Summary
AS Labs Sustanon 250, presented in a ten-milliliter multi-dose vial, claims to contain a blend of four testosterone esters totaling 250 mg/ml. Independent testing conducted by SIMEC AG, a renowned analytical laboratory, assessed the product’s composition, potency, and microbiological safety. The analysis revealed a total measured concentration of 231.9 mg/ml, slightly below the label claim.
The breakdown of the testosterone ester concentrations highlighted minor variances, with Testosterone Decanoate measuring significantly lower than the label claim. No microbiological contamination was detected, confirming the sterility of the sample. The product, identified by batch number ASSU-101, was submitted and funded by AnabolicLab.

Evaluation of Testing Results
The analysis confirms that AS Labs Sustanon 250 contains all four testosterone esters as claimed on the label, but with notable deviations in dosing accuracy. The total measured concentration of 231.9 mg/ml falls 7.24% below the label claim, primarily due to a significant underdose of Testosterone Decanoate (-19.50%). Despite this, the product demonstrates good manufacturing consistency for the other esters.
No microbiological contamination was detected, affirming the sterility of the product. However, as this batch was submitted and funded by AnabolicLab, the results pertain solely to this sample and may not represent all batches available to consumers. Independent market-sourced testing is recommended to confirm consistency across batches.
Conclusion
The independent analysis of AS Labs Sustanon 250 confirms that the product is accurately formulated for most components, with the exception of Testosterone Decanoate, which showed a significant underdose. The measured total concentration of 231.9 mg/ml is within an acceptable margin for pharmaceutical products but highlights the importance of continued independent testing to ensure product consistency across batches.
