Summary
The product Sustanon 250 mg/ml, manufactured by PrimePharma, was analyzed to verify its composition and potency. The sample, identified by batch number PP1764, was submitted by the reseller Opitropin.EU and tested by Janoshik Analytical, a laboratory renowned for its expertise in pharmaceutical quality analysis. The analysis determined a total concentration of 264.77 mg/ml for the combined testosterone esters, slightly exceeding the labeled specification by 5.91%. This batch-specific result highlights accurate dosing with a minor overage.
The breakdown of the testosterone ester concentrations is as follows:
- Testosterone Propionate: 39.00 mg/ml
- Testosterone Phenylpropionate: 64.92 mg/ml
- Testosterone Isocaproate: 53.29 mg/ml
- Testosterone Decanoate: 107.55 mg/ml
The testing process began on 2 May 2023, with the sample received on 11 May 2023, and the analysis concluded on 15 May 2023. Reseller-submitted testing, while valuable for market representation, warrants careful scrutiny due to potential batch selection bias. Independent third-party verification remains an essential component in confirming consistency across multiple batches. This report is intended to provide educational insights and support harm reduction practices.

Evaluation of Reseller-Submitted Testing
This test report was submitted and funded by Opitropin.EU, a reseller of anabolic products. While reseller-submitted samples often represent market-available products more accurately than manufacturer-provided ones, they are still subject to potential bias. Resellers may selectively submit batches that are known to meet or exceed label claims, which could misrepresent the overall product consistency.
The analysis conducted by Janoshik Analytical supports the validity of this particular sample, as the results align closely with the labeled specification. However, independent third-party testing is recommended to verify the consistency of multiple batches beyond this reseller-provided sample. Transparency in testing practices is crucial for building consumer confidence and ensuring reliable product quality.
Conclusion
The analysis demonstrates that Sustanon 250 mg/ml from PrimePharma is accurately dosed, with a total measured concentration of 264.77 mg/ml, reflecting a 5.91% overage. The breakdown of individual testosterone esters further highlights the product’s adherence to its label claims. While this result reflects high manufacturing standards, additional independent testing is encouraged to confirm consistency across broader market samples. This report serves as a valuable resource for harm reduction and educational purposes, helping consumers make informed decisions.
