Tracing a Wolverine Blend Pen Versus Separate Peptide Pens

Choosing between a BPC-157 TB-500 blend and individual peptides is usually framed as a question about contents or cost. If your lab keeps proper records, there is another angle worth a minute: how many things will you have to trace once the order arrives? Every pen carries a label, and every label needs to be matched to a batch number and, where one exists, a Certificate of Analysis.

The Wolverine blend is one 3ml pen holding BPC-157 20mg and TB-500 20mg (40mg in total), with the label name WOLVERINEKLIK. The STRENGTH bundle is the separate-peptide route: a KLIK500 pen (TB-500 10mg/2mL) and a KLIK157 pen (BPC-157 10mg/2mL). The peptide names are the same, but the paper trail is not.

What is there to trace in each format?

Whether a report exists for a given batch is a separate question. Reports are published on the Certificates of Analysis page and on product pages where one is available, so never assume that every batch has one.

Where the trail breaks with a single blend pen

One pen sounds simpler, and it is: one label, one batch number to write down. The weak point is the report. A document that names only one of the two components, or that does not say which batch it covers, leaves part of the pen untraced.

Read the component names and the batch number on the report before it goes in the file. If either is missing, record that gap rather than filling it from memory.

Where the trail breaks with separate pens

Two pens from one order look like a matched pair, which is exactly why they get filed carelessly. Do not assume both pens share a batch number. Read each label, log each one, and match each to its own report.

The classic slip is a TB-500 report filed under the BPC-157 pen because both arrived in the same box. It only surfaces months later, when someone tries to reconcile the folder.

A tracing record you can copy

1. Record the product name exactly as it appears on the order, plus the label name printed on each pen.
2. Write down the batch number from every label, one line per pen.
3. Note the date received and the condition on arrival: cold, sealed, label legible.
4. Save the report you are matching, with where you found it and the date you downloaded it.
5. Tick that the report's batch number equals the label's, and that every component on the label appears on the report.
6. If no report is available, write "no report available". Do not substitute one from a different batch.
7. Log where the pen is stored (2–8°C, away from light, not frozen).

Which format suits a tidy paper trail?

If your inventory system holds one line per material, the blend fits neatly: one pen, one line, two declared components with their stated amounts. Resist splitting it into two stock lines, because that implies two batches that do not exist.

If your project needs each peptide tracked on its own line, separate pens give each one its own label and report, at the cost of doubling the matching. Both formats are supplied for laboratory research use only, and the paper trail is what lets a lab show exactly which material it held.

Frequently asked questions

Will every pen come with a Certificate of Analysis?

Not necessarily. Reports are published where one is available, so check the listing and the COAs page for the batch you are buying. If you need a report before ordering and cannot find one, ask CLOVA before you pay.

Can I file a blend's report under both peptides?

File it once, against the pen, and list both components on the record. Two stock lines for one pen suggest two batches, which would muddy your trail rather than clarify it.

What if the label and the report do not match?

Keep the pen as received, along with the packaging and the report, and get in touch. The returns and refunds page explains how problems with an order are handled.
