The label is the part of a private label product your customers see first. On a research peptide, it also carries the details a lab needs to identify, store and trace the material, and the statement that sets its research-use-only status.
This checklist covers what goes on the vial, what stays off it, and the files to prepare before the proof stage. It describes common practice and how our label system works. It is not legal advice. Check the requirements that apply where you sell.
What every vial label should carry
Our label preview on the homepage shows the standard layout. Each vial label carries:
| Element | Example | Why it matters |
|---|---|---|
| Brand name | Your brand | Identifies whose product it is. |
| Compound name | As listed in the catalog | Must match your listing and the lot records. |
| Amount per vial | 10 mg | Tells the lab how much material is in the vial. |
| Form and count | Lyophilized powder, 1 vial | Describes what is in the vial. |
| Lot number | Lot AWL-0001 | Links the vial to its production record. |
| Storage condition | As stated for the product | Tells the lab how to keep the material. |
| Research-use statement | For research use only. Not for human or veterinary use. | Sets the product's status on the vial itself. |
We include the research-use-only statement on every label. Optional additions include a SKU or catalog number and your website address.
What to keep off the label
A research peptide label describes the material. Keep anything that suggests personal use off the vial, and off your listings and packaging too:
- Health, appearance or performance claims of any kind
- Usage instructions, amounts for personal use or preparation steps
- Images or icons that suggest personal use
- Certifications, grades or approvals that you can't document
- Wording that softens or contradicts the research-use-only statement
Your product pages should say the same thing as your labels. A vial marked "for research use only" sold from a page that implies otherwise sends mixed signals to buyers, marketplaces and payment providers alike. As the brand owner, you are responsible for making the research-use-only status clear to your own customers. Our research use only disclaimer sets out the terms.
Designing for a small vial
A vial label is small, and every line competes for space. A few rules keep it readable.
- Set a clear hierarchy. Brand and compound name are largest. Amount sits close to the compound name. Lot, storage and the research-use statement are smaller but fully legible.
- Use strong contrast. Dark text on a light ground, or the reverse, reads best on curved glass.
- Avoid thin or decorative fonts at small sizes. They break up in print.
- Keep one layout across the line. When the compound name always sits in the same place, customers find it fast and the line looks like one brand.
- Use color to group, not to decorate. A cap color or accent per category helps buyers and your own team tell products apart.
- Plan for cold storage. Labels should stay readable after time in a refrigerator or freezer. Ask about label stock on your brand call.
Files to prepare before the brand call
- Your logo as a vector file: SVG, AI, EPS or PDF. A high-resolution PNG works as a fallback.
- Brand colors as hex codes, plus Pantone references if you have them.
- Font names, if your brand uses specific typefaces.
- Your product list, with compound names and strengths exactly as you will sell them.
- Any extra wording you want on the label, such as a website address.
Starting from scratch? A brand name is enough. We help new brands build a look from the ground up. See custom label peptides for how design works.
Proof review checklist
Every label goes through a proof before printing. Once you approve it, it becomes the reference that delivered labels are checked against. Read it slowly, and check each item:
- Brand name is spelled correctly, in the right typeface and color.
- Each compound name matches the catalog name you are selling under.
- Each strength matches the SKU on your quote.
- The lot number field is present and readable.
- The storage condition is present and correct for each product.
- The research-use-only statement is present, complete and legible.
- Text is legible and high in contrast at actual print size.
- Layout is consistent across every SKU in the line.
- Nothing on the label suggests personal use.
Approve in writing, and keep a copy of the approved proof with its date.
Common label mistakes
- Shortening the compound name so it fits, which makes it differ from the catalog and the lot records.
- Shrinking the research-use statement until it is hard to read.
- Using a different layout for each product, so the line no longer looks like one brand.
- Approving a proof on a phone screen without checking it at actual size.
Records to keep
Good records make the label useful after the sale.
- Keep a log of which lot went into which SKU and which customer order.
- Ask what lot documentation comes with each order, such as a certificate of analysis, and file it by lot number.
- Keep the approved proof for each SKU, with the date it was approved.
- Check that your product listings match the label: name, amount, form, storage and the research-use statement.
Adding products later
Once your label system is approved, a new SKU uses the same design. The new compound slots into the existing layout, which keeps the line consistent and the proof step short.
