How to read a research pen label

1. Confirm the product identity

Start with the product name and, for a blend, every component listed. Each line in Vivora's current range also carries a catalogue code on its product page: VV-RT for the Retatrutide 40mg pen, VV-TZ for the Tirzepatide 40mg pen, VV-BT for the BPC-157 & TB-500 pen, VV-GL for the GLOW 70mg pen and VV-ND for the NAD+ 1000mg pen. Note the code alongside the name in your records, because it removes ambiguity between similar-sounding products.

The compound and strength on the pen should match the box. If they differ, or the seal is missing, torn or re-stuck, keep the packaging and contact Vivora before using the material in research.

2. Read the stated strength

The strength printed on a label, shown on the listing as the label strength, is a stated quantity. It is not a measurement of the material in your box. Vivora's product pages keep the two apart: the label claim sits beside measured fields that remain pending until a matching independent report is published.

Record the figure exactly as written, including the unit. Every current Vivora listing states its strengths in milligrams. Do not round the figure, convert it or combine it with figures from other products. If the label and the listing disagree, ask Vivora which is correct before recording either.

3. Box total or single pen?

A strength can describe one pen or the whole box. Read the pen count first, then decide what the strength refers to.

• One-pen boxes: Retatrutide 40mg, Tirzepatide 40mg and the BPC-157 & TB-500 blend. The box figure and the pen figure are the same.
• NAD+: 1000mg per box, stated as two 500mg pens. Record both figures.
• GLOW: a 70mg label strength made up of BPC-157 10mg, TB-500 10mg and GHK-Cu 50mg, supplied as two pens. The listing does not state how the amounts are divided between the pens.

Do not divide a box total by the pen count unless the listing states that split. An assumed per-pen figure can look precise while being wrong, and it will travel into every later calculation that uses it.

4. Read a blend component by component

A blend label lists more than one compound. The BPC-157 & TB-500 listing writes its strength as 10mg + 10mg rather than as a single total, which is the clearest form: each compound has its own amount. GLOW lists three components with their own amounts, plus a combined label strength.

Record each component on its own line with its stated amount. A blend total is not a quantity of any one ingredient, and a blend should not be compared with a single-compound product as though it were. The formats and pack contents guide covers this comparison in more detail.

5. Find the batch code

Each Vivora product comes in its own batch-coded window box. The batch code is printed on the box, and it is the identifier you use to look for a published report. Copy it exactly, letters and numbers included, and keep a photo of it with your order reference so the record survives if the outer packaging is later discarded.

Enter the code on the packaging and batch checks page. A match links to the published report for that batch. No match means no report is published there for that code; it does not establish whether the box is genuine. Automatic seal verification is not available, and a seal's format or number alone does not prove authenticity.

6. Match the label to the batch record

When a report is published, compare its sample description and batch identifier with your label before reading any figure. A report applies to its stated batch, not to every product with the same name, and it does not authenticate an individual box. When the record is pending, write down that it is pending and the date you checked. The lab-reports page shows the current status for every product, and our report-reading guide explains how identity, purity and quantity are reported separately.

Check the status again before relying on it, because a report appears on that page once it has been published. If anything does not match, send Vivora clear photos of the box, seal, pen label and batch code with your order reference, and keep the packaging while the enquiry is reviewed.

Common questions

Where is the batch code on a Vivora product?

On the box. Each product comes in its own batch-coded window box, and you enter that code on the verify page to look for a published report.

Does a batch report verify my individual box?

No. A report applies to its stated batch. It does not authenticate an individual box or seal.

What if the pen and the box do not match?

Keep the packaging and contact Vivora with clear photos of the box, seal, pen label and batch code, plus your order reference.

Is the label strength a test result?

No. It is the stated content. A measured figure exists only in a published report for that batch, and a pending report is not a result.
