SUBSTANCE TESTING REPORT
DIANA Potency Verification
1. Introduction
Verification of DIANA potency and comprehensive impurity profiling.
2. Methodology
HPLC,MS
3. Results
| Parameter | Value |
|---|---|
| Sample Identification | DIANA (Lote# DIA1529-2024) |
| Concentration | 1.95 mg/mL ± 0.09 |
| Purity | 98.8% |
| Impurities | <1.2% |
4. Discussion
The HPLC method demonstrated excellent linearity (R²=0.9998) across the concentration range for methandienone quantification. Mass spectrometry confirmed the molecular ion at m/z 301.2 and characteristic fragmentation pattern. Related substances analysis detected two impurities at levels of 0.5% and 0.4% respectively. Forced degradation studies showed the product is stable under thermal conditions but susceptible to oxidation. Chiral purity was confirmed by chiral HPLC.
5. Conclusion
DIANA exhibits appropriate potency and purity with impurity levels well within acceptance criteria for methandienone.
