Summary
The product Sustanon 250 mg/ml, manufactured by Axle Labs, underwent independent testing to verify its authenticity and potency. The sample, identified by batch number C62 Exp 02/2026, was submitted by support@axlelabs.net and analyzed by Janoshik Analytical, a laboratory specializing in pharmaceutical quality control. The analysis measured the total concentration of testosterone esters at 277.34 mg/ml, which is 10.9% above the labeled claim of 250 mg/ml.
The breakdown of individual testosterone esters per milliliter is as follows:
- Testosterone Propionate: 37.96 mg/ml
- Testosterone Phenylpropionate: 65.47 mg/ml
- Testosterone Isocaproate: 64.56 mg/ml
- Testosterone Decanoate: 110.46 mg/ml
Additionally, no guaiacol was detected in the sample.
The testing process began on 28 June 2024, with the sample received on 2 July 2024, and analysis completed on 3 July 2024. The results indicate a moderate overage in concentration, which could impact dosing consistency. Independent third-party testing remains critical to validate these findings comprehensively. This report serves as an educational resource to promote harm reduction and informed decision-making.

Evaluation of Manufacturer-Submitted Testing
This analysis highlights a moderate overdose in total testosterone concentration, measured at 277.34 mg/ml—10.9% above the labeled claim of 250 mg/ml. While the product does contain the correct blend of testosterone esters, the deviation from the expected concentration should be noted, as dosing precision is essential for users managing hormone therapy or performance enhancement.
Additionally, no guaiacol was detected, confirming the absence of this solvent, which can sometimes be present in injectable formulations. Since the test was both submitted and funded by support@axlelabs.net, careful evaluation is needed to assess product consistency across different batches. While Janoshik Analytical is recognized for its transparency and rigorous testing protocols, these findings would benefit from further independent validation through third-party testing.
Conclusion
The analysis confirms that Sustanon 250 mg/ml contains Testosterone Esters at a slightly higher concentration than labeled, with a measured 277.34 mg/ml—10.9% above the stated claim. While this overage may not necessarily indicate poor quality, accurate dosing is crucial for predictable results. The product appears free from contamination, with no guaiacol detected, reinforcing its overall purity.
