Writing Up the GLOW Blend Formulation for a Procurement Record
A field-by-field way to write the GLOW formulation into a purchase spec, plus the gaps you should mark as open rather than fill with guesses.

Purchase systems usually ask for a "specification", and a three-peptide pen makes that field awkward. Write too little and nobody can check what arrived. Write too much and you end up recording properties the supplier never stated.
This guide shows how to set out a BPC-157 TB-500 GHK-Cu blend formulation in a procurement record, using CLOVA's GLOW pen as the example. The aim is a spec that a goods-in technician, a researcher and an approver can all read the same way.
The formulation as CLOVA states it
Start with what the GLOW product page actually says, copied exactly. For GLOW, that gives you a short, complete set of entries:
| Field | Entry |
|---|---|
| Product name | GLOW |
| Label name | KLIKGLOW |
| Format | One 3ml pen |
| BPC-157 | 10mg |
| TB-500 | 10mg |
| GHK-Cu | 50mg |
| Total stated content | 70mg |
| Storage | 2–8°C, do not freeze, keep away from light |
| Documentation | Certificate of Analysis where available; match batch number |
Everything in that table comes straight from the listing. That is the point: a spec built from stated facts is one you can check against the pen when it arrives.
Fields that are easy to confuse
Most spec errors come from mixing up fields that sound similar.
Product name and label name. GLOW is the catalogue name; KLIKGLOW is what is printed on the pen. Record both, or goods-in may not recognise the item.
Total and component amounts. The 70mg total is not split evenly. GHK-Cu makes up 50mg of it, with 10mg each of BPC-157 and TB-500. Writing only "70mg blend" loses that.
Units and milligrams. "Quantity 2" should mean two pens. Keep the number of pens in its own field so it never gets read as an amount of peptide.
Don't fill gaps with assumptions
If your project needs a detail the listing does not give, record it as an open question. Do not borrow wording from a similarly named product elsewhere, and do not derive new figures from the stated amounts just to complete a form.
The same goes for properties. A component list does not establish stability, compatibility or anything about how the material behaves. If one of those matters to your work, ask for applicable information and note the answer, with its date, when it arrives. Until then, the field stays marked "to confirm".
It also helps to keep the researcher's requirements separate from the product description. A requirement written into the description column can later look as though the supplier confirmed it.
A spec-entry checklist
Before the specification is submitted, check that it:
- Copies each component name and amount exactly as listed
- States the format as one 3ml pen
- Records the label name, KLIKGLOW
- Gives the number of pens requested in its own field
- Copies the storage conditions from the listing
- Leaves a batch number field to complete on receipt
- Marks any unanswered detail as "to confirm" rather than blank
- Notes the source page and the date it was read
Who signs off the specification
Two people usually need to agree. The researcher confirms the formulation meets the brief, including whether a combined pen suits the study design. The purchasing contact confirms the commercial details: pens, delivery and the date of the information.
Neither should sign for the other. Purchasing staff are not in a position to judge whether 50mg of GHK-Cu alongside the other two suits the work, and researchers should not have to chase delivery terms. Keeping the roles clear means each part of the spec has an owner.
Once the pen arrives, complete the batch number field and check it against the Certificates of Analysis page or the product page, where a report is available. Because GLOW is supplied for research use only, the specification should describe a laboratory material and nothing more.
Frequently asked questions
Does the 70mg total mean equal amounts of each peptide?
No. GLOW contains BPC-157 10mg, TB-500 10mg and GHK-Cu 50mg in one 3ml pen. Record each amount separately so the total is never misread as an even split.
Should the specification include a batch number?
Include the field, but complete it on receipt from the label on the pen. You can then match that number to a published report where one is available.
Can I copy a formulation description from another blend listing?
It is better not to. A similar name or component list does not mean the same amounts or format, so build the spec only from the listing you are actually ordering from.
