Considering testosterone , trenbolone and other injectables are soluble in oil and alcohol, but not in water, would the following procedure work?:

Take 1 CC of lets say trenbolone (supposely) dosed at 75mg/ml

put it in a vial and slowly fill it with distilled water until the trenbolone accetate powder crystalizes at the bottom of the vial.

filter the water+powder in a .22 UM filter
scrape the powder and weigh it. it should weight around 75mg if the tren is dosed right.

Would this work?
