Home Brew Cypionate

So i just got in some Cyp powder to make. Ive been home brewing for about 5 years now. To keep it short as i was filtering the oil through the whatman filter it literally started crash about 5 minutes in. I wasnt even done filtering it all by the time the oil in the bottle already started crashing. I have been using the same supplier for 4-5 years as well. Never had a problem with quality of powder but due to the fact that it crashed literally immediately it leads me to believe the powder is bad. Any advice from guys who home brew would be really appreciated.
