In the supplied declarations, KLOW adds 10 mg KPV to the same 10 mg BPC-157, 10 mg TB-500 and 50 mg GHK-Cu amounts listed for GLOW. The difference is one additional component, not an increase in every component.
GLOW and KLOW declared composition
The comparison below transcribes GLOW report MA-BLD-0009 and KLOW report MA-BLD-0010. It describes those named documents; the blend names alone do not define every similarly labelled material.GLOW 70 mg report: MA-BLD-0009 (opens in a new tab)KLOW 80 mg report: MA-BLD-0010 (opens in a new tab)
| Component | GLOW | KLOW |
|---|---|---|
| BPC-157 | 10 mg | 10 mg |
| TB-500 | 10 mg | 10 mg |
| GHK-Cu | 50 mg | 50 mg |
| KPV | Not declared | 10 mg |
| Total | 70 mg | 80 mg |
The amount can stay the same while its fraction changes
Using those label declarations, GHK-Cu is 50/70, about 71.4%, of the GLOW component total and 50/80, or 62.5%, of the KLOW total. Its declared amount is 50 mg in both. These calculated fractions are based on component mass, not chromatographic peak area.GLOW 70 mg report: MA-BLD-0009 (opens in a new tab)KLOW 80 mg report: MA-BLD-0010 (opens in a new tab)
Both reports state that their peptide-related purity figure describes resolved peptide-related substances rather than the proportion of an individual blend component. Keep the mass-fraction calculation separate from that analytical result.GLOW 70 mg report: MA-BLD-0009 (opens in a new tab)KLOW 80 mg report: MA-BLD-0010 (opens in a new tab)
What a structural comparison still needs
Neither supplied report prints a complete sequence and terminal specification for every component. In particular, the TB-500 label should remain as written until its reference structure is documented. A blend has no single peptide sequence, molecular formula or molecular weight.GLOW 70 mg report: MA-BLD-0009 (opens in a new tab)KLOW 80 mg report: MA-BLD-0010 (opens in a new tab)
For a useful comparison, retain each component name and amount, the total, the lot and report revision, then add complete component structures when documented. The individual GLOW and KLOW references carry their own lot-specific result tables so those results need not be repeated here.GLOW 70 mg report: MA-BLD-0009 (opens in a new tab)KLOW 80 mg report: MA-BLD-0010 (opens in a new tab)
