Three blends, one family: Wolverine, GLOW and KLOW are the three most popular repair-research blends in Canada, and each one is built by adding a peptide to the last. Wolverine pairs BPC-157 and TB-500. GLOW adds GHK-Cu. KLOW adds KPV. This guide explains what each layer contributes, how to choose between them for a given research question, and the price-per-milligram trap to avoid when comparing them.
The blend ladder at a glance
| Wolverine | GLOW | KLOW | |
|---|---|---|---|
| BPC-157 | ✓ | ✓ | ✓ |
| TB-500 | ✓ | ✓ | ✓ |
| GHK-Cu | — | ✓ | ✓ |
| KPV | — | — | ✓ |
| Typical composition | BPC-157 + TB-500 | GHK-Cu 50 + BPC 10 + TB 10 mg | GHK-Cu 50 + BPC 10 + TB 10 + KPV 10 mg |
| Research themes | Blood supply + cell migration | + collagen and matrix | + inflammatory signalling |
| TrueLabs product | BPC-157 + TB-500 | GLOW70 | KLOW80 |
What each component adds
BPC-157: the blood supply
A 15-amino-acid gastric peptide fragment studied for angiogenesis, VEGFR2 signalling and nitric oxide, with the deepest literature in tendon, ligament and gut models. Full guide.
TB-500: the cell movement
A fragment of thymosin beta-4 studied for actin regulation and cell migration, with landmark work in wound and cardiac models. Full guide.
GHK-Cu: the matrix builder
The copper tripeptide behind most collagen research: Maquart’s 1988 fibroblast study and Pickart’s gene-expression work. It shifts the blend from “repair” toward “remodel.” Full guide.
KPV: the inflammation dial
The C-terminal tripeptide of alpha-MSH, studied for reducing NF-κB signalling and inflammation in colitis models (Dalmasso, 2008). It adds an anti-inflammatory research signal to the other three. See KPV.
Which blend fits which research question
- Tendon, ligament or general connective-tissue repair models? Wolverine covers the two classic bottlenecks: getting blood and cells to the injury.
- Skin, wound remodelling, scar or collagen endpoints? GLOW, because GHK-Cu has the strongest collagen literature.
- Models where inflammation is a central variable (gut, skin barrier)? KLOW, for the added KPV signal.
- Need to attribute an effect to one compound? Use separate vials. Blends answer “does the combination do something,” not “which part did it.”
The price-per-mg trap
| Blend | Total content | Price | Total per mg |
|---|---|---|---|
| BPC-157 + TB-500 | 30 mg | $112.00 | $3.73 |
| GLOW | 70 mg | $130.00 | $1.86 |
| KLOW | 80 mg | $150.00 | $1.88 |
At first glance GLOW and KLOW look like half the price per milligram of Wolverine, but most of their mass is GHK-Cu, which costs far less per milligram than BPC-157 or TB-500. The fair comparison is component by component. GLOW and KLOW use the standard formulation found across the market:
| Blend | GHK-Cu | BPC-157 | TB-500 | KPV | Price | Same peptides bought separately | Saving |
|---|---|---|---|---|---|---|---|
| GLOW70 | 50 mg | 10 mg | 10 mg | — | $130 | $174 | $44 (25%) |
| KLOW80 | 50 mg | 10 mg | 10 mg | 10 mg | $150 | $219 | $69 (32%) |
Each blend delivers 10 mg each of BPC-157 and TB-500, the same amounts as the 10 mg single vials, plus GHK-Cu (and KPV in KLOW). If your research needs more BPC-157 and TB-500 per vial and no copper peptide, the BPC-157 + TB-500 blend in 20 or 30 mg is the better fit.
Rule of thumb: compare blends by what is in them and in what amounts, never by total milligrams alone. The same goes for any multi-peptide product from any supplier.
Blends vs separate vials
| Pre-mixed blend | Separate vials | |
|---|---|---|
| Handling | One reconstitution, one vial | Several vials to prepare |
| Ratio control | Fixed | Fully adjustable |
| Attributing effects | Combination only | Compound by compound |
| Verification | Each component needs confirming on the COA | One identity per COA |
For blends in particular, a good COA should confirm each component’s identity, not just report one overall purity number. See how to read a peptide COA.
Frequently asked questions
Cliquez sur une question pour afficher la réponse.
What is the difference between Wolverine, GLOW and KLOW?
Wolverine is BPC-157 plus TB-500. GLOW adds GHK-Cu. KLOW adds GHK-Cu and KPV. Each step adds a research theme: collagen remodelling, then inflammatory signalling.
Is GLOW better than the Wolverine blend?
Neither is better in general. GLOW suits collagen and skin-remodelling research; Wolverine focuses on blood supply and cell migration.
Why does GLOW look cheaper per mg than Wolverine?
Because most of its mass is GHK-Cu, which costs far less per milligram than BPC-157 or TB-500. Total milligrams are not a fair comparison across blends.
Should I buy a blend or separate peptides?
Blends are simpler to handle. Separate vials allow custom ratios and let a study attribute effects to individual compounds.
