Putting your own label on wholesale peptides

Every reseller reaches the same fork within the first two or three orders. You have product landing, you have customers asking, and the vials in front of you are clear glass with nothing on them. What goes on the glass decides how the product is perceived and how much of your week goes on stickers.

There are three routes. They are not equally good, and the one most new brands start with is the one that costs the most in hours.

One: blank vials, label them yourself

The vials arrive with no printing. You buy a thermal transfer printer, a roll of polypropylene labels, and you spend an evening designing something in Canva. Startup cost is a couple of hundred dollars and you can change the design whenever you want.

It works, and for the first hundred vials it is the sensible answer. What it stops being is scalable. Applying a label straight onto a 2ml vial by hand is fiddly, and slightly crooked labels are the single most common tell that separates an amateur reseller from a brand. There is also the problem that domestic inkjet and thermal output smudges when it meets isopropyl alcohol, which is exactly what your customers will wipe the vial with.

Choose this if you are testing demand, if your volumes are under a box or two a month, or if you genuinely enjoy the control.

Two: factory printed, your artwork

You send artwork once. The manufacturer prints your labels and applies them before the vials go into trays, and what lands at your door is a finished, branded product. Nobody in the chain sees an unlabelled vial and neither do you.

The cost is lead time rather than money. Adding your artwork to a production run pushes dispatch out by a few days on the first order and usually by nothing at all on repeats, since the print file stays on file. Above a modest order size most suppliers absorb the print cost entirely, because a reseller with their own label printed at source is a reseller who reorders.

The catch is commitment. Once your artwork is at the factory, changing the design mid-run is not a five minute job. Get the label right before you send it, not after.

This is the route almost every established reseller ends up on, and most of them wasted six months on route one first.

Three: sell under the supplier's brand

You buy stock already labelled by the supplier and resell it as that brand. Zero setup, zero artwork, and the customer's loyalty attaches to the name on the vial rather than to you. Useful as a way to start selling this week. Bad as a business you intend to own.

What to put on the label

A vial label is small and there is a temptation to fill it. Resist that. What has to be there:

• Your brand name and mark
• The compound, written the way people search for it, not the systematic name
• Quantity in milligrams, and the word lyophilised if that is what it is
• A lot field
• Research use only, in words, not abbreviated

What does not belong on it: dosing, reconstitution volumes, storage instructions in small print, any claim about what the compound does. Those turn a research label into a drug label, which is a category you do not want your product to be in.

Getting the artwork right first time

The label area on a standard 2ml vial is around 30mm by 20mm. That is small. Set your type at a size that survives it, which in practice means a brand name at around 8pt and everything else at 5 to 6pt, and accept that only two lines of information will actually be readable at arm's length.

Supply a vector file, PDF or EPS or SVG, in CMYK, with fonts converted to outlines and a 1mm bleed. Print in one or two colours rather than a photographic gradient, because a small label printed on a curved surface flattens gradients into mud.

Ask for a print proof before the run. Any supplier who cannot show you one before printing a thousand labels with your name on them is not a supplier you want printing a thousand labels with your name on them.

Where Halden sits

We supply all three ways. Blank vials by default, at no cost and no added lead time. Your own artwork printed and applied at the factory, free above a modest order size, with a proof sent to you before anything runs. Or Halden labelled stock if you want to sell something this week while your own brand is being set up.

The labelling page has the artwork spec and the lead times. The catalogue prices everything by the box of ten.
