Step 1: Attach 22guage needle to the whatman syringe filter. Step 2: Swab the top of the vial with alcohol wipes to sterilize it. Step 3: Insert the 20guage syringe filtered needle into the septum of the vial (the rubber piece). Step 4: Insert the second needle tip into the septum to vent the pressure that will build from injecting the solution into the vial. Step 5: Draw up the warmed solution. Having it warmed will speed up the process and make it easier to filter. Step 6： Attach the barrel of the syringe to the whatman syringe filter. push the solution through the whatman syringe filter into the sterile vial. Use constant pressure. It will only trickle. Be sure not to apply immense pressure as that will split the syringe filter and you will have a mess everywhere. Step 7: Detach the syringe barrel from the whatman syringe filter and draw up another 10mls of your steroid solution. Reattach to the syringe filter and filter it into the new sterile vial. .If using 10ml vials, Just repeat steps 9 thru 12 filtering 10mls of the solution in each of the vials. Final product: Your choice as to which size vial you use. You will end up with either One 40ml vial or Two 20ml vials or Four 10mls vials at 250mg/ml Places to get some of the items needed for this conversion Jennings JScale HP-100X Gram Precision Digital Pocket Scale 100g x 0.01g with 100 Gram Calibration Weight400ml beaker60ml syringe Curity Medium 2 Ply Alcohol Prep Pads Whatman Syringe Filter Sterile Clear Vials 10ml (Metallic Gold )20 ml Clear Sealed Sterile Glass Vial50 ml Clear Sealed Sterile Glass Vial3cc Syringe with 25-Guage x 1 1/2″SINGLE Regular Luer Tip Syringe (3 mL) with Needle (20 guage x 1-1/2″)Glass Stir Rod 12″ – 1 EA Grape Seed Oil – 8 oz. – Liquid.
