If all else fails you use one of the accessory shops listed here (FR and PM me if you need to). You get a sealed sterile vial and a syringe filter. Attach filter to syringe, push air into mast vial, extract mast through filter, insert a small (like 23-27) gauge pin without syringe into septum of sterile vial (to release internal pressure) then detach filter from loaded syringe, attach a clean pin to it, inject filtered oil into sterile vial.

This will provide the smoothest new oil possible and ensure sterility.

Unfortunately some of these methods expose the hormone to too much heat and it will degrade the hormone decreasing its effectiveness.

Injecting oil with crystals, even crystals too small to see, will crash in the muscle and provide a very unpleasant next few days/weeks. (Swagger of a cripple)

If I have crashed gear I wrap it up in a heating pad on high until the crystals are gone.

well what have you tried? I just had the same problem and the best way for me is to use wet heat to heat the vial. take a pan of water place the vial in and turn it on to a boil and leave in for about 10 min take it out and shake.. in my experience it will turn cloudy first before it reconstitutes... and repeat until clear may take 2-3 times... should work!!!!

good luck
