A Plain Glossary for BPC-157, TB-500 and GHK-Cu Blend Listings

So, what is a BPC-157 TB-500 GHK-Cu blend? In a catalogue, it is one product that lists three named research peptides together instead of selling each one separately. CLOVA's version is called GLOW: a single 3ml pen containing BPC-157 10mg, TB-500 10mg and GHK-Cu 50mg, which makes 70mg in total.

The name is simple. The words around it are where buyers tend to get tangled, because a listing, a pen label and a certificate each use slightly different language for the same thing. This glossary walks through those terms in the order you will meet them.

The three component names

These are shorthand names for the individual research peptides. They appear in listings in several spellings, such as BPC157 without the hyphen, so do not be alarmed by minor differences. What matters is that you can trace each name to a stated amount.

• BPC-157. One of the three components. In the GLOW pen it is listed at 10mg.
• TB-500. The second component, also listed at 10mg in the GLOW pen.
• GHK-Cu. The third component. The "Cu" marks copper in the name, and in the GLOW pen it is listed at 50mg. It is also sold on its own as a separate GHK-Cu listing.

The words describing the product itself

• Blend. A single product that contains more than one named component. A blend is not the same as a bundle, where separate items are sold together.
• Component. One named ingredient within the blend. Each should have its own stated amount.
• Pen. The presentation format used for CLOVA's blends. The GLOW pen is 3ml.
• Total content. The sum of the stated component amounts. For GLOW that is 10mg + 10mg + 50mg = 70mg. People often mix up the 50mg GHK-Cu figure, the 70mg total and the 3ml pen volume, but they are three different measurements.
• Product name and label name. The shop calls it GLOW; the printed label reads KLIKGLOW. Both refer to the same product, and records should note the pair so nobody wonders whether they are different items.

The words that appear on paperwork

• Batch number. The reference printed on the label that ties the item you hold to a production batch. It is the link between your pen and any report.
• Certificate of Analysis (COA). A document reporting results from analysis of an identified sample. CLOVA publishes reports on the COA page and on product pages where one is available, which is not the same as every product or batch having one.
• Purity figure. A number reported for a particular test on a particular sample. It belongs on a report, with the batch it describes, and not in a product name.
• Research use only. The supply basis. These materials are provided for laboratory research and not for human or veterinary use; there is more in the explainer on what the wording means.

Words that look like claims but are not

A product name is a label chosen by the shop. GLOW is a catalogue name; it does not describe an outcome, and nothing about the word should be read as a statement about what the contents do. Likewise "blend" describes how the product is put together, not how it performs.

If you see wording on any third-party page that attaches outcomes to the name, treat it as separate from the listing and do not copy it into your records.

A five-point check for reading a blend listing

1. Are all three component names present, and does each have a stated amount?
2. Does the total equal the sum of the parts?
3. Does the pen volume match the one on the listing and your order?
4. Is the label name noted next to the product name?
5. Is there a batch number to match against a report, where one is available?

If any answer is "not stated", write that in your record and ask. Do not fill the gap from another seller's page, since a shared nickname does not mean a shared specification.

Frequently asked questions

Is a three-peptide blend the same as three separate peptides?

No. The same names are involved, but a blend is supplied as one pen with fixed stated amounts, while separate listings are separate items with their own labels and documents. Which suits a project is a design decision for the researchers.

Do all products called GLOW contain the same thing?

You should not assume so. Use the amounts stated on the CLOVA product page and label, and confirm anything else directly with the supplier you are buying from.

Where should I look for a report on a blend?

Start with the product page and the COA page, then match the batch number on your label to any report you find. If none is shown for your batch, ask the supplier before you rely on one.
