A few of our members asked to post some analytical reports. There are a few ways to analyse a product in this case its fully analysed. They looked for water (Karl Fisher) mostly present if the API (active pharmaceutical ingredient aka raw powders) is not stored properly. The Ph (accidity) mostly due to unpure powders. The identity (if the compound is the compound labeled) in this case does the sample contain drostenolone propionate. The dose (the amount of active ingredients per milliliter). The heavy metals (those can build up in the body) We thought that most API's from India and China would possess a high content of metals -acids etc. That was the  main reason to analyse Underground laboratories.
