It can also be obtained in another step.
1. 55.5 ml Oil, 2 ml BA (2%), 20 ml BB (20%) were added to a glass beaker to make a solvent. Weight 30g of steroid powder into the glass beaker.
2. Stir the solvent to start dissolving the powder immediately, but a water bath may be used to speed up the process.
Place the beaker into a pan or something similar in a few centimeters of water: it is important not to use water that is too hot as this can cause some of the product to oxidize 60°C is a good temperature. The goal at this point is to completely dissolve the powder into the solvent. Until the solution is clear, once this has been achieved, proceed to the next step.
3. Remove the 0.22um sterile syringe filter from the package, secure the green needle to the smaller side, wipe the top of the sterile vial with an alcohol swab and insert the green needle and another needle next to it to equalize the internal and external pressures. Place the solution into the syringe to be filtered, this may be a single large syringe or repeated several times using smaller syringes. Apply pressure to the syringe plunger to filter the mixture.
This is the most important part of the process because it is what sterilizes the product. All finished steroids from any steroid lab must go through this process.
Sometimes, one may find that the filter is blocked or the process slows down drastically – to save time, the filter can be replaced with a new one.
Once the product is filtered into sterile vials, the process is complete.
