Two Pens, One Report? Paperwork for a BPC-157 TB-500 Bundle
A bundle changes how you buy, not what a report covers. Here is how to match batch numbers and documents to each pen, whether you order a bundle, a blend or single peptides.
Most comparisons of a BPC-157 TB-500 bundle vs individual peptides stop at price. The less obvious difference is paperwork. Whichever route you take, the pens that arrive each carry their own label, and any report you rely on has to be matched to the pen in your hand. A bundle puts two pens in one order line. It does not merge two batches into one.
The principle is simple: a report belongs to a batch, and a batch belongs to one product. A report for one pen tells you nothing about the other, however neatly the order was grouped. The rest of this article is about turning that into a routine you can follow at the goods-in bench.
One pen, one label, one batch number
Every pen should carry a label with its product name and a batch number. That number is your link to any Certificate of Analysis. The STRENGTH bundle is two pens, KLIK500 (TB-500 10mg/2mL) and KLIK157 (BPC-157 10mg/2mL), so there are two labels to read and two batch numbers to match.
Reports are published on our COA page and on product pages where one is available. That qualifier matters. Do not assume that every item or every batch has a report, and do not assume that a report you find for one product speaks for another.
How the three buying routes differ
| Route | Pens received | Labels to read | Documents to look for |
|---|---|---|---|
| Two single pens, bought separately | 2 | KLIK157, KLIK500 | One report per pen, from each product page |
| STRENGTH bundle | 2 | KLIK157, KLIK500 | One report per pen, so two, not one |
| Wolverine blend | 1 (3ml) | WOLVERINEKLIK | A report that names the blend and matches the batch on that one label |
The bundle and the singles end up identical on the bench. The Wolverine blend is the odd one out: one pen carries both peptides, so there is one label, and the question becomes whether the report you hold relates to that product and that batch.
Three separate questions
When a report lands in a shared folder, people tend to tick a single box that says "received". Splitting it into three questions is more honest:
- Is it genuine? Does it come from a source you can identify?
- Is it relevant? Does the product name and batch number match the pen you are holding?
- Has someone assessed it? Has a person in the lab, not purchasing, judged whether it answers the question your project actually has?
A genuine report can still describe a different batch. A matching batch number does not mean anyone has read the results. Keeping the three apart stops "we have the document" from quietly turning into "the material has been checked".
Do not let the grouping stretch the evidence
A bundle listing is a purchasing convenience. It tells you which items are sold together, not what has been shown about them together. Background literature on BPC-157 is about BPC-157, and anything on TB-500 is about TB-500. Putting both in one order does not allow one record to speak for the other. The same goes for your own notes: if a statement in your file refers to one peptide, say which.
All of our products are supplied for laboratory research use only, and your file should read that way too. Record what each document is, what it covers and which batch it refers to, rather than assumptions about the material.
A goods-in checklist
When the order arrives, work through this before anything goes into stock:
- Count the pens against the order confirmation.
- Read each label aloud or photograph it: product name, batch number and any strength shown.
- Find the report for each pen, if one is listed, and compare the batch number character by character.
- Note any pen with no matching report, and ask the supplier about it before accepting it into inventory.
- Record who assessed each document and on what date.
- Store the pens as described in the storage guide: refrigerated at 2–8°C, away from light and never frozen.
Frequently asked questions
Does buying a bundle mean one Certificate of Analysis covers both peptides?
Not by default. Each pen has its own batch, and a report is tied to a batch. Check the label on each pen against whichever report is published for it, and treat a missing report as a question for the supplier.
What if the batch number on the label does not match the report?
Stop and ask before the pen goes into stock. It may be a simple mix-up of documents or a newer batch that has not been published yet, but you cannot tell which from the paperwork alone. Keep a note of what you received and when you asked.
Is there a report for every CLOVA product?
No. Reports appear on the COA page and product pages where one is available. If you need one for a particular item, check there first, then ask before you order.
