The four components are co-lyophilized at the fixed quantities stated on the label and the Certificate of Analysis. They span a wide range of molecular mass and cover acidic, neutral, and basic species, so they are readily resolved from one another by reversed-phase HPLC and by mass spectrometry. Each component’s purity and net content are reported separately on the certificate.
Component 1 (50 mg)
A short-chain tripeptide supplied as a metal complex. The largest component by mass and the source of the blend’s characteristic blue color. Very polar and early-eluting under reversed-phase conditions.
Component 2 (10 mg)
A linear 15-residue synthetic peptide with a proline-rich, acidic sequence. Mid-eluting and well separated from the other three components.
Component 3 (10 mg)
A 43-residue N-terminally acetylated synthetic peptide. The largest component by molecular weight and the latest-eluting peak in the blend.
Component 4 (10 mg)
A basic three-residue synthetic peptide. The smallest component, and the one that distinguishes KLOW from our three-component GLOW blend.
Two handling points specific to this mixture. First, none of the four peptides contains tryptophan or tyrosine, so the blend cannot be quantified at 280 nm; use 214 nm or mass spectrometry for the peptides and the visible absorbance band for the metal-complexed component. Second, the two tripeptides are close in mass and must be resolved chromatographically rather than by mass alone.
| Blend | Components | Total | Key Difference |
|---|---|---|---|
| BPC-157 + TB-500 | Two-component base mixture | 2 peptides | Base pair of the longer-chain components |
| GLOW | Base mixture plus the metal-complexed tripeptide | 3 peptides | Adds the blue, metal-complexed component |
| KLOW | GLOW plus a fourth, basic tripeptide | 4 peptides | Adds the small basic tripeptide component (80 mg total) |
Every lot is tested by an independent third-party laboratory. The tests below correspond to the results reported on the Certificate of Analysis linked on this page. Refer to the certificate for the values for the specific lot.
Purity (HPLC, per component)
Reversed-phase HPLC with low-wavelength UV detection. Each peptide is resolved and its purity reported separately. Specification ≥99% by peak area for each component.
Net Content (per component)
Content of each peptide per vial determined by HPLC peak area against its labeled quantity. Specification 90–115% of label claim for each component, evaluated individually.
Appearance
Visual inspection of the lyophilized material against the specification of a blue lyophilized powder.
Certificate Verification
Each certificate carries a verification code that can be checked directly on the issuing laboratory’s website.
Storage Conditions
Lyophilized (powder): -20°C, protected from light and moisture. Stable for 24+ months under recommended conditions.
Handling: allow the sealed vial to reach room temperature before opening to avoid condensation. Prepared laboratory solutions should be protected from light and air and used promptly; avoid repeated freeze-thaw cycles.
