Summary
SUSTANON 250 mg/ml, manufactured by Dutch Labs, was independently tested to verify its potency and composition. The sample, identified as batch SU009A, was submitted and funded by DutchLabs.eu for analysis by Janoshik Analytical, a well-regarded laboratory specializing in anabolic steroid testing. The analysis confirmed a total testosterone ester concentration of 265.49 mg/ml, which exceeds 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
The testing process began on 17 October 2024, with the sample received on 5 November 2024, and the analysis completed on 11 November 2024. While the results demonstrate good manufacturing consistency, independent third-party testing of market-procured samples is essential to provide a more unbiased evaluation.

Evaluation of Manufacturer-Submitted Testing
While the analysis confirms accurate dosing, it is important to consider potential biases due to the sample being both submitted and funded by the manufacturer. Manufacturer-submitted samples may be selectively chosen to reflect the best possible quality, which may not represent the consistency of market-available products. To ensure broader reliability, independent testing of multiple batches sourced from the market is strongly recommended.
Conclusion
The analysis of SUSTANON 250 mg/ml verifies the presence and accurate concentrations of the listed testosterone esters, with a total concentration exceeding the label claim by 6.20%. These results reflect excellent quality control for this batch. However, independent third-party testing remains vital to confirm consistency across different batches and to mitigate any potential biases from manufacturer-submitted samples.
