Summary
The product SUSTANON 250 mg/ml, manufactured by Dutch Labs under batch SU009A, was analyzed to verify its composition and potency. The sample, submitted and funded by DutchLabs.eu, was tested by Janoshik Analytical, a well-regarded laboratory specializing in anabolic steroid analysis. The analysis confirmed a total testosterone ester concentration of 265.49 mg/ml, exceeding the labeled specification by 6.20%.
The breakdown of individual testosterone esters is as follows:
- Testosterone Propionate: 31.10 mg/ml
- Testosterone Phenylpropionate: 64.06 mg/ml
- Testosterone Isocaproate: 62.51 mg/ml
- Testosterone Decanoate: 107.82 mg/ml
Testing was initiated on 17 October 2024, the sample was received on 5 November 2024, and the analysis was completed on 11 November 2024. While the variance indicates a slight overdose, the results suggest good manufacturing consistency. Independent third-party testing of market-procured samples is recommended to ensure unbiased evaluation.

Evaluation of Manufacturer-Submitted Testing
The analysis revealed a 6.20% overdose relative to the labeled claim, suggesting consistent quality control by Dutch Labs. However, since the sample was both submitted and funded by the manufacturer, there is a potential for selective sample submission. Independent testing using market-purchased samples is advised for a more objective assessment.
Conclusion
The analysis confirms that SUSTANON 250 mg/ml contains a total testosterone ester concentration of 265.49 mg/ml, exceeding the labeled claim by 6.20%. This slight overdose demonstrates strong quality control. Nevertheless, independent validation is crucial to confirm consistency across different batches and to mitigate potential biases from manufacturer-submitted samples.
