Task #81948

Manufacturer: LeoLab™

Sample: KLOW Stack 80 mg

Date: 06 OCT 2025

On September 30, 2025, LeoLab submitted a KLOW Stack 80 mg (Batch KW10057) sample for independent third-party analysis by Janosik Analytical, a trusted laboratory specializing in pharmaceutical and peptide quality control. The sample was received on October 3, 2025, and the testing was registered under Task Number #81948. The analysis evaluated the mass content of each peptide component within the stack to verify composition accuracy and labeling precision.

Test Summary:

• Peptide Tested: KLOW Stack

• Batch Number: KW10057

• Nominal Quantity: 80 mg

• Measured Components:

  • GHK-Cu — 52.92 mg

  • BPC-157 — 10.80 mg

  • TB-500 (TB4) — 10.31 mg

  • KPV — 13.78 mg

Review:

The analysis by Janoshik Analytical confirmed the accurate composition and labeling of the KLOW Stack. All four peptides were individually quantified, and their measured masses closely matched the expected formulation:

• GHK-Cu was the primary component, measured at 52.92 mg.

• BPC-157 was quantified at 10.80 mg.

• TB-500 (TB4) was measured at 10.31 mg.

• KPV was present at 13.78 mg, as noted in the report comments.

These results confirm the precise formulation of the stack, ensuring that each peptide is present in the correct amount, which is essential for reliable and reproducible research applications.
