KLOW vs Glow 70: Comparing Two Repair & Skin Peptide Blends
KLOW and Glow 70 are both multi-peptide repair-and-skin research blends built on the same core. The difference comes down to one component. Here is how they compare.
KLOW and Glow 70 are both multi-peptide research blends aimed at tissue repair and skin quality, and they are far closer to each other than most blend pairings. Both are built on the same three-peptide core; KLOW adds a fourth component. Below is a mechanistic, side-by-side look at both.
The Shared Core: BPC-157, TB-500 and GHK-Cu
Both blends are built on the same three peptides, in the same amounts:
- BPC-157 (10mg): a stable pentadecapeptide based on a sequence found in human gastric juice. It upregulates VEGF and the VEGFR2 receptor to drive angiogenesis at injury sites, and activates FAK-paxillin signalling to speed fibroblast migration and collagen deposition.
- TB-500 (10mg): a synthetic fragment of thymosin beta-4. By binding free G-actin it regulates actin polymerisation, letting repair cells migrate toward damaged tissue. It circulates and acts body-wide rather than locally.
- GHK-Cu (50mg): the copper tripeptide and the largest component of both blends by mass. It stimulates synthesis of collagen types I, III and VI plus decorin, releases VEGF and FGF at repair sites, and acts as an antioxidant and gene-expression modulator.
This core covers the repair cascade from acute injury signalling (BPC-157) through systemic repair-cell mobilisation (TB-500) to structural collagen rebuilding and skin remodelling (GHK-Cu).
What KLOW Adds: KPV
KLOW is supplied as a single 80mg vial: BPC-157 10mg · TB-500 10mg · KPV 10mg · GHK-Cu 50mg. The additional component is KPV, the C-terminal tripeptide (Lys-Pro-Val) of alpha-MSH. It carries the anti-inflammatory and immune-modulating activity of the parent hormone without its pigmentary effects, and is studied for inflammatory and gut-barrier support as well as skin. Full component breakdown is on the KLOW product page.
What Glow 70 Is: The Core Without KPV
Glow 70 is a single 70mg vial: BPC-157 10mg · TB-500 10mg · GHK-Cu 50mg. It is the same core as KLOW with the KPV layer removed, which makes it the leaner of the two: repair and skin regeneration without the dedicated anti-inflammatory and immune component. Because GHK-Cu accounts for 50 of the 70mg, the ratio leans further toward collagen and skin than a pure recovery stack would. Full component detail is on the Glow 70 product page.
Comparison Table
| KLOW | Glow 70 | |
|---|---|---|
| Vial size | 80mg | 70mg |
| BPC-157 | 10mg | 10mg |
| TB-500 | 10mg | 10mg |
| GHK-Cu | 50mg | 50mg |
| KPV | 10mg | Not included |
| Anti-inflammatory / immune layer | Yes (KPV) | No dedicated component |
| GHK-Cu share of total | 63% | 71% |
| Administration | Subcutaneous injection | Subcutaneous injection |
Where the Two Overlap
The overlap is the blend, not just a shared ingredient: BPC-157, TB-500 and GHK-Cu appear in identical amounts in both. Every repair and skin pathway Glow 70 engages is also engaged by KLOW.
The single mechanistic difference is KPV. Research designs that need an explicit inflammatory or gut-barrier arm use KLOW; designs focused on tissue repair and skin quality alone use Glow 70. Because they are not mechanistically distinct approaches to the same endpoint, they are generally studied as alternatives rather than as parallel experimental arms.
