Custom peptide labels: what goes on, what never does.

What a peptide vial label should carry

A peptide vial label should carry seven things: the compound name, the amount per vial, the batch or lot number, a research use only statement, a storage instruction, the brand and a contact route. Anything beyond those seven needs a reason to be there, because every extra word on a small vial is a word that can be wrong.

• Compound name

  The compound's own name, spelled the standard way, for example GHK-Cu or BPC-157. For a blend, the blend name and, where it fits, its components.

• Amount per vial

  The amount of lyophilised powder in the vial, for example 10mg, matching the supplier's specification for that product exactly.

• Batch or lot number

  The supplier's batch number for that vial, printed exactly as the supplier issues it. More on why below.

• Research use only statement

  A plain line such as "For research use only. Not for human consumption." This is not decoration; it is the statement that describes what the product is.

• Storage instruction

  A short line such as "Store sealed vials frozen or refrigerated. Keep reconstituted vials refrigerated." consistent with what the supplier says for that product.

• Brand

  Your brand name or mark. On a small vial this usually goes at the top and is the largest text after the compound name.

• Contact route

  A website or a messaging handle where a question about the vial can be raised, so a batch query has somewhere to go.

Put the compound name and amount where they can be read without turning the vial. Batch number, storage and research use only lines can run smaller, but they still have to be legible to someone holding the vial in a fridge doorway.

What a peptide label must never carry

A peptide label must never carry dosing, health claims or the brand name of an approved medicine. Those three are where a label stops describing a product and starts making a claim the seller cannot support.

• No dosing or use instructions

  No amounts per draw, no frequencies, no schedules, no injection or administration directions. A label that tells someone how much to use has turned a research-use-only vial into something presented for human use.

• No health or outcome claims

  Nothing about weight, skin, recovery, sleep, energy or any other effect on a person. Not as a headline, not as a tagline and not as an icon that implies it.

• No pharmaceutical brand names

  Never the brand name of an approved medicine, and never "same as", "generic" or "alternative to" any branded product.

• No testing claims you cannot point to

  No purity percentages, no testing badges and no lab wording unless a published report for that exact batch covers it, scoped the way the report scopes it. Primara publishes lab reports per batch as they are issued, at /coa.

In the Philippines, health products are regulated by FDA Philippines under RA 9711, and labelling that presents an unregistered product as a medicine or makes therapeutic claims invites exactly the regulatory attention a small brand cannot afford. Research-use-only compounds are not approved for human use in the Philippines. Get your own legal advice on your labelling before you print a run, and read what peptide resellers should never say for the same rules applied to marketing.

Label materials for cold storage

Peptide vial labels need waterproof synthetic stock and a freezer-grade adhesive, because vials spend their life in a fridge or freezer and come out into Philippine humidity. A paper label with ordinary glue is fine on a dry shelf and fails within weeks in cold storage.

The failure is predictable. A cold vial taken out into a warm room collects condensation in seconds. Paper absorbs it, ink smears, and a standard adhesive that was applied at room temperature loosens at the edges. After a few cycles the label lifts, and a vial without a readable label is a vial nobody can identify.

• Stock

  A synthetic film such as polypropylene or polyester rather than paper. These do not absorb water and keep their shape in the cold.

• Adhesive

  An adhesive rated for freezer or cold-temperature use, ideally one that can be applied to a cool surface. Ask the label printer for the rated temperature range and check it covers your freezer.

• Print

  Thermal-transfer printing with a resin ribbon, or a print process the printer confirms is smudge resistant when wet. Ordinary inkjet on uncoated stock runs.

• Finish

  A matte finish if you or your buyers will write on the label; most gloss laminates do not take a pen.

Apply labels to clean, dry, room-temperature vials and give the adhesive time to set before the vials go into cold storage. Labelling a vial straight out of the freezer is the most common reason a good label still lifts.

Sizing labels for small vials

A label for a 2ml or 3ml vial has to fit the straight part of a very small glass body, which leaves far less room than most first designs assume. The usable area is the band between the vial's shoulder, where the glass narrows toward the cap, and the slight curve at its base.

Measure the vial you will actually receive rather than a drawing. Wrap a strip of paper around the vial, mark where it meets itself, and measure the straight height you can cover without reaching the shoulder or the base. Those two measurements are your maximum width and height.

Size the label slightly shorter than the full wrap so it leaves a narrow clear window. That window lets anyone see the powder or the liquid inside, check its colour and read the fill level without peeling anything. A label that wraps completely and overlaps itself also tends to lift at the overlap in the cold.

With that little space, hierarchy decides legibility. Compound name and amount large, brand next, then batch number, storage and research use only in the smallest size that is still readable. Print a proof on the real stock and stick it on a real vial before you approve a run.

Why the batch number must match the supplier's

The batch number on a custom peptide label must be the supplier's batch number for that vial, printed exactly as issued, because it is the only link between that vial and its supply record. Change it, shorten it or replace it with your own code and the vial can no longer be traced.

Traceability is what makes a problem solvable. When a buyer reports something about a vial, the batch number lets you and your supplier look up exactly which run it came from, rather than arguing about what probably happened. Primara routes every vial problem by batch number, and that does not change under someone else's label.

It is also what ties a vial to its lab report. Primara publishes reports per batch at /coa as they are issued, and a report covers the batch it names. A custom label with an invented lot code points at no report at all.

If you want your own internal reference as well, add it as a separate line. Never let it replace the supplier's number. Batch numbers and lab reports for resellers covers this in more depth.

The blank labels in every Primara kit

Every Primara kit ships with blank labels: plain white self-adhesive labels, unprinted. They are not a branding tool; they are for marking a vial once it has been made up.

A sealed lyophilised vial identifies itself. A reconstituted one looks like every other small vial of clear liquid in the fridge. The blank labels exist so the person handling it can write what it is and when it was made up at the moment it happens. They are blank on purpose, because no supplier can print that information in advance.

That is a different job from a brand label, and both can sit on the same vial. If you supply your own branded vials, leave room or include your own write-on label for the same purpose. What ships in the box lists the full kit.

How custom-labelled runs work with Primara

Custom-labelled runs are something Primara's supply side can do, and each run is quoted individually on WhatsApp. There is no published price, minimum or turnaround for a labelled run, because all three depend on the compounds, the vial sizes and the volume, and a figure printed here would be wrong for most people reading it.

What to expect in the conversation: you send the compounds and vial sizes, your realistic monthly volume, and what you want printed on the label. The reply tells you whether a labelled run makes sense at that volume, and what will not go on a label, which is anything that cannot be stood behind. Dosing, outcome claims and unscoped testing claims do not go on a vial under any brand.

Be honest with yourself about timing. A labelled run is committed stock that only you can sell, and below a certain run rate reselling under Primara's own label is cheaper and less risky. Private label supply explains where that line sits and why most sellers should start by reselling, and white label peptides compares the options.

A simple label template, as a checklist

A usable peptide label template is a short checklist rather than a design, and every label proof should pass it before a run is approved.

• Top

  Brand, then compound name and amount per vial, the largest text on the label.

• Middle

  Batch or lot number exactly as the supplier issues it, plus a storage line.

• Bottom

  "For research use only. Not for human consumption." and a website or messaging contact.

• Absent

  Dosing, frequencies, outcome words, testing badges without a matching report, and any pharmaceutical brand name.

• Physical

  Synthetic stock, freezer-grade adhesive, smudge-resistant print, a clear window, and a proof stuck on a real vial.

Run the finished proof past your own legal adviser before printing, especially if you plan to sell under your brand beyond a small private list.
