A blend puts two or more peptides in a single lyophilized vial, for example BPC-157 with TB-500. Blends save handling steps in multi-compound study designs. They also make quality checks harder, because one purity number can’t describe two peptides. Orion Peptides blends are supplied for laboratory research only. Not for human or veterinary use.
Why blends need a stricter certificate
In a single-peptide vial, HPLC purity and an identity test tell most of the story. In a blend, you also need to know:
- That each component is present. The identity test should confirm every peptide on the label.
- How much of each is present. A “10 mg / 10 mg” blend should show measured content for each component, not just a total.
- That the peaks are resolved. The chromatogram should separate the components so each can be assessed.
A blend COA that gives one purity figure and no per-component data is the most common weak point across the market.
Blend COA checklist
| Check | Single peptide | Blend |
|---|---|---|
| HPLC chromatogram | Required | Required, components resolved |
| Identity test | Compound confirmed | Every component confirmed |
| Quantity | Net mg | Net mg per component |
| Lab + date | Required | Required |

Orion Peptides research blends
Every Orion Peptides batch is tested by a third-party laboratory, Hyte Research Division. Certificates are on our COA Verification page. Browse all Peptide Blends, including:
- BPC-157 10 mg + TB-500 10 mg blend
- BPC-157 10 mg + TB-500 20 mg blend
- Glow blend (BPC-157, TB-500, GHK-Cu)
- KLOW blend 80 mg
Prefer separate vials? See BPC-157 and TB-500 Third-Party Testing. For composition background, see KLOW Peptide Composition and Comparisons Among BPC-157, TB-500 and GHK-Cu.
Blend or separate vials?
Blends suit designs that always use the same fixed ratio. Separate vials suit designs that vary ratios or test each compound alone, and each vial gets its own simpler certificate.

FAQ
What is in the Orion Peptides Glow blend? BPC-157, TB-500 and GHK-Cu in one lyophilized vial. See the compound page for amounts.
Are blends tested the same way as single peptides? They are tested by the same third-party lab. Check the certificate for per-component identity and quantity.
Are blends for human use? No. Laboratory research only.
