Two vials of Tirzepatide, manufactured by THELOBSTER, were submitted for potency and purity testing. The samples were from batch LOBSTABROTHERHOOD, and the analysis was both submitted and paid for by the manufacturer. Testing was performed by Janoshik Analytical, an independent pharmaceutical laboratory.
The measured content per vial was 11.10 mg and 11.09 mg, exceeding the typical 10 mg label claim by approximately +10.9% and +10.8%, respectively. Both vials showed extremely high purity: 99.134% and 99.123%, indicating a clean, well-manufactured peptide preparation.

Evaluation of Manufacturer Testing
THELOBSTER’s Tirzepatide vials tested 10.9% above label claim on average and delivered purity levels exceeding 99.1%. These values demonstrate strong manufacturing quality and compound integrity.
That said, the test was manufacturer-funded and submitted, making it an internal QA measure rather than an independent review. While the results are favorable, third-party or individual-funded testing across multiple batches is recommended to validate consistency.
Conclusion
The lab analysis confirms that THELOBSTER Tirzepatide (batch LOBSTABROTHERHOOD) is slightly overdosed and highly pure. The values of 11.10 mg / 11.09 mg and >99.1% purity indicate excellent peptide formulation.
To reinforce consumer trust, ongoing testing by neutral third parties should accompany these strong manufacturer-reported results.

This report is published for educational and harm reduction purposes. It reflects a manufacturer-funded test of a single batch. Broader conclusions about product reliability should be drawn from repeated independent analyses across different lots.
