Protocol / Research Dosing Guide
An evidence-organized guide to the three-component Glow research blend, separating vendor marketing from what has actually been studied — which is the individual ingredients, never the mixture.
Glow is a commercial name for a pre-mixed research vial sold as a GHK-Cu, BPC-157 and TB-500 combination — essentially the Klow blend without KPV. No study of this fixed combination in humans, animals, or cell systems was identified. Evidence for each component belongs to that component alone and does not transfer to the mixture.
Why researchers care
Skin, collagen and combined repair-signaling research claims
Class
Vendor-defined GHK-Cu + BPC-157 + TB-500 blend

Vendor listings describe subcutaneous injection of a reconstituted blend

Regulatory status
Not FDA approved; research-use product
The vendor listing reviewed (a 70 mg vial) does not publish a per-component breakdown, so the amount of each ingredient in the vial is not verified. No studied schedule exists for the combination; any schedule shown by a seller is a marketing convention, not a studied regimen.
| Phase or study | Amount | Frequency / evidence |
|---|---|---|
| Combination schedule | Not established | No controlled study of this blend exists |
| Per-component amounts in the vial | Not published on the reviewed listing | Fixed ratios cannot be adjusted independently |
| Rest or repeat interval | Not established | No combination study defines one |
No study establishes an appropriate human amount, frequency, cycle, rest period, or taper for this blend. Component-level findings cannot be summed into a blend protocol.
Neutral research-material planning only. This does not establish an appropriate amount or route.

| Route | What is reported | Evidence limit |
|---|---|---|
| Subcutaneous | Vendor listings describe a reconstituted injectable blend | No blend-level human study |
| Topical or cosmetic | GHK-Cu appears in cosmetic products on its own | Does not establish blend use by any route |
| Oral | Not established | No blend exposure data |
| Route conversion | None available | Routes are not interchangeable |
Routes and amounts are not interchangeable unless a verified study explicitly establishes a conversion.
| Measure | Finding | Evidence limit |
|---|---|---|
| Blend half-life | Not established | No combination pharmacokinetic study |
| GHK-Cu human half-life | Not established | No formal human PK study identified |
| BPC-157 human half-life | Not established | Animal PK cannot define human clearance |
| TB-500 fragment half-life | Not established | No formal PK study identified |
| Route | Amount | Frequency | Source | Human validation |
|---|---|---|---|---|
| Subcutaneous blend | Not established | — | No studied regimen | No |
| Per-component amount | Not published on listing | — | Vendor listing | No |
Published study values describe those studies. Community-reported values are not validated dosing recommendations.
Concentration: 23.333 mg/mL
| Entered amount | Volume | U-100 units |

| 3.5 mg | 0.15 mL | 15 units |
| 7 mg | 0.3 mL | 30 units |
| 10.5 mg | 0.45 mL | 45 units |
Reconstitution does not establish identity, purity, sterility, stability, or an appropriate amount.
