not less than 98.0 percent by RP-HPLC, with any single related substance not more than 1.0 percent, and a certificate of analysis for the batch in the box. 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.
Freight is included from $1,000 an order 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, the date of manufacture, the date of analysis, the retest date, and for every test the method, the limit and the result. 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 resolves against the testing laboratory's own record, 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 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 specification and the presentation are yours, 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?
Yes, by either route. 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; or a run can be quoted and made to your order. 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, the date of analysis, the method and limit for each test and the result. 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 laboratory record 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. The floor is $100 of goods on a first order and $300 after that, one sealed box of ten per line, and no run has to be commissioned. 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 anything the shelf cannot cover is about two weeks.
